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

Emergence of COVID-19 has emphasized that destruction of ecosystem leads to destruction of human. Ecosystem that protects us have been continuously altered by anthropogenic activities leading to climate change. This has recently resulted zoonotic diseases like corona viruses creating pandemic situation killing millions of people. Wetlands are diverse ecosystems in which slight alteration puts enormous impact on socio-ecological, physio-chemical and economical aspects. Among all, inland saline wetlands are unique in nature however least studied. Current study is conducted its impact on the largest saline wetland of India, Sambhar Salt Lake. Though it has been a Ramsar site since 23 March 1990 along with an Important Bird Area, it does not come under any protected area network of India. It used to be critical habitat of 289 migratory birds species coming from West Pacific Flyway, East-Asian Australasian Flyway, and the Central Asian Flyway that have now reduced to only 31 species as per our joint bird census report with Asian Water Census volunteers. To address these issues, this study analyzed soil salinity indices using satellite data of 1989, 1998, 2008, 2014, 2019 and 2020 integrating climatic parameters and ground data picturize impact of past climatic trends and lockdown due to COVID-19 24 (March 2020 to 30 May 2020) on the lake. Results state that salinity has decreased drastically over the years until 2019 however, the lake is reviving during pandemic situation. Lake is full of water; soil salinity value has increased indicating its unique halophiles and halophytes reviving into the lake. Once again, lake is ready to welcome its rich biodiversity if there is least human interference.

November 2020: Resurrecting ‘ghost ponds’ and other approaches in pond restoration and conservation

November 19, 2020 | 1:00 p.m. ET

Resurrecting ‘ghost ponds’ and other approaches in pond restoration and conservation

GP150 resurrectedGrowing recognition of the importance of ponds for landscape-scale biodiversity has led to considerable interest in their conservation, focusing on new pond creation, or existing pond restoration. However, there is a third approach; the re-excavation of ‘ghost ponds’ – former ponds deliberately filled in for agricultural intensification. This presentation will explore how “resurrecting” ghost ponds and restoring overgrown ponds can provide important benefits for farmland biodiversity, with historic pond sediments acting as time capsules for the seeds of native wetland plants. Given the global abundance of wetlands and ponds which have been filled-in during agricultural land intensification, the resurrection and restoration of these habitats from their historic seedbanks provides a valuable tool for conservation practitioners and policy makers aiming to improve biodiversity within farmed landscapes.


Presenter: Emily Alderton

headshotEmily Alderton has a Master’s and PhD in Aquatic Science from University College London (UCL). Emily received her PhD from the Environmental Change Research Centre (ECRC) at UCL in 2017, for her thesis on “Ghost ponds”: Resurrecting lost ponds and species to assist aquatic biodiversity conservation. Emily’s research focused on mapping historic pond loss across the county of Norfolk (U.K), understanding the impacts of pond loss and pond degradation on aquatic biodiversity, and investigating the potential role that resurrecting in-filled “ghost ponds” could play in helping to restore biodiversity in fragmented pond landscapes. During her PhD, Emily was involved with the Norfolk Ponds Project, an award-winning multi-partner project working to conserve and restore Norfolk’s ponds. Emily contributed to pond restorations, educational open-farm events, and training days for farmers and landowners on how best to restore and manage ponds in farmland.

Since 2018 Emily has been working in Massachusetts (U.S) as an Ecological Scientist at BSC Group Inc., where she provides field services including wetland delineations, habitat surveys and invasive species surveys, and federal, state, and local level permitting services.
