Can anyone help figure out the number of jobs that are directly or indirectly related to wetland work and regulation, and that would be lost if the current administration manages to *curb*, *scale back*, or by any other euphemism cripple federal wetland regulation? I know many agency people would lose their jobs, consultants like me would lose our jobs, etc., but is there an estimate of how many existing, REAL jobs across the nation would be lost if developers and their cronies get their way and kill off these "onerous" regulations that are somehow costing jobs and keeping the economy stagnant through indefinable means?<br />
<br />
I'm not an investigative reporter or any other kind of journalist. This is something I've been thinking about for the last few months but I have no idea where or how to get the information I need. I want actual facts to counter *alternative* ones. Thanks in advance for any assistance you can provide.<br />

auto data forms? http://sws.org/Forum/question/auto-data-forms.html http://sws.org/Forum/question/auto-data-forms.html I'm wondering if anyone has made an app or mail merge doc or something to simplify filling out wetland data forms. Ideally one that would have macros, where you input the 4 letter species code and it populates the form with the genus, species, and indicator status. I've seen something similar that the ACOE has for the midwest, but nothing for the PNW.

Piezometer Stability in Long Term Vertisol Hydrology Studies in the Texas Gulf Coast Prairie<br />
Wesley L. Miller<br />
USDA-NRCS Soil Scientist (retired)<br />
Victoria, Texas<br />
May 15, 2016<br />
<br />
The high shrink-swell characteristics of Vertisols as they go through seasonal wet-dry cycles, associated deep open cracks during dry periods, and bypass flow along cracks and/or slickensides (Griffin et al., 1992) (Sprecher, 2008) make the measurement and interpretation of Vertisol hydrology field studies challenging. One question in recent years concerns the physical stability of piezometers made of schedule 40 PVC pipe during long term Vertisol hydrology field studies (Jacob et al. 1997). In the past several years piezometers made of schedule 40 PVC pipe were removed from two long term Vertisol hydrology studies in the Texas Gulf Coast Prairie that allowed an evaluation of this possible stability problem.<br />
<br />
Between 1989 and 2004 there were two formal USDA Natural Resources Conservation Service and university cooperative sponsored long term soil hydrology studies that included Vertisols in the Texas Gulf Coast Prairie. Piezometers were made of schedule 40 PVC pipe. At each monitoring site (eight total) there were three piezometers at 25 (or 30 cm), 50, 100 and 200 cm depths (total of twelve). Additional piezometers that ranged from 400 to 625 cm deep were placed at selected monitoring sites.<br />
<br />
The first long term Vertisol hydrology study in most Texas Gulf Coast Prairie was part of the USDA International Committee on Aquic Soils Study from 1989 to about 1996 (Kimble, 1992). One of the Vertisol study sites was located in Victoria County, Texas, on Laewest clay, fine, smectitic, hyperthermic Typic Hapluderts (Soil Survey Staff, 1999) in an area of native prairie. <br />
<br />
The possibility of piezometer failure due to tilting during long term Vertisol hydrology studies was first mentioned by Jacob (Jacob et al., 1997) based on a field observation made at the Victoria County, Texas, Laewest clay site in 1996 in preparation of a chapter on Vertisol wet soil studies. The piezometers had been in the ground seven years at the time the field observations were made. All piezometers (1.9 cm ID schedule 40 PVC pipe) were functional in 1996. Only one 100 cm deep well made of 25 cm diameter PVC pipe (50 cm above ground) on a microhigh had tilted the most from vertical about 5 to 10 cm (W.L. Miller, unpublished data).<br />
<br />
In 2005 the piezometers were removed from the Laewest clay site. Piezometers had been in the ground for about sixteen years. The depth of several of the piezometers was checked at each microhigh-microlow location, and the 500 cm piezometer was also checked. We could measure to the designated piezometer depth and all were functional (allowed water flow). Remaining geofabric covering the open end and eight narrow slots at the bottom of the piezometers was in good condition.<br />
<br />
