October 2020: Role of inland saline wetland ecosystems in the face of climate change
October 15, 2020 | 1:00 p.m. ET
Role of inland saline wetland ecosystems in the face of climate change
Wetlands are diverse ecosystems in which even slight alteration can result in an enormous socio-ecological, physio-chemical and economic impact. Inland saline wetlands are unique in nature, yet are among the least-studied wetlands. My research examines the largest saline wetland of India, Sambhar Salt Lake. Although it was designated a Ramsar site on March 23, 1990 and is considered an Important Bird Area, it does not fall under any protected area network. It used to be the critical habitat of 289 migratory bird species along the West Pacific Flyway, East-Asian Australasian Flyway and Central Asian Flyway. That number has been reduced to only 31 species, per our joint bird census report with Asian Water Census volunteers. To address this decline, this study analyzed soil salinity indices using satellite data from 1989, 1998, 2008, 2014, 2019 and 2020, and integrating climatic parameters and ground data. We see the impact of past climatic trends, as well as the lockdown due to COVID-19 from March 24, 2020, to May 30, 2020, on the lake. Results demonstrate that salinity has decreased drastically over the years until 2019. However, the lake is recovering during the pandemic. The lake is now full of water, and the soil salinity value has increased, indicating its unique populations of halophiles and halophytes are recovering. Once again, Sambhar Salt Lake is primed for rich biodiversity, assuming minimal human interference.

September 2020: Urban Wetlands and Water Management
September 17, 2020 | 1:00 p.m. ET
Urban Wetlands and Water Management
Wetlands help make cities livable. They reduce flooding, replenish drinking water, filter waste, and provide green spaces and outdoor classroom education opportunities for neighborhood schools. Yet, most people are unaware of the services urban wetlands provide their communities. In fact, urban wetlands are often viewed by the public as wastelands to be infilled for development, a place to dump trash, and/or too small and degraded to be worthy of protection or restoration by wetland managers with limited resources. In 2019, ASWM and an interdisciplinary workgroup began a project to address these challenges by: exploring ways in which Wetland Program Plans and the Core Elements Framework can do more to help local communities manage urban wetlands; identifying opportunities for mapping and functional assessment of urban wetlands to improve restoration and protection efforts; and facilitating research and peer to peer exchange on innovative funding and financing methods for nature-based projects. Findings, case studies, and recommendations resulting from this project will be summarized into a strategic guide by the end of 2020. This presentation will provide an overview of the project, summarize preliminary findings and highlight examples where urban wetlands have been successfully restored, enhanced or protected to improve human health and well being. Discussion of case studies will include how the projects were funded, whether functional mapping was used to prioritize restoration and protection, policy tools used to support the project, and resulting or expected benefits.

August 2020: Restoring Native Clam Communities for Improved Water Quality and Economic Resilience in the Indian River Lagoon
August 20, 2020 | 1:00 p.m. ET
Restoring Native Clam Communities for Improved Water Quality and Economic Resilience in the Indian River Lagoon
In this webinar, Dr. Todd Osborne, the Primary Investigator of the Indian River Lagoon Clam Restoration Initiative, will discuss the concept of leveraging natural selection of hard clams by environmental pressures (harmful algal blooms, hypoxia, nutrient pollution) to improve water quality. By identifying small populations of clams that survived devastating environmental decline and then breeding these clams in the laboratory, the Clam Restoration Initiative has repatriated 3.5 million adult clams to the IRL that filter 20-30 gallons of water per day and tolerate the degraded water quality conditions currently present. This biological filtration reduces turbidity, retains nutrients, and helps control algal populations all of which impact the ecologically sensitive native seagrass communities. The return of seagrasses to the IRL is paramount to returning the lagoon to a healthy status and is a primary focus of current restoration strategies for this Estuary of National Significance. The process of identifying broodstock, rearing clams and the intricacies of repatriation will be discussed in detail as will results of the first year of effort on this work. Finally, discussion of successful collaboration strategies with pubic and private entities will be presented as well as the future vision of the Clam Restoration Initiative.
Presenter Todd Osborne:

July 2020: Can Biochar Increase Carbon Sequestration in Wetland Restoration Projects?
July 16, 2020 | 1:00 p.m. ET
Can Biochar Increase Carbon Sequestration in Wetland Restoration Projects?
Abstract: Biochar (a carbonaceous soil additive) is considered as one of the promising options to enhance the soil carbon sink due to its resistance to biotic and abiotic degradation. Coastal managers in the U.S. are increasingly interested in incorporating biochar into wetland restoration and stormwater mitigation projects because of its dual benefits in terms of enhancing denitrification and sequestering carbon; however, little information is available on the ability of biochar to sequester carbon in coastal wetlands. In the present study, we conducted a factorial experiment to examine the initial changes in sequestration of wetland sediments amended without and with different levels (0%, 10%, and 20%, v/v) and types of commercially obtained biochar (bamboo, hardwood, softwood, rice husk, and marine feedstocks). Carbon mineralization was monitored by measuring carbon dioxide (CO2) fluxes from the incubated pots. Preliminary data showed increased rates of CO2 emissions in an initial couple of incubation weeks, while the escalated emission rates diminished in the following incubation weeks indicating sequestration of CO2 by soils amended with biochars such as bamboo, hardwood, softwood, and rice husk. Contrastingly, the marine soil amendment continued emitting CO2 over the entire study period which might be due to its high labile nature. Overall, the biochar amended sediments sequestered higher CO2 compared to the non-amended soils. These results are preliminary and will be further elucidated by microbial biomass analysis in the future. The study provides an insight for the coastal managers looking for sustainable strategies towards climate change mitigation.

June 2020: Roadside Right-of-Way Wetlands Resulting from Road Construction and Mowing
June 18, 2020 | 1:00 p.m. ET
Roadside Right-of-Way (ROW) Wetlands Resulting from Road Construction and Mowing Practices
Wetland right of way (ROW) - Lowland/wetland study site along the roadside ROW.
Wetland right of way (ROW) 2 - Bridge overpass with mowed plots near to connective waterway.
Roadside right-of-ways (ROW) undergo regular disturbances such as mowing, maintenance, and road developments that affect soils, groundwater, surface hydrology, and vegetation composition. Strips of roadside ROW ditches are morphing into wetlands because of road developments such as reduced mowing practices, bridges and culverts being put in/modified, etc. The construction of roads inadvertently creates functional wetlands that might be governed by wetland regulations. The study was conducted using 10 research plots situated along Highway 25 in Mississippi, USA. The research plots consisted of three different mowing treatments and different site elevations (uplands vs. riparian lowland/wetland areas). The riparian lowland areas were influenced by overbank inundations by streams and ROW drainage ditches. Using line transect sampling methodology, over 277 native and nonnative plant species (around 20% were wetland indicator species), of forbs, legumes, grasses, rushes, sedges, vines, shrubs, and trees were found on the roadside ROW in northeastern Mississippi. Total percent coverage of native and nonnative plants within different growth form categories did not statistically differ among treatments (F2,96 = 0.45, P = 0.83). However, percent coverage differed between uplands and riparian lowlands (F1,96 = 18.22, P < 0.001), between years (F1,96 = 14.54, P < 0.001), and between fall and spring seasons (F1,96 = 16.25, P < 0.001). Percent coverage and species richness from the growth form categories was found in the lowland sites in the greatest quantity. These road ditches may not always contain water, but many still represent wetland ecosystems and serve as “significant jurisdictional connectivity” to navigable waters. Numerous wetland wildlife species have been observed using and successfully raising offspring in these “roadside wetlands” due to anthropomorphic disturbances.

May 2020: Before the Ghosts Appear: Identifying the Effects of Chronic Saltwater Intrusion on Coastal Floodplain Swamps Using Remote Sensing
Before the Ghosts Appear: Identifying the Effects of Chronic Saltwater Intrusion on Coastal Floodplain Swamps Using Remote Sensing
These is a photo of freshwater swamps on the Suwannee River.
Abstract: Studying chronic, low-level saltwater intrusion (SWI) impacts on coastal floodplain swamps (CFS) over large spatiotemporal scales is challenging and resource intensive, however, remote sensing (RS) techniques offer an alternate approach to traditional field methods that can be used to answer a broad array ecological questions. In this study, I developed a suite of hypotheses based upon expected changes to phenology and vegetation characteristics resulting from chronic, low-level SWI. CFS sites were selected across the northern Gulf of Mexico with water quality data being used to partition sites into upstream and downstream with downstream sites currently experiencing chronic, low-level SWI. Enhanced vegetation index (EVI) data were calculated at each site using surface reflectance data from the MODIS Terra satellite over the period from 2000 to 2018. Four hypotheses, out of nine, were supported ≥ 80% across all sites. The hypotheses that were best supported were centered on descriptive statistics of median and distribution, whereas the other five hypotheses relied on change (i.e. slope) over time as a central component. The inherent intra- and interannual variation in CFS EVI can mask any long-term trends that maybe occurring at a given site. The ecologically-based approach developed here offers future researchers a low cost way to monitor and investigate CFS that are suspected of chronic, low-level SWI.
Elliott White Jr., PhD is a research associate in the Environmental Sciences department at the University of Virginia. Elliott’s research seeks to capture and understand the effects sea level rise (SLR) and saltwater intrusion (SWI) on coastal wetlands across large geographic gradients. His current research efforts involve mapping loss and conversion of Atlantic Coast and northern Gulf of Mexico wetlands due to SWI and SLR over the past 30 years. Next steps of this research will be finding coastal wetlands that are vulnerable and generating probability driven maps of future wetland coverage. The goal of this research is to guide future research and conservation efforts. His doctoral research sought to understand how coastal floodplain swamp gaseous carbon flux, nitrogen storage, vegetative community structure and composition, and health shift with the landward advance of riverine and groundwater isohalines. Elliott’s doctoral research covered a large geographic range taking place across the northern Gulf Mexico in Florida, Louisiana, and Texas. He received his PhD in environmental engineering sciences from the University of Florida in 2019 and his BS in biology and animal ecology from Iowa State University in 2015.
April 2020: Convergence of Wetland Science and Technology
Convergence of Wetland Science and Technology
As an ecologist conducting wetlands delineations, threatened & endangered species surveys, and baseline ecological inventories for over 17 years around the world, I have been able to avoid the rise of tech for many years more than people in most other professions, due to the lack of quality tools available to environmental scientists. It is the 21st century, however, and the wheel of innovation is rolling through every profession, including earth sciences. In this presentation, we will discuss how it is essential that tech be simple, intuitive, and shaped by scientists. We need technology that wraps and enhances our existing methodologies and protocols. Our shared vision as scientists is that good technology should be almost invisible and is not simply a transference of inefficiency from one process to another. The wrong kind of technology just adds to the stresses of balancing conservation and monitoring with permitting and state and federal changes in the legal jurisdiction of water bodies. Data collection and analysis are the foundation for the creation of knowledge, and knowledge leads to the protection of our natural resources while enabling economic progress. The right kind of technology gets out of the scientist’s way and allows for a greater percentage of attention and focus on the creation of this critical knowledge. In this webinar, we will discuss technology trends in the wetland science community from GPS collectors, field equipment, data collection applications, digitization of the regulatory review process, with the goal-setting a high bar of expectations for new technologies that are becoming part of our everyday workflows.

Abstract: Invasive plants can take over to a point of no return within a disturbed or degraded wetland and create challenges for restoration or reclamation of wetlands. Monitoring for invasive species can result in early detection of new species, tracking the spread of existing invasive plants, and helping to identify appropriate treatment options, or whether it makes sense not to actively manage. Monitoring for invasive species can help restoration projects be successful by giving native species the opportunity to establish, improving biodiversity, and overall wetland functions and values. Our presentation will explore four (4) Vermont Case Studies of Wetland Restoration, Enhancement, and Invasive Species Management.

February 2020: How certification of Professional Wetland Scientists can improve wetland practice around the World
February 20, 2020 | 1:00 PM ET
How certification of Professional Wetland Scientists can improve wetland practice around the world
Abstract: The Society of Wetland Scientists was formed to promote understanding, conservation, protection, restoration, science-based management and sustainability of wetlands. The Society developed a program in 1994 for certification of wetland science training and experience to meet the needs of professional ecologists, hydrologists, soil scientists, educators, government agency professionals, consultants, and others who practice wetland science. The program is aimed at serving the public and governments’ need to identify qualified individuals to assess and manage wetland resources. It provides a comparable professional certification system to other professions such as engineering, architecture and landscape architecture and is internationally recognized. Certification signifies that the academic and work experience of a Professional Wetland Scientist (PWS) meets the standards expected by her or his peers of a practicing wetland professional and provides acknowledgment of adherence to standards of professional ethics with regard to the conduct and practice of wetland science. Certification enhances the recognition of wetland science within other disciplines, especially in multi-disciplinary work environments. Wetland Professional in Training (WPIT) is considered a preliminary step for people who meet the basic educational requirements but do not yet have the experience requirements. This presentation discusses the benefits of PWS accreditation, gives straightforward guidance of how to apply and considers why the PWS program supports the raising of professional standards internationally, how it recognizes the importance of a career in wetland science, how it raises the profile and importance of wetlands and how the program enables more effective wetland conservation and protection around the world.

December 2019: Withering Wetlands - Global Trends in Wetland Loss and Degradation: Why, and What Can Be Done About It?
Withering Wetlands - Global Trends in Wetland Loss and Degradation: Why, and What Can Be Done About It?
Wetlands deliver vital benefits to people and their livelihoods, benefits of huge economic value: recently re-estimated as at least $47 trillion per year - 43% of the value of all the earth's ecosystems, despite wetlands forcing less than 4% of the earth's surface. Yet people have been converting and destroying wetlands for centuries, and this destruction continues in all parts of the world. Furthermore, new evidence indicates that although many wetlands, particularly small ones, are still in good condition, deterioration of the condition (ecological character) of our remaining wetlands is becoming increasingly widespread, although less so for internationally important wetlands (Ramsar Sites) than other wetlands. This webinar will then look at what is driving this continuing loss and degradation, both directly and indirectly, and identify what the world's people, and specifically the Society of Wetland Scientists (SWS) can and should be doing to turn round the continuing destruction of the wetlands we all depend on for our future survival, including through their role in minimising impacts of our changing climate.

November 2019: Coastal Wetlands and Climate Change
Coastal Wetlands and Climate Change
Presented by: Dr. Ariana Sutton-Grier and Dr. Michael Osland
Coastal marsh in San Bernard National Wildlife Refuge (Texas, USA)
Coastal wetlands provide critical fish and wildlife habitat and support many societal benefits, including protection of human communities from storms and maintenance of productive coastal fisheries. However, due to climate change and rising sea levels, the coastal wetlands present today are expected to be much different by the end of the century. Here we present results regarding some of the changes that are expected, with an emphasis on the role of warming winter temperature extremes, rising sea levels, and changing precipitation regimes. We also examine the role of wetlands in climate change adaptation (e.g., as natural infrastructure) and mitigation (e.g., blue carbon storage).

October 2019: Toxic Pollution in Wetlands and Remediation Actions
Toxic Pollution in Wetlands and Remediation Actions
Wetlands are valuable ecosystems with many functions, including habitat for fish and wildlife, protecting water quality, erosion prevention, flood storage, and recreation. Wetlands are also critical habitat for many species of migratory birds, including game species that are of great ecological and economic value. Wetland fauna are threatened by toxic pollution from point and non-point sources of wastewater, that is discharged into wetlands by industry, municipalities, and other land uses within their drainage basins. Pesticides and biocides are key contaminants. Other pollutants may include, lead and metal pollution, arsenic, mercury, pharmaceuticals, toxic algae/ cyanotoxins, and generic sediment contamination.
Recently, more attention has been given to toxic threats in Asian Wetlands. A message from World Wetlands Day 2015, indicated that many wetlands in Asian countries are connected to rice paddies that have been polluted by various types of pesticides and fertilizers. Although direct application of Persistent Organic Pollutants (POPs) and their metabolites have mostly ceased, many chemicals persist and continue to contaminate all habitats and niches. Currently, threats from modern, sophisticated toxic agents like Neonicotinoids, have resulted in diminished cohort development in birds.
Remediation of toxic pollution in wetlands may be accomplished by phytoremediation, also known as phytoextraction, phytoaccumulation, or phytosequestration. Phytoremediation uses plants or algae to remove contaminants from soil or water into harvestable plant biomass and is important in constructed wetlands. Constructed wetlands recreate the functions of natural wetland plant communities, consisting of a highly diverse mix of grasses, sedges, forbs (broadleaf plants), ferns, shrubs, and trees and, at the same time, act as a filtering agent to remediate toxic pollution.

August 2019: Restoring Lake Apopka – Water Quality, Wetlands, Water, and Wildlife
Restoring Lake Apopka – Water Quality, Wetlands, Water, and Wildlife
Recovering submerged aquatic vegetation and floating-leaf vegetation in Lake Apopka
Sunset over the Lake Apopka North Shore
Lake Apopka, central Florida’s original tourist attraction, has been threatened over the decades by floodplain wetland loss, excessive nutrient and organochlorine pesticide pollution, and multi-year droughts. Since the late 1980s, the St. Johns River Water Management District has been working to address each of these threats to the lake’s health, through wetland restoration, nutrient removal (marsh flow-way system, rough fish harvest, BMPs, etc.), and contaminant remediation. In response, the lake’s water quality and habitat conditions have improved substantially; nutrients decreased, water clarity increased, submerged aquatic beds began recovery, and habitat for fish, birds, and other wildlife has improved. In addition, the recreational usage of the area has been on the rise with the Lake Apopka Wildlife Drive offering visitors an opportunity to see a portion of the recovering wetlands and lake on the formerly farmed north shore of the lake. This talk will cover the lessons learned from past and current restoration efforts and will address planned future efforts to restore this 50,000-acre ecosystem.
Dr. Erich Marzolf is the Director of the Division of Water and Land Resources at the St. Johns River Water Management District, Palatka, FL, where he oversees the Bureaus of Water Resources, Water Resource Information and Land Resources. From 1994 to 2012 he was a District scientist, working on lake, river, wetland and spring restoration projects. In 1999 he began working on the Lake Apopka program as a supervising environmental scientist overseeing portions of the restoration program. Erich earned a master’s degree and Ph.D. in Ecology from the University of California Davis where he studied subalpine lake ecology. Prior to joining the District, Erich was a scientist at Oak Ridge National Laboratory.

July 2019: How to Make Better-Constructed Wetlands
How to Make Better-Constructed Wetlands
Gosforth Valley wetland is owned and managed by Yorkshire Water with the support of Dronfield Town Council and the Lea Brook Valley Volunteers. Innovatively created as a means to control stormwater, its main purpose is to help protect the town of Dronfield from flooding. Designed to store excess water during times of heavy rainfall, it collects water from surrounding urban areas that may otherwise flood. Further development and continuous improvement of the site has enhanced the beauty, amenities and wildlife habitat of the valley for the benefit of the residents and wildlife.
This wetland is very important for the conservation of wildlife within Dronfield and North East Derbyshire and includes many native trees and plants which help to improve the amenity and biodiversity of the site. The habitat has been developed to support wetland bird species such as shoveller (Anas clypeata), grey heron (Ardea cinerea), and snipe (Gallinago gallinago), invertebrates such as the common darter (dragonfly) (Sympetrum striolatum), water boatman (Notonecta glauca) and water flea (Bosmina longirostris); amphibians such as the common frog (Rana temporaria) and common toad (Bufo bufo) and mammals such as the European water vole (Arvicola amphibius).
This site is a great example of how working together through partnering and trust supports community, educational and environmental enhancement. The site enhances biodiversity by maintaining, and also introducing new habitats.
Volunteers work with local conservation groups, the LPC, Yorkshire Water and others, carrying out many activities, such as conserving the local ancient hedgerow, creating a nature trail, providing interpretation boards, tree planting, etc

Aerial view straight down on recently restored southeast ditch, with ditch blocks and borrow pits visible.
A diverse partnership of government, local community, NGOs and private sector partners have worked together for the past 10 years to advance the conservation and restoration of Big Meadow Bog, with the protection of the globally endangered Eastern Mountain Avens (Geum peckii). Historic agricultural ditching and radical changes to surface flows into the bog, coupled with nesting Herring gulls, had led to a precipitous loss of the Eastern Mountain Avens across the bog.
In 2015 East Coast Aquatics Inc. (ECA), on behalf of the partnership and the Eastern Mountain Avens Recovery Team, developed a restoration design for the site to re-establish bog hydrology which would in turn define the restoration trajectory for the larger project. Implementation of the restoration design occurred between 2016 and 2018 in phases and included cutting of trees and shrubs, construction of 123 ditch blocks, re-profiling 3700 meters of the ditches, and re-establishment of open water features locally known as the Lily Ponds and Jimmy’s Pond.
The webinar will address the iterative process used in developing the restoration design, the pitfalls and lessons learned through the construction and implementation phases, as well as the preliminary post-restoration monitoring results. It will also address the very real benefits of meeting and spending time with other wetland practitioners to share knowledge and experiences.
Andy Sharpe is the Projects Manager with East Coast Aquatics, an ecological consulting firm based in Nova Scotia’s Annapolis Valley, Canada. Within this role, he supervises the company’s core services of habitat assessment, ecological inventories, restoration design and implementation, as well as and environmental effects monitoring.

This experience has encompassed work as a government regulator, as an ecological consultant and with community-based watershed groups and NGOs. This breadth of experience has provided him with unique perspective on ecological restoration, its opportunities and challenges. For his role in the design and restoration of the Big Meadow Bog, Andy, with his co-worker Michael Parker, were awarded the Gulf of Maine Council on the Marine Environment Visionary Award in 2018.
April 2019: Evaluation of soil respiration rates across a range of well-pad peatland restoration treatments in the Alberta oil sands region
Evaluation of soil respiration rates across a range of well-pad peatland restoration treatments in the Alberta oil sands region
These are the three different well pad restored peatland sites in Alberta oil sands region. Site (a) is SKEG, (b) is H38 and (c) is IPAD.