The second long term Vertisol hydrology study in the Texas Gulf Coast Prairie from 1996 to 2004 was the Soil Characterization and Hydrological Monitoring Project, Brazoria County, Texas, Bottomland Hardwood Vertisols (Miller and Bragg, 2007) (Bottomland Hardwood Vertisol Study). Soils were Pledger clay (nonponded), very-fine, smectitic, hyperthermic Typic Hapluderts (Soil Survey Staff, 1999) and Churnabog clay (ponded) very-fine, smectitic, hyperthermic Typic Epiaquerts (Soil Survey Staff, 1999). There were three nonponded and four ponded bottomland hardwood monitoring sites. Standard depth piezometers at each monitoring site were made of 4.5 cm ID schedule 40 PVC pipe. At five selected sites an additional piezometer made of 1.9 cm ID schedule 40 PVC pipe was installed. These piezometers ranged from 400 to 625 cm deep into contrasting sandy and loamy layers below the clays.<br />
<br />
In 2004 a study was conducted to measure the vertical (heave) and horizontal (throw) movement of the soil and/or piezometers at the Bottomland Hardwood Vertisol Study sites (Bragg and Miller, 2006). The piezometers had been in the ground about eight years. Soil movement above original ground level marked on piezometers when installed ranged from 0 to 9 cm. Tilt of piezometers from vertical ranged from 2 to 5 cm (Miller and Bragg, 2007). All of the piezometers we checked were still functional.<br />
<br />
In December, 2010, the piezometers and equipment were removed from the Bottomland Hardwood Vertisol Study sites. The piezometers had been in the ground for about fourteen years. Based on observed piezometer PVC pipe field conditions, none had tilted significantly from the observations made in 2004, or had failed (were not collapsed at depth), including the 400 to 625 cm deep piezometers. When the piezometers were removed, remaining geofabric covering the open end and eight narrow slots at the bottom of the piezometers was in very good condition. Piezometer slots were not blocked and still allowed water flow.<br />
<br />
The results of these two long term Vertisol hydrology studies in the Texas Gulf Coast Prairie indicated that piezometers made with schedule 40 PVC pipe did not tilt significantly or fail (collapse) due to shrink-swell cycles during monitoring periods of fourteen to sixteen years. Quality geofabric covering the slots and open bottom end of the piezometers did not deteriorate significantly during the same time periods.<br />
<br />
Bypass flow along Vertisol open cracks and/or slickensides to the deeper piezometers was observed several times. Most notable bypass flow usually occurred within a relatively short period after large, short duration precipitation events during dry periods when cracks were open and extensive at the surface (W. L. Miller, unpublished data). We also observed that over time, at ponded sites in both studies, a few deeper piezometers leaked water along the sides due to incomplete bentonite sealing.<br />
<br />
Leakage along piezometer sides can be avoided by first digging very straight holes to the required depth. Then, after the piezometer is inserted into the hole and as the bentonite seal is added, tamping the bentonite completely around the piezometer PVC pipe. In later wet soil studies we used a same ID PVC pipe as the piezometer pipe, cut in half lengthwise and slightly longer than the piezometer being installed, to accomplish the tamping of the bentonite completely around the piezometer.<br />

Forest Biofuels letter http://sws.org/Forum/question/forest-biofuels-letter.html http://sws.org/Forum/question/forest-biofuels-letter.html While I think it's great that SWS engaged with other scientists and societies on critical issues such as biomass, I'm not sure I was so please by adding our name to a letter related opposing the use of forest biofuels for energy. This letter ignores a lot of the variables still in play for this issue and supporting a complete opposition to forest biomass is not prudent at this stage.<br />
<br />
There is an awful lot of misinformation out there regarding carbon and biomass, and Dr. Booth has framed it as a binary discussion where in reality there is a great deal of nuance related to this matter. <br />
<br />
I worked in rural development/watershed &amp; forestry issues in the northern Sierra/southern Cascade region for four years and disagree with blanket opposition to forest biomass policies. In that part of the world, wetlands are 'meadows' and there may be benefits to wetland areas from forest thinning. Or not. It's still being studied and it's a fascinating area - to me the jury is still out.<br />
<br />
I'm glad to see SWS engage on an issue with so many moving parts and policy implications, but I'd rather see SWS as a facilitating medium for such a complex issue rather than signing on.<br />