Oil sands mining disturbs the carbon sink function of peatland ecosystems. Various restoration techniques have been tested for well-pads in peatlands and rates of carbon exchange can be used to evaluate the return of ecosystem function post-restoration. We measured dissolved organic carbon (DOC) and soil respiration rates (CO2 emissions) in three different restored sites: SKEG, IPAD, and H-38. A total of 13 restoration treatments were studied which included four treatments in SKEG (partial pad removal with planting: dry carex (Carex aquatilis), dry willow, wet carex, wet willow); three treatments in IPAD (peat, clay and mixed inversion); and six treatments in H-38 (complete pad removal: vegetated, soil under open water; partial pad removal: moss, equisetum; partial pad removal: sedgy, non-sedgy). An incubation jar method was used to measure respiration rates in soil samples (collected from the treatments) using an infrared gas analyzer (EGM-4). The soil respiration rates were measured every third day for a total of nine days. Effects of different restoration treatments and their corresponding soil respiration rates were compared. Results were compared to values measured at natural bog - hummocks and hollows in SKEG and fen - hummocks and hollows in H-38. Among various restoration treatments, dry partial pad removal at SKEG showed non-comparable DOC values but similar soil respiration rates as natural sites- In contrast, restoration treatments in H-38 varied significantly from natural sites (p < 0.05). Low DOC concentrations were observed in some mineral dominated sites in SKEG (1.28-4.95 mg/l) whereas, comparatively high values of DOC were observed in some peat dominated sites in IPAD (29.60-75.31 in mg/l), SKEG (36.76-70.77 mg/l) and H-38 (3.673-27.43 mg/l). Soil characteristics (EC, pH, loss on ignition, bulk density) had poor relationships with each other suggesting minimum interplays among them. The results are helpful in selecting effective restoration treatments that return the ecosystem function post-restoration of well-pads on peatland in the Alberta oil sands region.
My specific interests are - water quality index and its seasonal variation in urban wetlands; Carbon and methane fluxes in wetland; Behavior of different forms of phosphorous and nitrogen in sediment cores and water. Stable isotopic systematics. Heavy metal characterization in various components of wetland and their associated potential ecological risk. Use of different isotopic signatures in tracing pollution, and finally wetland restoration and management strategies.
I have a master’s degree in Environmental Sciences. Worked on heavy metal characterization in urban soils of Gurgaon city, Haryana, India towards my M.Phil. degree where I explored various geochemical changes in an urban landscape with changing land use. Currently, I am working on several wetlands of Gurgaon - one of the highly developed cities of India, for water and sediment quality along with nutrient dynamics.

Wetlands in a Changing Climate: Science, Policy and Management
Red-necked avocets in estuarine wetlands in the industrialized Hunter river estuary, Newcastle, Australia by Max Finlayson
Red Maple swamp in Amesbury Massachusetts by Gillian Davies
On October 8, 2018 the Intergovernmental Panel on Climate Change issued a special report for policy and decision makers. They concluded that to avoid exceeding the 1.5o C limit set in the Paris Climate Agreement, the world must reduce net carbon dioxide emissions 45% by 2030 and not exceed removal rates by natural systems by 2050. While addressing the role of forests in meeting this goal, it failed to address the wetland policy and management opportunities that could also contribute to reducing atmospheric concentrations of carbon dioxide. The report also did not note that peatlands and vegetated coastal wetlands are among the most carbon rich sinks on the planet, sequestering approximately as much carbon as do global forest ecosystems. We recently summarized the current and potential climate role of wetlands in a recent paper and an article. Freshwater wetlands and those underlain by permafrost store additional large carbon stocks and provide climate resiliency for ecosystems and society. The current stock of wetland carbon has accumulated over centuries to millennia, but it is being released as these ecosystems are drained, thawed, or disturbed in a matter of months or years. The recent rise in temperature has increased soil respiration rates and thawed permafrost to release additional carbon dioxide and methane to the atmosphere. The time-asymmetry between accumulation and release of heat trapping greenhouse gases makes it essential to protect existing wetland ecosystems and to restore degraded wetlands in an appropriate manner that enhances carbon storage and minimizes methane emissions – an opportunity seldom considered as a climate solution. We will explore the policy and management realms across international, national, subnational and local levels to identify strategies and policies reflecting an integrated understanding of both wetland and climate change science. Specific recommendations will be made to capture synergies between wetlands and carbon cycle management for climate mitigation, adaptation and resiliency and to further enable researchers, policy makers and practitioners to better protect wetland carbon and support climate adaptation and resiliency ecosystem services. The role of organizations such as Society of Wetland Scientists in furthering these goals will also be discussed.

February 2019: Valley-bottom palmiet wetlands: the mysterious peatlands at the tip of southern Africa
Valley-bottom palmiet wetlands: the mysterious peatlands at the tip of southern Africa
A palmiet wetland filling the valley bottom above the Theewaterskloof Dam, in the Western Cape of South Africa
Peatlands are rare in the Cape Floristic Region, located along the south-eastern coast of South Africa, with weather conditions not conducive for the formation of peat. The Cape Floristic Region has a predominantly Mediterranean-type climate characterized by summer drought and winter rainfall resulting from the passage of cold fronts. Mean annual rainfall for South Africa is about 464mm, and in the Western Cape is 323mm, with mean annual A-pan equivalent potential evaporation of around 2230mm. Yet surprisingly, peatlands exist in this region. Notably, valley-bottom palmiet wetlands. Palmiet wetlands are dominated by the wetland plant Palmiet (Prionium serratum), which is a unique species taxonomically, recently moved from its own family ‘Prionaceae’, to ‘Thurniaceae’ (Poales). Palmiet has been suggested to be an ecosystem engineer by some, cited to be the species that was able to stabilize these valley-bottoms originally, and allow sedimentation and eventually the formation of peat (several peat basins have been dated to around 5000-5500 years old). Palmiet wetlands are located in high energy catchments, subjected regular flood events of high force, which would rip out any shallow-rooted species. Palmiet, a deep-rooted clonal species, is highly adapted to this disturbance and therefore is typically flattened by the flood waters, able to recover afterwards.
Palmiet wetland soils and groundwater are naturally oligotrophic with a low pH, largely due to the soils of the Cape Floristic Region being mainly highly leached dystrophic lithosols associated with the sandstone mountains of the Cape Supergroup. As a result of occupying valley bottoms, palmiet wetlands tend to be long and narrow (around 300m across). They are sparsely distributed across the Cape Floristic Region, with around eight significant palmiet wetlands remaining across the region (about 1000km across), remarkably similar in their species composition despite their isolation.
With the arrival of western agricultural practices around 300 years ago, the landscape of South Africa was to change dramatically, with the removal of wetlands, the channelization of rivers, alteration of the natural fire regime and the introduction of invasive alien trees. These changes were to alter the functioning and structure of many wetland systems in South Africa. The structure and functioning of palmiet wetlands are discussed, along with more recent restoration and rehabilitation initiatives, drawing from the research of several South Africans scientists.

The State of Vermont strives to provide and apply the best mapping tools available to protect and restore wetlands throughout the State. Through the Agency of Natural Resource’s Wetlands Inventory Map the State is able to consolidate and provide these layers to their partners and general public. The base of many of these tools is the jurisdictional layer, the Vermont Significant Wetland Inventory (VSWI), that protects wetlands via GIS mapping derived from the NWI dataset. A supplement to the VSWI is the ever-evolving Wetlands Advisory Layer which is continuously amended with non-jurisdictional mapping data derived from regulatory and non-regulatory boots on the ground work; including NWI+ updates, EPA funded bioassessment monitoring, Natural Heritage cataloguing, Program staff site visits, and other governmental and non-governmental wetland mapping projects. The most recent update to this layer will include an NWI layer update for the Missisquoi River to meet NWI+/LLWW standards. This watershed was targeted for revision since it was understood to be under mapped and due to its diverse landscape and mixed land use history.
Along with these mapping layers, Vermont also has a wetland restoration site prioritization model and associated mapping product to target restoration efforts towards meeting our Lake Champlain phosphorus TMDL goals. The original GIS-based Lake Champlain Wetland Restoration Plan is a quantitative prioritization model to rank the potential of land to mitigate P loading to Lake Champlain based on site function and upslope drainage attributes. A recent model update further refined the original output and resulted in the development of potential wetland restoration easement boundaries for targeted landowner outreach.
Julie Follensbee has served as a District Wetland Ecologist with the Vermont Department of Environmental Conservation for 12 years. The position protects Vermont’s wetlands through regulation, education, restoration, and enforcement. As Program Restoration Specialist she reviews potential wetland restoration projects; collaborates with state, federal and non-government organizations; advises restoration bioassessment; and is developing a statewide tracking system for wetland restoration work. Julie has a Master of Science degree in Natural Resources from the University of Vermont’s Rubenstein School of Natural Science. Prior experience includes stormwater management and contaminated sites remediation.
Brock Freyer currently works to protect Vermont’s wetlands as a District Wetlands Ecologist in Vermont Department of Environmental Conservation’s Wetlands Program. In doing so he collaborates with state, federal and non-government organizations by providing regulatory, technical, and moral support. Prior to his work in Vermont, he has bounced around the U.S. wandering in wetland and riverine systems hoping to keep his feet dry in wet spots. No matter where he is working, he is constantly intrigued by the working landscape and how our activities have altered the natural systems present. Through a hydrogeomorphic/landscape scale lens he looks for opportunities to restore and enhance these potentially degraded systems. Brock is a PWS (#2441), has a M.S. degree in Earth Sciences from UNC-Charlotte, and a B.S. in Natural Resource Management from Western Carolina University.
December 2018: Potential climate change impacts on native seeds relative to Phragmites
Potential climate change impacts on native seeds relative to Phragmites
The response of seed germination to future climate change scenarios is an important consideration as climate change will likely exacerbate high mortality rates of seeds and seedlings in the field. Evaluating the response of seed germination under various temperature and water regimes will allow for better predictability in restoration outcomes. Great Salt Lake (GSL) wetlands are a critical resource in the Intermountain West and are globally significant for millions of migratory birds that depend on this habitat. Unfortunately, GSL wetlands are threatened by increasing demands on water upstream for development and agriculture, and the proliferation of invasive species as Phragmites that replaces habitat-forming native plants such as bulrushes. Native bulrushes serve as critical food and nesting sources for migratory birds and are target species for GSL wetland restoration. The study aim was to provide a tool to better predict seed germination of Phragmites and native bulrush species from different regions under current and future climate scenarios. We evaluated seed germination response of Phragmites and three species of native bulrushes to four temperature regimes in growth chambers: 23/10° C (present May), 28/14° C (present June), 33/18° C (present July and also June 2070), and 36/20° C (July 2070), and five water potentials (0, -0.15, -0.3, -0.6, and -1.2 MPa). We compared germination response under these controlled conditions to seeds sown in GSL wetlands, where we monitored seedling emergence during June and July 2018. We found some interesting interactions of temperature and water potential: (1) under the optimal germination temperature for Phragmites, water potential did not matter, (2) bulrush seed germination varied substantially more among the different temperature regimes than did Phragmites, (3) germination lag time was affected more by the water potential change than by temperature for all species, and (4) field germination rates (range 10 - 24%) were lower than germination under simulated climate change conditions in growth chambers. Our findings can support models to organize, interpret, and forecast wetland restoration outcomes, and also it can improve restoration strategies applied in GSL wetlands. This study was part of the SWS Wetland Ambassador fellowship program during summer 2018.

November 2018: Wetlands Of The Coast Of Lima Peru
Wetlands Of The Coast Of Lima: Patterns Of Diversity And Challenges For Conservation
One of the characteristics of coastal wetlands in Lima is that they are very close to urban areas. The photograph shows the Los Pantanos de Villa Ramsar site, one of the most important wetlands in the capital. This wetland is home to hundreds of species and is a resting place for migratory birds.
The coastal wetlands of Lima comprise a coastline that shares the territory with the most populous area of Peru. These conditions make these wetlands have a landscape composed of nature and the different human activities that accompany it. In this context, these wetlands provide different ecosystem goods and services, including carbon capture, the supply of plant fibers, an environment for bird watching and an adequate space for environmental education. To date, in these wetlands have been reported 150 species of birds, 123 species of plants, 11 reptiles, 2 amphibians, 5 rodents and 3 species of bats, 128 species of protozoa, 11 species of snails, 5 rotifers. In the present work, a compendium of information resulting from research carried out in the last 10 years in these marine-coastal ecosystems is presented, taking a landscape perspective to show some patterns of alpha, beta and gamma diversity with greater emphasis on vascular plants. The results obtained to date indicate some interesting features of the components of the landscape: a) the alpha and gamma diversity in Lima's wetlands is intimately linked to the anthropic processes that occur in these ecosystems, generally finding greater diversity alpha and gamma plant in the ecosystems of greater disturbance; b) regional beta diversity is greater in plants than in birds, while the regional richness of species follows an inverse pattern; c) the regional beta diversity is greater than the local one; d) beta diversity is not correlated with distance, which differs from other ecosystems evaluated in the world. An analysis based on the most recent data indicates that between 61% and 85% of the richness of vascular plant species is known, with a potential to harbor between 139 and 193 species in the coastal wetlands of this region. The processes involved in the formation of these patterns and their implications for the management and conservation of these wetlands are presented and discussed.

October 2018: The Ramsar Convention and the Society of Wetland Scientists
The Ramsar Convention and the Society of Wetland Scientists
The Convention on Wetlands is an intergovernmental treaty whose mission is the conservation and wise use of all wetlands through local and national actions and international cooperation, as a contribution towards achieving sustainable development throughout the world. The Convention text was formally concluded on 2nd February 1971 in the city of Ramsar, Iran, hence the informal name ‘the Ramsar Convention’. The vision of the Convention is that all wetlands are conserved, wisely used, restored and their benefits are recognized and valued by all. Countries that are signatories (known as Contracting Parties) commit to delivering on the three pillars of the Convention, namely: the wise use of all wetlands; the designation and management of wetlands of international importance (Ramsar Sites); and international cooperation. The Convention comprises several bodies. The main decision making body is the Conference of the Contracting Parties (COP) where representatives of governments meet to agree on a work programme and budgetary arrangements for the next triennium and consider guidance on a range of ongoing and emerging environmental issues. The main advisory body to the Convention is the Scientific and Technical Review Panel (STRP). The STRP comprises a chairperson, appointed members, representative of each of the six International Organization Partners (IOPs) and National STRP Focal Points from the Contracting Parties. In addition, representatives of other convention secretariats, convention subsidiary scientific bodies, and scientific organizations as officially Invited Observer Organizations, invited experts, consultants, and organizations are asked to participate as required. The Society of Wetland Scientists (SWS) has been formally recognized as an Invited Observer Organization since 1999 and through the SWS Ramsar Section members of SWS have made, and continue to make, a significant contribution to the technical and scientific work of the Convention. This webinar will describe in more detail the work of the Convention, how it is progressing towards its vision, what will be considered at the forthcoming Thirteenth Conference of the Contracting Parties (COP13) to be held in Dubai, United Arab Emirates, between 21st and the 29th October 2018 and how SWS is involved in a variety of Convention processes.

September 2018: Practical Advice for Management and Continuous Improvement in Wetland Restoration
With over 10,000 acres under development and more to come, restoration of the wetlands on the North Slope of Alaska requires a coordinated, comprehensive, and collaborative effort. Oilfield development of Alaska’s Arctic vast coastal plain has been underway for over 50 years and includes construction of industrial roads, airstrips, pads, and pipelines. This infrastructure requires placement of three to five feet of gravel upon the tundra to prevent thawing of the underlying permafrost. With hundreds of tundra rehabilitation sites overseen by regulatory compliance obligations, program management is paramount for success. A successful program requires long-term commitment; program leadership; a strong relationship with primary contractors; an adaptive management approach based on a strong experimental component; owner-sustained support for project planning, implementation, and monitoring; and collaboration with consultants, university researchers, government agencies, and NGOs. Each restoration plan – and subsequent monitoring for performance standards – requires evaluation of the efficiency and value of revegetation and monitoring.

August 2018: Examining interactions among vegetation and water quality in conservation wetlands of the Mississippi Alluvial Valley
It is expected that intensification of agricultural activities will be required as we work to meet the food and fiber needs of an estimated 9 billion people by the year 2050. Unfortunately, intensification of agriculture has the potential to impact the environment via such processes as nutrient and pesticide runoff, erosion, and soil salinization. Wetlands in agricultural landscapes face substantial challenges because of their frequent occurrence immediately adjacent to crops, but they also can serve an important role in mitigating agricultural impacts on downstream ecosystems. For example, wetlands can retain nutrients and sediments that would have been transported to streams, lakes, and nearshore coastal environments, thus reducing impacts of eutrophication and hypoxia in coastal habitats, even when the wetlands themselves are located far inland. Our recent research has investigated the role of wetlands and wetland vegetation in mitigating impacts of agricultural practices, and we specifically have examined the relationship of wetland vegetation to nutrient and sediment contaminants. In our studies of wetlands that have been created or restored through federal conservation initiatives, we found water quality is generally similar to that of nearby non-managed wetlands, wetland species diversity appears to benefit from proximity to other land conservation practices, and plant assemblages of restored wetlands seem somewhat robust to inputs of nitrogen and sediment, within the range of those seen in intensely farmed landscapes. We did, however, find that although wetland plant assemblages generally retain their species signatures in the face of nutrient and sediment stressors, some filtering of species may be observed over time under the highest loadings of these contaminants. Additionally, we propose a tiered approach to better understand the interplay of abiotic factors influential to wetland structure and function in restored systems. Our work has the potential to inform future restoration efforts within agricultural landscapes, which will be a critical need as we look to a future of balancing these efforts while simultaneously meeting increased global demands for food and clean water.

June 2018: Climate Change and Coastal Wetlands: Planning for Resiliency in the Face of a Rising Tide
Climate change is a real and pressing issue facing resource managers, and as such requires planning for the protection of coastal wetland resources. Understanding the ecological trajectory of coastal wetlands that currently are, or in the future will experience effects of sea-level rise and altered temperature regimes, is critical to anticipating future coastal ecosystem form and function. This is highly important in areas where wetlands play a regionally significant role as storage pools of ecologically relevant elements (carbon, nitrogen, phosphorus), critical habitat for fisheries, or provide other desirable ecosystem services.

This is highly important in areas where wetlands play a regionally significant role as storage pools of ecologically relevant elements (carbon, nitrogen, phosphorus), critical habitat for fisheries, or provide other desirable ecosystem services.
We utilize observations of salt water intrusion into the freshwater marshes of the Florida Everglades and the resulting "peat collapse" to provide insight into ecosystem trajectories of vegetation communities and organic soil resources. The synthesis of these observations suggest significant changes to ecosystem form and function within the footprint of salt water transgression, providing resource managers with tools to plan for ecosystem changes. We also utilize observations of mangrove expansion into historical saltmarsh ecosystems on the Atlantic and Gulf Coasts of Florida which indicates climate change, in the form of reduced freezing events, is allowing a shift in foundation species in coastal wetlands. The change of dominant vegetation from marsh cordgrass (Spartina alterniflora) to woody, canopy forming black mangrove (Avicennia germinans) and red mangrove (Rhizophora mangle) can have significant effects on ecological function and ecosystem services provided. We synthesize results of several research efforts in this changing coastal wetland system to provide resource managers and research scientists alike with ecosystem trajectories which include alterations to blue carbon storage, habitat value, and trophic structure. These trajectories form the basis for which to forecast change and resiliency in coastal wetlands and plan for protection of high value wetland resources.