The book title is: The Many Faces of a Most Common Tree: Extraordinary Diversity in Native Red Maple. <br />
<br />
The book description is as follows:<br />
<br />
This work photographically documents the impressive breadth of variability in the bark of native red maple (Acer rubrum), recognizing similarities and differences and categorizing the different bark patterns. An overview of general patterning is provided, and the presentation of bark types begins with those that are common and with those that are smooth to provide starting points from which to build upon with the many variations. Patterns that are considered peculiar or even unique are recognized, and visual similarities to other tree species are informally noted. Other trunk characteristics are presented, and a section on caricature-like trunks adds a light-hearted touch. The book begins with images of brilliant spring flowers and closes with images of vibrant autumn foliage to further highlight the beauty of the tree.<br />
<br />
An image of the book cover is attached, and an Amazon link has been provided. <br />
<br />
For those who have an interest, I hope you enjoy it! <br />
<br />

<br />
Generically, I'm looking for anything on how water moves (or doesn't move) in/over shallow bedrock systems. Specifically, I'm looking for information on indirect effects of mining on wetlands in fractured bedrock (basically lateral effects). <br />
<br />
Anything would be helpful. So far I'm finding mostly anecdotal information.<br />

Nominees/volunteer needed for SWS representative to EPA Wetland Advisory committee http://sws.org/Forum/question/nominees-volunteer-needed-for-sws-representative-to-epa-wetland-advisory-committee.html http://sws.org/Forum/question/nominees-volunteer-needed-for-sws-representative-to-epa-wetland-advisory-committee.html <br />
EPA has asked SWS to nominate someone to serve on a Federal Advisory Subcommittee under the National Advisory Council for Environmental Policy and Technology (NACEPT) for an effort related to Clean Water Act (CWA) Section 404(g), which are the regulations pertaining to state and tribal assumption of the CWA Section 404 program. <br />
<br />
EPA wrote: “CWA Section 404(g) allows for states and tribes to assume administration of the dredge and fill permitting and enforcement program for certain waters. The subcommittee has a narrow charge on waters which a state or tribe may assume permitting responsibility for under an approved CWA Section 404 program. The subcommittee will seek to provide clarity on determining the waters for which the state/tribe has CWA Section 404 permit responsibilities, and for which the USACE retains CWA Section 404 permit responsibility. This subcommittee will be known as the “Assumable Waters” subcommittee under NACEPT.<br />
<br />
This notice solicits nominations to fill up to 25 vacancies to serve through spring of 2016. EPA is committed to diversity. To obtain a fair and balanced membership, representation is sought from the following stakeholder groups:<br />
• Academia <br />
• Industry/Business groups<br />
• NGO/Environmental groups <br />
• National Associations<br />
• State Associations <br />
• State governments <br />
• Local or Regional governments <br />
• Tribal governments and Indigenous organizations <br />
<br />
We also anticipate Federal representation from the US Army Corps of Engineers, the US Fish and Wildlife Service and the EPA. <br />
<br />
Within these stakeholder groups, the EPA is seeking nominees with knowledge of the CWA Section 404 program, federalism, state and tribal wetland permit programs, policy and legal backgrounds in the CWA, and those with working knowledge of effective state federal partnerships. Nominees will be considered according to the mandates of the Federal Advisory Committee Act (FACA), which requires committees to maintain diversity across a broad range of constituencies, sectors, and groups. Background and experiences that would help members contribute to the diversity of perspectives critical to this issue include: geographic, economic, social, cultural, educational backgrounds, and professional affiliations. All nominations will be fully considered. Please share this opportunity as you see fit.“<br />
<br />
Please let me know if you would like to nominate one of our SWS members (or would like to volunteer) for this very important position. The EB will review all entries and select a nominee. Please note that time is of the essence and we do need to move fairly fast on this.<br />
<br />