November 2017: Wetland Restoration in the Rocky Mountains, USA: Lessons from the Field
During this webinar, I’ll describe several recent wetland restoration and compensatory mitigation projects completed in the Great Plains, Western Mountains and Valleys, and Arid West Regions of the western US. Each project presents its own challenges and offers its own lessons. These vary from specifics of restoration design and planting techniques, to the nuances of regulatory compliance and performance standards. I'll present various methods and approaches that have resulted in many successfully completed projects over the last 19 years.
Andy Herb, owner of AlpineEco (founded in 2007), has worked as a professional ecologist for 19 years. Although most of his work has been in the western USA, he also has successfully completed many projects in the Republic of Korea, Japan, and Guam. His work involves most aspects of field ecology, with a focus on wetland and vegetation studies. He has been involved in many projects that included Clean Water Act (Section 404), National Environmental Policy Act, and Endangered Species Act compliance, as well as general natural resource management. Mr. Herb has lead both research-oriented and infrastructure-related work for nearly all types of clients in the private and public sectors, including dozens of projects involving wetland creation and restoration. He is the immediate past-president of the Rocky Mountain Chapter of the Society of Wetland Scientists, and is also the founder and chairperson of SWS’s Wetland Restoration Section. His commitment to science and the environment, combined with his practical approach to problem-solving results in creative, cost-effective, and ecosystem-friendly approaches to projects. Mr. Herb is also the owner of AlpineEco Nursery (founded in 2012) which provides native wetland and riparian plants for ecological restoration in the Rocky Mountain Region.
April 2018: Peatlands, Parks, and Playas: a Tour of Colorado’s Diverse Wetlands
Colorado is known for its high mountain peaks and river valleys, but its geography is far more diverse than its reputation suggests. The eighth largest state in the country, Colorado covers over 100,000 square miles (270,000 km2) stretched across three main ecoregions: high plains to the east, peaks and valleys of the Rocky Mountains through central Colorado, and canyons of the Colorado Plateau to the west. Colorado’s elevation range spans more than 10,000 feet, from just over 3,300 ft (2,070 m) along the eastern border with Kansas to 14,440 ft (4400 m) at the top of Mount Elbert, and its geology includes diverse metamorphic, volcanic, and sedimentary formations. The canvas of Colorado’s geography creates a rich and diverse array of wetlands, though the semi-arid climate limits the extent of wetlands to less than 2% of the state’s land area.
The Colorado Natural Heritage Program (CNHP) at Colorado State University has been cataloguing, classifying, and assessing the condition of Colorado wetlands for over 20 years. This presentation will introduce listeners to the major wetland types of Colorado and how they fit into the complex landforms of the state. Three major wetland types will be highlighted to tell the story of Colorado wetlands and their origins, the functions they provide, and how they are influenced by past and present land and water use. The first will be groundwater-fed peatlands, or fens, which occur almost exclusively above 8,000 ft and provide habitat for a host of state and globally rare plant species. The second will be expansive wet meadows within the state’s mountain valleys, locally referred to as parks. Today’s wet meadows are closely connected to the intricate water supply and irrigation network that makes life in the high desert possible. The final wetland type will be ephemeral playas and other wetland types of the eastern plains, which are critical for the seasonal migration of millions of birds. Information in the presentation will draw on a variety of studies conducted by CNHP and partner organizations over the years. Get ready for the upcoming SWS Annual Meeting in Denver, Colorado, by learning about wetlands in this diverse and fascinating state!
Joanna Lemly is a Wetland Ecologist at the Colorado Natural Heritage Program (CNHP) at Colorado State University, where she oversees CNHP’s work on wetland assessment and mapping. Under Joanna’s leadership, CNHP is working with Colorado Parks and Wildlife (CPW) to assess the condition and habitat quality of Colorado’s wetlands, one river basin at a time. The assessments employ field protocols developed by CNHP and CPW to assess both general condition and the quality of habitat available to priority wetland-dependent wildlife species. Since 2008, Joanna and colleagues at CNHP have worked closely with the U.S. Fish and Wildlife Service’s National Wetlands Inventory to create a statewide digital map of wetlands. Their most recent effort is to add functional attributes to wetland mapping in order to summarize and analyze the functions provided by wetlands on a watershed basis. CNHP has also developed an online mapper to view wetlands data and CNHP is currently working on a more interactive mapping tool to aid with watershed planning. Additionally, Joanna has been heavily involved in the development of both online and printed educational resources for wetlands, including the Field Guide to Colorado’s Wetland Plants and the Colorado Wetland Information Center (www.cnhp.colostate.edu/cwic). Joanna has worked in various aspects of plant ecology for over 15 years, with a particular emphasis on wetland ecology. She holds an M.S. in Ecology from Colorado State University, a Certificate in Wetland Science and Management from the University of Washington, and a B.A in Environmental Science from the Colorado College.
March 2018: Livestock grazing affects microbial activity at different soil depths via the groundwater level with potential implications for carbon sequestration
Saltmarshes, as many other wetlands, provide various ecosystem functions and services including shoreline protection and carbon (C) sequestration. The salt marshes of the Wadden Sea (Germany), have been strongly altered by anthropogenic influences such as livestock grazing, which has been practiced for centuries. It is, however, unclear how grazing affects some ecosystem functions and services. Carbon sequestration, for example, might be affected by livestock grazing both positively and negatively. On the one hand, grazing will reduce aboveground biomass, but was also previously found to increase belowground biomass, which is likely contributing more to soil organic C. On the other hand, livestock grazing can alter soil properties by soil compaction leading to lower pore space. This could lead to a reduced water drainage and thus a reduced Oxygen availability, which in turn hampers the breakdown of organic material by microorganisms. Therefore, the aim of this study was to assess the effect of grazing on soil structure and its influence on hydrology in salt marshes of the Wadden Sea. Additionally, we aim to quantify microbial activity as a proxy for the decomposition of organic matter at different soil depths. Our hypotheses were that soil at the grazed saltmarshes would have higher soil bulk density, lower C content, and lower water drainage rate.
Two saltmarshes were selected at the coast of the Wadden Sea: Dieksanderkoog marsh (DSK) and Sönke-Nissen-Koog marsh (SNK). Both DSK and SNK are part of the Schleswig-Holstein Wadden Sea National Park, Germany. With the establishment of National Parks in the 1990s, livestock grazing was abandoned in large areas. To study the effect of this grazing reduction on vegetation, two experiments were established at DSK and SNK in 1992 including a grazing treatment with sheep and an ungrazed control treatment at both sites. To assess the impact of grazing on soil properties in this experiment, a total number of 8 undisturbed soil cores (20 X 50 cm) were collected by inserting sharp edges PVC pipes in October 2017. The soil cores were scanned in collaboration with Dr. Jürgen Titschack (MARUM Bremen) using a Computer Tomograph (CT) at the hospital Klinikum Bremen-Mitte, Germany, with an x-ray source voltage of 120 kV and a current of 600 mA. Following the soil CT scan and side-opening the cores, soil sub-samples were taken; where soil bulk density (g cm-3) and total C content (%) were estimated by core method and CHN analyses, respectively. Water level for both sites was recorded every 5 minutes for the last two years using slotted PVC wells and pressure sensors.
Data analyses of the cores indicated that ungrazed salt marshes have higher porosity (i.e. the percentage of pore spaces relative to sediment material) and connectivity (i.e. the ratio of number of disconnected pores relative to the total pore volume per slice) compared with grazed sites. Additionally, sediment density was higher at the grazed sites and increased with soil depth. Furthermore, the soil sub-samples results indicated that grazing had an impact on soil properties with higher soil bulk density and lower C content, most noticeable in the upper 5-10 cm. In line with this result, monitoring of water level indicated faster drainage rates for the ungrazed marshes as a result of higher porosity and less compaction. Furthermore, we expect that the longer retaining of the water between soil particles as a result of soil compaction by trampling might also impact the soil microbial activity. This parameter will therefore be assessed in soil cores from the same site in spring 2018.

February 2018: The enigmatic Okavango Delta: A large wetland in a dryland
The Okavango Delta, with an area of approximately 15 000 km2 (almost 6 000 square miles), is southern Africa’s largest wetland. Remarkably, it is situated in the Kalahari, which is semi-arid with a mean annual rainfall of around 500 mm (20 inches), while mean annual potential evapotranspiration is well over 2 000 mm (80 inches). As such the Okavango is a wetland in a dryland landscape as it is characterised by a strongly negative water balance.
Runoff from rainfall in the highlands of central Angola drains south-eastwards into the Kalahari Basin, such that it disappears within a continental setting and never reaches the ocean. Of the water entering the Okavango via runoff and rainfall, 98 % evaporates. All of the clastic and 98 % of the dissolved sediment transported into the ecosystem is deposited within it. The accumulation of dissolved sediment in the ecosystem should lead to salinization of surface waters, but the ecosystem is characterised by fresh surface waters that are crystal clear.
Deposition of clastic sediment in upper channels leads to large-scale diversion of water from one part of the system to another over timescales of centuries. These events lead to combustion of peat deposits in peat fires that burn for decades. Dissolved sediment that is potentially toxic to the wetland ecosystem as carbonate salts of mainly calcium, magnesium and sodium, accumulates beneath islands where dense broadleaved evergreen forests act as water pumps and draw down the water table. Trees are selective in their uptake of dissolved salts and exclude those that are detrimental to plant and animal life. These salts therefore accumulate in island soils, creating topographic relief. Sodium remains in solution throughout the evaporation process and poisons island soils over timescales of about 100 years. The focussing of potentially harmful salts on islands means that surface water in the wetland remain remarkably fresh. Channel switching leading to changing flow patterns allows renewal of poisoned island soils and the long-term maintenance of a freshwater wetland ecosystem where one might expect salinization.
The structure and functioning of this remarkable ecosystem are discussed in the light of research over a period of about 25 years by a fairly small group of researchers.
Fred Ellery has repeatedly said that there is nothing he would rather do than wander through and think about a wetland. His curiosity and enthusiasm about these ecosystems are epitomised in his research, teaching and learning over the length of his career.
As a young scientist he and his wife Karen worked in a remote part of the Okavango Delta in northern Botswana, an arid country north-of South Africa. As part of a fairly small multidisciplinary research team he learned to think across temporal and spatial scales, and to integrate research findings to develop understanding that he felt was essential if wetlands were to be wisely managed and conserved. More recently he worked in wetlands in the Greater St Lucia Wetland Park in northern KwaZulu-Natal in South Africa. He also headed a research program that addressed issues related to wetland rehabilitation in South Africa, where the state substantially funds wetland restoration nationally through an expanded public works program. Since moving to Rhodes University in the Eastern Cape Province in South Africa about a decade ago, he has worked on smaller wetlands, particularly those occurring on an ancient erosion surface where wetlands are tens of millions of years old.
Fred is well known nationally and has international links with scientists in Australia, Europe and North America. He is currently a joint Chairperson of the International Chapter of SWS, with responsibilities in promoting the activities of the Society in Africa.
January 2018: Blue Carbon: Science and Application for Adding Value to Estuary Restoration
Coastal blue carbon has emerged as new opportunity to connect coastal management goals with climate mitigation and adaptation. Degradation and destruction of coastal blue carbon ecosystems (salt marshes, seagrass meadows and tidal forests) results in the loss of many important ecosystem services, including carbon storage and sequestration. Protecting and restoring these ecosystems can prevent CO2 emissions, increase carbon sequestration, and also reduce emissions of nitrous oxide and methane.
In the past few years, much has been achieved to advance the science and policies related to blue carbon at global, national and locally scales. Networks of NGOs with state, federal and private partners are leading the way in advancing our understanding of blue carbon science and piloting blue carbon application in management, policy and markets. This presentation will cover past and ongoing science assessments led by Restore America’s Estuaries (a US based non-profit) and our partners, tools and resources for applying blue carbon, and discuss remaining science needs.
As blue carbon initiatives have been growing over the past few years, this talk will also include existing and emerging networks, in the US and globally, working to advance blue carbon for coastal conservation. This ecosystem service provides an opportunity to add value for coastal restoration and conservation efforts, enhance habitat management to include climate adaptation and mitigation, and tap into carbon finance.
Stefanie Simpson is the Blue Carbon Program Senior Manager for Restore America’s Estuaries, where she works to build regional and national capacity for utilizing blue carbon ecosystem services to increase investment in coastal restoration and conservation. In this role, Stefanie develops outreach products, leads the US Blue Carbon National working group, and works with partners to develop tools and pilot projects utilizing blue carbon to support estuary restoration. Prior to RAE Stefanie was an ORISE Fellow for the EPA’s Office of Water, worked at the ACE Basin National Estuarine Research Reserve in South Carolina, and served as a Peace Corps Volunteer in the Philippines promoting environmental stewardship and working with locals on coastal resource management. Stefanie has her B.S. in biology from Clemson University and a M.S. in Environmental Studies from the College of Charleston.
December 2017: Five Causal Factors: A General Framework for Wetland Science and Restoration
At one time, lack of information limited our understanding of wetlands, and made restoration difficult. Now it is possible that the opposite is true: we are drowning in data on wetlands, and confused about how to best apply the huge volume of information. People are now, it seems, busily engaged in collecting data that no one will ever use, and writing papers that no one has the time to read.
How to deal with this situation? We cannot organize our information by species, because there are too many of them (ca. 125,000 species in wetlands according to the IUCN). We cannot organize information by geographical or ecological region, because there are too many of those too (867 ecoregions according to WWF). Meanwhile, new data streams into journals. What is to be done?
Perhaps we can learn from others. Consider that physicists can describe most of the universe using only four forces! Without succumbing to physics envy, we could borrow from this approach, and consider causal factors as ecological forces that transcend species and geography. Causal forces might provide us with a set of general principles to organize our existing knowledge, and to guide our attempts to restore wetlands.
I will explore how only five causal forces may account for nearly all the variation we see in and among wetlands: hydrology, fertility, natural disturbance, herbivory, and competition. In fact, the list can be shortened to four if we treat herbivory as just another kind of natural disturbance. These factors operate in all wetlands, be they peat bogs, mangrove swamps or freshwater marshes. The order in which we list them above matters, since hydrology alone likely accounts for half the variation (ca 50 percent), with fertility and natural disturbance next (ca 15 percent). If we can explain 80 percent of the composition and function of wetlands with just three causal factors, that is actually a rather good situation to be in.
Of course, other factors influence wetlands. Near the coast, salinity needs to be added to this list. Other factors can include burial, roads, and coarse woody debris.
In this presentation, I will walk you through this approach in more detail. My intention is to illustrate each of the causal factors with two examples: one that illustrates generality (for scientific organization of our ideas) and the other that illustrates application (for immediate use in wetland conservation or restoration.)
Dr. Paul Keddy has been a biologist, writer and scholar for more than forty years. He was a professor of ecology at three different universities, and now is an Independent Scholar, living on the edge of a large wetland, deep within the deciduous forests of Lanark County in southern Canada. He has written over 100 scholarly papers, and even more essays, most of which can be found at his web site www.drpaulkeddy.com. He achieved international designation as a Highly Cited Researcher, has awards from the Society of Wetland Scientists and the Environmental Law Institute, and, locally, is designated a Champion for Nature. His best-known books include Wetland Ecology, and Plant Ecology, both of which offer a global perspective on general principles in ecology and their applications to conservation. He also co-edited The World’s Largest Wetlands. In his spare time, has written two self-published natural history guides, one for Lanark County (which won the W.E. Saunders award from Ontario Nature), and one for Louisiana. The focus of his career has been upon the general principles that organize ecological communities, with emphasis upon plants and wetlands. His focus on plants was a rational decision -- the inescapable fact that more than 90 percent of the biomass on Earth is comprised of plants. He has a particular soft spot for turtles, frogs and alligators, but says that getting the vegetation right is essential to provide habitat for such species. He thinks that science should be used to solve problems in the real world, and hence has spent many hours advising on wetland conservation in areas including Nova Scotia, the Great Lakes watershed, and coastal Louisiana, with lesser forays including San Francisco Bay and the Everglades. He has served organizations including the National Science Foundation, the Natural Sciences and Engineering Research Council of Canada, World Wildlife Fund, and The Nature Conservancy. He also puts his money where his mouth is – over 40 years he has slowly bought nearly a square mile of forest and wetland in Lanark County, habitat which has now been donated to the local land trust as a nature sanctuary. He continues to write and lecture. His latest book is a new edition of Plant Ecology. His lectures have included Washington, Toronto, Madrid, Granada, and Lyon — as well as Perth, Almonte and Lanark Village.
Classification of macro-habitats: A powerful tool for comparative studies, sustainable development and environmental impact analysis in wetlands
The Classification of macro-habitats: A powerful tool for comparative studies, sustainable development and environmental impact analysis in wetlands was presented by Prof. Dr. Wolfgang J. Junk from the National Institute for Science and Technology in Wetlands (INCT-INAU), Federal University of Mato Grosso (UFMT), Cuiabá, Brazil.

October 2017: Marsh response to sea level rise: examples from the Chesapeake and beyond
This presentation will focus on how marshes respond to sea level rise, and consider the processes that maintain marshes (i.e. vertical accretion), destroy marshes (i.e. erosion), and create marshes (i.e. migration into uplands). The presentation will particularly draw upon historical and modern examples of coastal change in the Chesapeake region, which includes locations where sea level rise has led to catastrophic marsh loss but also locations where marshes are getting bigger. Central themes include the importance of mineral sediment supply, and the role humans play in allowing or prohibiting marsh migration into adjacent uplands.
Dr. Matthew L. Kirwan is an Assistant Professor at the Virginia Institute of Marine Science with expertise in coastal geomorphology and ecology. His research focuses on marsh response to sea level rise, carbon-climate feedbacks, and the role humans play in the formation and survival of coastal landscapes. He is a graduate of the College of William and Mary and Duke University, and a member of the Nause Waiwash Indian tribe.
September 2017: Subtropical wetlands: comparing primary producer diversity and dominance and addressing restoration challenges
In this webinar, I will present highlights of my recently published research on patterns and controls of algal richness in the Okavango Delta (Botswana) and the Florida Everglades (U.S.A.), and of algal dominance in the Everglades. I will also introduce some preliminary comparisons of restoration approaches in other subtropical wetlands. Globally, anthropogenic activities are heavily impacting subtropical wetlands, for example via hydrological and nutrient changes. In these ecosystems, hydrological variability and nutrient availability are key factors determining changes in the community structure of key aquatic primary producers, such as microalgae. Highly diverse communities may use limiting nutrients more efficiently than less diverse ones, while, in the latter, a few algal species may dominate aquatic primary production. In turn, algal diversity and/or dominance may enhance wetland resilience via food web dynamics; thus we need to address the fundamental question: “How do diversity, enhanced by numerous rare species, and/or dominance by a few well adapted species vary with hydrological and nutrient changes in subtropical wetlands?” To predict how primary producer community structure will change with scenarios of oligotrophication / eutrophication, drying / wetting, and water flow diversion / restoration, we need more comparative studies with standardized approaches, and international and interdisciplinary collaborations. As key challenges await these aquatic systems facing present and/or predicted intense exploitation by humans and global environmental change, how can impacted wetlands be restored to an ecologically sustainable functioning state via effective science, monitoring, management, conservation, and policy?
Dr. Luca Marazzi holds an MSc in Environmental Sciences from the University of Milano Bicocca (Italy) and a Ph.D. in Freshwater Ecology from University College London (UK). Since January 2015, he has been working as a postdoctoral associate in Dr. Evelyn Gaiser’s laboratory at Florida International University, where he is investigating how and why diversity, abundance and biomass of freshwater microalgae change across space, time and environmental gradients in subtropical wetlands such as the Everglades and the Okavango Delta. His previous studies and research, teaching and consultancy work in Europe focused on topics such as bird migration, air quality assessments, climate change scenarios, biodiversity and ecosystem services, and sustainability. He is interested in further developing his comparative studies to encompass the analysis of wetland restoration and conservation practices in collaboration with other wetland experts.
August 2017: Robust Interpolation of Water Levels and Ecological Conditions at Unmonitored Wetlands using Regression-kriging
Tampa Bay Water, Florida's largest wholesale water supplier, is assessing environmental recovery of wetlands and lakes in the Northern Tampa Bay area in response to regional groundwater production cut-backs. Groundwater production cut-backs were initiated in 2003 to improve regional aquifer levels and wetland hydrology and as part of a larger effort to develop diverse, environmentally-sustainable supplies that could accommodate future growth. Over 400 monitored wetlands and lakes are being assessed in comparison to hydrologic standards based on regulatory minimum level criteria. Unfortunately, water level data are unavailable for 684 unmonitored sites (7,900 acres) located in the vicinity of groundwater wellfields, causing uncertainty regarding the extent to which these areas have recovered. We implemented a robust regression-kriging (RK) interpolation approach using R to provide estimates of water level and ecological recovery at each unmonitored site. Best subsets multiple linear regression with the Bayesian Information Criterion was used to select the most probable, but parsimonious, subset of variables for prediction of median water levels relative to indicators of historic inundation for the period 2008-2014. Residuals showed spatial autocorrelation, so they were kriged to generate a combined RK model. Cross-validated residuals from the RK model ranged from -0.66 feet to +0.40 feet for 80% of the locations. The RK predictions were compared to wetland-type specific thresholds to yield recovery status for each unmonitored site. Similar methods were applied to a field-assessed metric of ecological condition available from over 800 locations. The interpolated estimates of both water levels and ecological conditions are being used to screen out recovered sites and prioritize others for further study and potential mitigation.

July 2017: Types of constructed wetlands for wastewater treatment
Constructed wetlands have been used for wastewater treatment since the 1960’s. The first installations were put in operation in Germany; however, at present this technology is used across the globe. Constructed wetlands can be classified according to a) presence or absence of water on the surface (surface and subsurface flow), b) flow direction (horizontal, vertical) and c) according to the type of vegetation used. Constructed wetlands can be used to treat municipal, industrial and agricultural wastewaters, as well as for treatment of storm water runoff from urban areas, agriculture, roads and highways, golf courses, nurseries and for landfill leachate and mine drainage.
Jan Vymazal graduated from the University of Chemistry and Technology Prague where he also received his Ph.D. degree. Currently, he is a professor in the Environmental Sciences department at the Czech University of Life Sciences Prague.

May 2017: Using sediment enhancement to build tidal marsh resiliency on Blackwater National Wildlife Refuge, Maryland, USA
Located in Maryland, USA, Blackwater National Wildlife Refuge is part of the largest area of tidal marsh within the Chesapeake Bay watershed, and is of regional ecological significance for its wetlands and for the wildlife populations it supports. However, over 5,000 acres of tidal marsh have converted to open water on the refuge since 1938. The mechanisms contributing to Blackwater’s tidal marsh loss are generally attributed to a combination of sea level rise, subsidence, and herbivory by nutria.
In many areas on the refuge the elevation of the marsh surface is low relative to local tides, leading to excessive inundation. More than 80% of elevation points recently surveyed on Blackwater NWR were found to be well below the elevations needed for optimum plant growth for the refuge’s tide range (Kirwan and Guntenspergen 2012). When marsh vegetation is at an elevation below that which is optimal for plant growth, the rising sea level will further inhibit root zone growth and lead to additional marsh loss. On Blackwater NWR, vertical marsh development is particularly dependent on organic accretion driven by below-ground biomass production (Cahoon et al. 2010).
In December 2016, 26,000 cubic yards of sediment was pumped in a thin-layer application over approximately 40 acres of tidal marsh on the refuge. The purpose of this project is to raise the elevation of the existing marsh platform. The sediment enhancement will offer a twofold ecological benefit to marsh resilience: 1) The longevity of the marsh receiving thin layer sediment application will be extended by virtue of the raised surface elevation in relation to the tidal regime; and 2) Root zone production, and consequently rates of vertical accretion, should increase. Root zone production is the main driver of vertical accretion rates in the Blackwater River system (Cahoon and Guntnerspergen 2010). Building the marsh platform to an elevation that maximizes plant productivity will take full advantage of the capacity of the marsh to continue to build elevation (Kirwan and Guntenspergen 2012).

April 2017: The Clean Water Rule: Real Facts
The US Environmental Protection Agency (USEPA) and the US Army Corps of Engineers (USACOE) published the “Clean Water Rule: Definition of “Waters of the United States” in 2015 to provide clarification on which US water bodies and wetlands are “Waters of the United States” (WOTUS) and thus, regulated jointly by the USACOE and USEPA under Section 404 of the Clean Water Act. The Clean Water Rule developed from several iterations of clarification memoranda that followed United States v. Riverside Bayview (1985), Solid Waste Agency of Northern Cook County (SWANCC) v. U.S. Army Corps of Engineers (2001), and most importantly, Rapanos et al. v. United States (2006). The rule contains eight categories of water bodies and wetlands and extensive definitions and exemptions to clarify which water bodies and wetlands are WOTUS and which are not. The exemption list formalizes in one source exemptions from various US Federal laws and policies. In this webinar, I will discuss the eight categories of WOTUS, their scientific bases for inclusion, the specific conditions required of each and the exemptions and common misinterpretations. The fate of the Clean Water Rule has been in US national news since January. The Rule is currently stayed nationwide by the US Sixth Circuit Court of Appeals.

November 2016: Reclaiming, Using and Protecting Wetlands: the Dutch Approach
The Netherlands is the common delta of 3 major rivers. Originally a vast expanse of salt marshes, floodplains, swamps and large bogs, the Dutch started to live there on dwelling mounds 2000 years ago. From the 11th century, farmers and monasteries joined forces to build dikes, culminating in large reclamations funded by merchants and noblemen in the 17th century. Only in the 20th century, wetland protection became an issue, while new wetland areas are being created since 25 years. This story is about the vast original wetland wilderness, the ways the Dutch reshaped it into their minutely controlled country, about major floods and continuous innovations in ways to control or make use of wetlands. It ends with the current status, which includes a movie trailer on the Oostvaardersplassen, a vast wetland wilderness of only 40 years old.
Jos Verhoeven is professor emeritus of landscape ecology at the Department of Biology of Utrecht University, The Netherlands. He is also a Research Associate of the Smithsonian Institution in Washington, USA.

March 2017: The Challenges and Successes of Incorporating Coastal Wetlands into the U.S. Inventory of GHG Emissions and Sinks
Land use accounts for about a quarter of anthropogenic greenhouse gas (GHG) emissions, globally, and offers significant mitigation potential. There are linkages with adaptation and food security. Inclusion of land use is a topic of interest in the development of international climate agreements and is essential to meet the goal of avoiding dangerous tipping points of climate change.
It is estimated that, globally, drainage and excavation of mangrove, salt marsh and seagrass wetland soils release 450 million tons of CO2, annually (range 150-1005 MtCO2/yr). This is an emission roughly equivalent to that of California, but is an incomplete estimate as it does not recognize all human impacts to coastal wetlands (e.g. increased CH4 emissions from impaired tidal drainage and release of CO2 with anthropogenically driven wetland erosion).
The U.S. Inventory of GHG Emissions and Sinks (Inventory) chapter on land use, “Land Use Change and Forestry (LULUCF),” reports carbon stock change and emissions of CH4 and N2O, with activities on and conversion between forest lands, croplands, grasslands, settlement and wetlands. With the release of the 2013 IPCC Supplement to the 2006 IPCC Guidelines for National GHG Inventories: Wetlands (Wetlands Supplement), the United States is seeking to include emissions and removals with management activities on coastal wetlands and is responding to a request by the United Nations Framework Convention on Climate Change (UNFCCC) for Parties to report back in March 2017 on experience in applying the Wetlands Supplement.
To support the EPA, NOAA and Restore America’s Estuaries (RAE) have formed an interagency and science community, Coastal Wetland Carbon Working Group (CWCWG). The task of the CWCWG is to conduct an initial IPCC Tier 1 to Tier 2 baseline assessment of GHG emissions and removals associated with coastal wetlands using the procedures described in the recently released IPCC Wetlands Supplement. These initial efforts have assisted EPA with incorporating some preliminary results into the 2016 submission of the U.S. national GHG inventory as an information item, with the goal of full reporting in the 2017 submission. We will report on an update of current activities in support of that goal.
Steve Crooks, Ph.D., is a founder and Principal at Silvestrum Climate Associates, working on integrated climate adaptation and mitigation in coastal areas.

February 2017: Liquid Assets: Building and Sustaining a State-Based Aquatic Ecological Restoration Program
Learn how Massachusetts created the first-in-the-nation, state-based, aquatic, ecological restoration division. With a focus on aquatic ecosystems, DER actively manages over 60 physical restoration projects. Restoration techniques include dam removal, culvert replacement, fill removal, urban river revitalization, water conservation and stream daylighting. Since 2012, DER has leveraged almost $20 million in non-state funds and nearly a $25 million in volunteer assistance. DER and partners have removed 43 dams, providing hundreds of miles of river continuity, and restored over 1,500 acres of coastal wetlands.
This webinar will highlight project successes, including the largest Atlantic white cedar swamp restoration in the Northeast (Eel River, Plymouth, MA) and other complex river and wetland restoration projects.
DER provides a template in how to create, tailor and promote a government-sponsored, ecological restoration program. A description of the tools that have been most effective in attracting and leveraging limited, state funding will also be discussed.

January 2017: Restoring the River Flows
River flows have been recognized as the key driver of freshwater biodiversity by many ecologists. However, the understanding of such an important driver by the public, the industry and policy-makers is very limited. This presentation explains the importance of river flows and the key challenges, and shares WWF’s works in maintaining and restoring river flows, where possible, through tactics including: understanding and assessing environmental flows, restoring the river connectivity, managing and re-operating the existing infrastructures, promoting integrated basin planning and mainstreaming environmental flows into national and global policies.
Dr. Li was the Director of WWF Global Freshwater Program from 2008-2016 and led WWF’s works on freshwater conservation in many of the world’s large rivers, including the Amazon, Rio Grande and Rio Conchos, Amur, Yangtze, Mekong, Ganges, Indus, Danube, Balkan rivers and Zambezi. He has been working on water and river basin management in WWF since 2002 and was the leader of WWF’s work on basin management in China and restoration in the Central Yangtze.
December 2016: Life in the Mud: Relevance to Food Security, Climate Change, and Water Quality
Freshwater wetlands, coastal wetlands, benthic sediments of lakes, rivers, streams, marine sediments and paddy soils, all have one thing in common: mud. Many biological communities use mud as their habitat to support their livelihood. These include microbial communities, invertebrates and plant communities. Typically, mud in these ecosystems is present under water and very little or no oxygen is present in the mud to support their respiration. In this presentation, I will present key of roles of little players, i.e., microbial communities playing large roles in regulating various ecosystem processes that may have a direct link to global food security, water quality and climate change. For example, for the role of mud in food security, I will present global examples of how rice production is mediated by biogeochemical processes, regulated by various microbial communities housed in paddy soils. Similarly, I will provide various examples of the importance of mud in various ecosystems, as related to water quality, carbon sequestration and greenhouse gas emissions.

September 2016: Highlights and Overview of the 2011 National Wetland Condition Assessment (NWCA) and Upcoming 2016 NWCA
Highlights and Overview of the 2011 National Wetland Condition Assessment (NWCA) and Upcoming 2016 NWCA presented a summary of the methods and findings of the first national assessment of wetland condition and a preview of the 2016 assessment. The NWCA is part of U.S. Environmental Protection Agency’s (USEPA) National Aquatic Resource Surveys, and is conducted every five years by the USEPA and its federal and state partners. The survey design allows extrapolation of results to national and regional scales, while chemical, physical, and biological measures are used to measure wetland condition and stressor extent. The results of the 2011 assessment and all NARS surveys are presented in a report available to the public. The webinar was presented by Mary E. Kentula, who is a wetland ecologist with the USEPA’s National Health and Environmental Effects Laboratory’s Western Ecology Division and the technical lead for the NWCA.

Mary’s research within the Program focused on the use of restoration techniques in wetland management. Among Mary’s publications from that work is the book, Wetland Creation and Restoration: The Status of the Science, which she co-edited with Dr. Jon Kusler in 1990. Mary’s current work supports the EPA’s National Aquatic Resource Surveys through the development of approaches to monitor and report on the ecological condition of wetlands. Among her awards, the Society of Wetland Scientists recognized Dr. Kentula with the Merit Award in 2007 for her work in assessing wetlands at the watershed scale. This was followed by the successful completion of the 2011 National Wetland Condition Assessment (NWCA). Mary’s research team led the production of the field operations manual used in the assessment, played a major role in data analysis and reporting, contributed to the final report and wrote the technical report. The technical report details the analysis used in the NWCA. The team is currently providing technical support for the 2016 assessment.
August 2016: Status and Trends of Wetland Restoration
The practice of wetland restoration and our understanding of wetland science has evolved significantly over the last 50 years. However, numerous studies have documented the shortcomings of wetland mitigation and voluntary restoration projects to achieve stated goals. In 2013, the Association of State Wetland Managers began to identify some barriers to wetland restoration and established a Work Group of 25 restoration experts, including practitioners, academics, consultants, regulators, and policy makers, to further identify and analyze these barriers and develop recommendations to address them. There is general agreement among restoration professionals that the science exists to achieve restoration goals and that wetland restoration performance will improve if certain barriers are addressed. Climate change has heightened the interest in using wetland restoration as a tool for mitigation and adaptation and thus the goals and designs for wetland restoration have become more complex and diverse. Although there is no "cookbook approach" for wetland restoration, there are concrete steps we can take to improve restoration outcomes. This presentation will discuss the findings of the Association of State Wetland Managers and its Wetland Restoration Work Group including recommendations from its draft white paper, "Wetland Restoration: Contemporary Issues & Lessons Learned."

November 2015: Wetland Restoration & Management in a Future of Changing Climate
The nature of future climate change will dictate avenues of successful wetland restoration and management. The Intergovernmental Panel on Climate Change (2014) suggests that future wetland environments may have high levels of water availability (extreme drought and flooding), temperature and CO2. Unfortunately, not enough information is available for near-future restoration planning on the potential responses of wetland species to climate change environments. Along sinking coasts, especially freshwater wetland species may be impacted by increased salinity intrusion, flooding, and hurricane activity. Increasing human demand for freshwater may have a major impact on both inland and coastal wetlands. Some recent research has examined minimum flows of water necessary to maintain function of riverine wetlands. For example, studies along the Mississippi in LA USA and Murray River in Australia suggest that even short periods of freshwater release could be beneficial to freshwater trees in hydrologically-altered estuaries. More research directed toward solutions to climate-induced problems may help managers develop approaches to vegetation stress in future restored and natural wetlands. Another idea that may need reconsideration is that of the reestablishment of presettlement conditions, which may be an unattainable target for restoration in climate change environments. Current day attention to potential future environments in wetlands may yield more successful restoration efforts for the future.

May 2016: Structural and Functional Responses of Coastal Wetlands to Changes in Mangrove Cover
Global changes are causing broad-scale shifts in vegetation communities worldwide, including in coastal wetlands where mangrove stands are increasing their range and displacing salt marshes. Coastal wetlands provide valuable ecosystem services including: habitat and food web support, buffering coastal areas from storms and sea level rise and filtering water. Coastal wetlands also store more carbon per area in their soils than other ecosystems, making them globally important “blue carbon” sinks. Changes in carbon storage rates based on vegetation shifts may represent important feedbacks to climate change and since changes in soil carbon storage influence soil elevation, may alter vulnerability of coastal wetlands and the services they provide. Changes between functionally distinct woody mangroves and marsh vegetation are likely to alter ecosystem function, and changes in proportion of each vegetation type may have non-linear effects. Yet, we lack an adequate understanding of how changing foundation species identity and density will affect coastal ecosystem structure and function.
Mangrove range and cover fluctuate due to expansion during periods with warm winters and loss from severe freezes and anthropogenic impacts. In Texas, black mangrove (Avicennia germinans) cover increased by 74% between 1990 and 2010. With increasing winter temperatures, black mangroves are predicted to replace salt marshes throughout much of the Gulf Coast within this century. To understand likely functional implications of vegetation change, a common technique is to compare structural and functional differences among existing mangrove, salt marsh and mixed vegetation communities, but this method runs the risk of confounding the effects of the vegetation community with underlying abiotic conditions. Thus, we created a field experiment in which mangrove density was manipulated to represent 0-100% mangrove cover in ten 24 x 42 m plots in Port Aransas, Texas (just down the road from SWS 2016 Corpus Christi!). We tested how plant species identity and density alter: 1) microclimate 2) magnitude and mechanisms of changes in carbon storage 3) marsh vegetation regeneration and 4) habitat use by birds.
This talk will 1) outline changes in mangrove cover in coastal wetlands particularly in the US Gulf Coast, 2) utilize the literature of woody encroachment to expand understanding of functional implications of vegetation change in coastal wetlands, and 3) introduce our upcoming paper and additional findings highlighting the functional impacts of coastal wetland vegetation change.
Sean Charles is a PhD candidate at Florida International University (Major Professor Dr. John Kominoski). Sean is interested in how global and local anthropogenic impacts alter wetland ecosystem functions, services and vulnerability. Sean is currently investigating the ways that biogeochemical changes associated with sea-level rise and vegetation shifts caused by global climate change alter carbon storage and vulnerability in coastal wetlands, both in the Florida Everglades and in Coastal Texas. Sean is an active member of SWS, and is currently the student representative for the Education and Outreach and Wetland Ambassador committees.
Sean holds a master’s degree from the Virginia Institute of Marine Science (Major Professor Dr. Jim Perry), during which he looked at the development of functions in created forested wetlands and analyzed their success in the mitigation process.

April 2016: Climate Change and the Future of Blue Carbon
This webinar highlights what blue carbon is, why it's important and how it has an impact on climate change.
Salt marsh soils are the world’s most efficient carbon (C) sinks and have been so for millennia – but will they continue to be with warming climate and rapid rates of sea level rise? Over the last few thousand years the rate of sea level rise has enabled salt marsh vegetation to survive tidal flooding and accumulate C-rich soils, primarily through belowground production enhanced by contributions of mineral sediments deposited by tidal floodwaters. Globally, marsh soils store C, on average at a rate of 218 g m-2 yr-1, while emissions of the greenhouse gases methane and nitrous oxide are negligible. More importantly, marsh deposits hold at least 1,275 million metric tonnes of C globally. In recognition of their value as a C sink the carbon in salt marshes (along with that of mangroves and seagrasses) has been branded as “blue carbon”. There are now standards for calculation of the C stored through restoration of these ecosystems that can place blue carbon on the C market.
Funding from C markets should enhance restoration activities and restoration values should be based not only the renewal of active C sinks, but on stemming continued loss of the ancient C held in soils. However, since we can never “re-sequester” all the C that has been lost and we must not allow existing marsh to be replaced with “new” marsh through mitigation. If mitigation formulas included compensation for loss of existing marsh C stocks most mitigation projects would be untenable.

Dr. Chmura has used techniques of paleoecology, modern ecology and geomorphology to study tidal marsh response to sea level change, impacts of climate change and human perturbations on coastal ecosystems, and ecosystem services of natural and recovering salt marshes. Presently, her lab’s research is largely focused on impacts of nutrient pollution on coastal ecosystems, assessment of soil carbon stocks and rates, and greenhouse gases fluxes in salt marshes.
March 2016: Using Apex Predators & Trophic Cascades Mechanisms to Create Resilient Wetlands in a Warming World
Trophic cascades are relationships, in which, an apex predator produces direct efforts on its prey and indirect changes in faunal and floral communities. Direct predator effects on prey can be density-dependent (morality) and behavioral. By the early 1900s, apex predators had been removed from the ecosystems in North America, which lead to an irruption in prey population followed by unsustainable herbivory. Impacts in riparian areas and wetland include extensive removal of streambank vegetation, which resulted in elimination of habitat for taxa dependenct on vegetation, and signifcant reduction in biodiversity. These cascading effects further lead to streambank erosion, and increase in water temperature, and a decline in fish populations and diversity of wetland species. Environmental legislation and policy changes in the 1970s have led to restoration of apex predators to portions of North America.
These environmental changes led Cristina Eisenberg to present a comparison of North American riparian ecological community dynamics and resilency in systems with and without apex predatoring, which was drawn by a variety of studies. Then, she concluded her webinar presentation by dicussing how using apex predators and trophic cascades mechanisms to restore ecological resilency can effectively help mitigate climate change.

December 2015: Wetlands and Agriculture
This webinar links up with the conclusions and recommendations from the Conference, “Wetlands in Agricultural Landscapes”, held in České Budějovice from October 11-16, 2015. The Conference was actuated in order to evaluate the potential for integrating mostly temperate-zone wetlands into intensely managed agricultural landscapes. Over 170 participants from 20 countries attended, including both wetland and agriculture scientists, as well as nature conservationists and agriculture managers.
Wetlands are amongst the most threatened habitats on Earth; in some areas up to 80% of wetlands have been lost in Europe since 1700. The key driver in the loss and degradation of wetlands has been agriculture, although important indirect drivers have also been population growth and economic development. The pressure on wetlands, and consequent loss in their area and quality, has been most severe in countries with a long history of intense agriculture. This process may be further intensified by ongoing climate change. At the same time, however, many wetlands worldwide still remain important for fisheries as well as crop production, especially in small-scale farming. Moreover, many traditional farming practices take place in human-made wetlands such as wet meadows, rice paddies and fish ponds. The valuable functions and ecosystem services of wetlands were defined on the one hand, and the important role of agriculture in food production and landscape formation was on the other. The Conference devoted special attention to the following broadly conceived topics:
- Water retention and climatic effects of wetlands on surrounding agricultural land.
- Biodiversity conservation/promotion in relation to various agricultural management practices.
- Wetland restoration and creation in predominantly agricultural regions.
- Role of wetlands in the abatement of agricultural pollution from both point and non-point sources.
- Paludiculture, its advantages and limitations. Paludiculture is the agri- or silvicultural use of re-wetted peatlands and other wetlands.
- Legislation, financial incentives and involvement of stakeholders.
The general conclusions of the Conference have been summarized as follows: There is considerable scope for obtaining many mutual benefits from the use, restoration and creation of wetlands in intensely-managed agricultural landscapes. Wetlands help fulfil the current needs of agriculture by mitigating climate change, enhancing water retention, abating agricultural pollution, and also by offering potential for innovative agricultural technologies, also including the breeding of crops tolerant of water-logging or even shallow inundation. The dissipation of the energy of incoming solar radiation through intense wetland evapotranspiration results in a more balanced climate in agriculturally used areas adjacent to wetlands. In addition, wetlands support the diversity of species, habitats and landscapes, and provide opportunities for leisure time activities. The loss of these benefits through the destruction of wetlands can partly be compensated by wetland restoration. It is, however, expensive and may require decades to achieve the desired goals.

October 2015: Moving beyond Global Warming Potentials to Quantify the Climatic Role of Wetlands
Within the scientific, policy, and restoration communities, there is considerable interest in understanding the role of wetlands in influencing global climate. Wetlands are the single largest natural source of methane to the atmosphere but also sequester significant amounts of carbon in soils and woody biomass. In systems experiencing nitrogen pollution, wetlands can also emit substantial amounts of nitrous oxide to the atmosphere. Does the cooling effect due to carbon sequestration in wetlands offset the warming caused by the emissions of methane and nitrous oxide?
This webinar will cover 1) an overview of major concepts and biogeochemical processes related to the production and consumption of greenhouse gases by wetlands, 2) the historical approach of using global warming potentials (GWPs) to assess the climatic role of wetlands, and 3) alternate metrics (sustained-flux global warming and cooling potentials, SGWPs and SGCPs) and modeling approaches that can be used to determine whether wetlands have a net warming or cooling effect on Earth’s climate. Because one assumption underlying the use of global warming potentials is that greenhouse gases are emitted as a single pulse, we argue that the use of global warming potentials is inappropriate for use in wetlands (and, in fact, all ecosystems) since the production and consumption of greenhouse gases are not one-time events but occur year after year. The alternate metrics that we will discuss are more appropriate for use when gas fluxes persist over time and thus should provide a more accurate assessment of the climatic effect of wetlands. For cases where gas fluxes change over time (e.g., as a wetland matures following restoration) or if one is interested in knowing the lifetime climatic role of a wetland, a dynamic modeling approach is likely to provide more relevant information than would obtained with a fixed-timeframe metric such as the SGWP, SGCP, or GWP.
Many of the concepts that will be discussed in this webinar can be found in a paper that was recently authored by the presenter and Dr. J. Patrick Megonigal; individuals who wish to read the paper [Neubauer, SC and JP Megonigal. 2015. Moving beyond global warming potentials to quantify the climatic role of ecosystems.

September 2015: Innovative Policy Opportunities for Wetland Conservation
Coastal wetlands provide many benefits to human communities including increasing resilience to climate change and severe weather. Despite the important services they provide, coastal wetlands continue to be lost at rapid rates around the world, and the U.S. is no exception. At the same time, there are numerous opportunities to incorporate wetland restoration or protection into innovative or emerging environmental policies related to climate change mitigation and adaptation or sustainability. By better understanding and valuing the ecosystem services provided by coastal wetlands, we can leverage these policy opportunities to improve coastal management and decision making. This presentation will discuss three of those services and the policy opportunities associated with each: (1) coastal blue carbon where the carbon sequestration and storage of coastal wetlands can be incorporated into climate mitigation efforts; (2) natural (or green) and hybrid infrastructure for storm and erosion protection; and (3) nature and biodiversity impacts on human health.
Innovative Policy Opportunities for Wetland Conservation was presented by Dr. Ariana Sutton-Grier on September 15, 2015. Dr. Sutton-Grier is an ecosystem ecologist with expertise in wetland ecology and restoration, biodiversity, biogeochemistry, climate change and ecosystem services.
