The U.S. Army Corps of Engineers (COE) WetDataShed is software that allows you to simplify the wetland delineation process by automating calculations and providing a consistent means for collecting necessary data. There are various formats the user can select from for data entry that range from a simple delineation form, expanded and more detailed delineation form, to the ability to perform ecological or watershed scale studies using environment variables. The current version has the complete flora of North America matching the 1988 wetland plant indicator status list currently required for delineation purposes. In those few regions that have adopted 1993 revisions of the wetland plant indicator list, or would like to use the 1998 list, the software allows for changes to be made to those species that differ in status or synonymy.

This first publicly released version of WetDatShed (version 1.0) was released in January of 2004. It replaces previous beta development versions that were reviewed by Corps Districts and others nationwide. This software is being developed as part of a series of ongoing research and development efforts to support Regulatory functions within the COE.

WetDataShed software was developed at the Engineering and Development Center (ERDC), Cold Regions Research and Development Laboratory (ERDC/CRREL), Hanover, New Hampshire. The software was developed and designed by Robert Lichvar, Research Ecologist and the user interface and graphics were programmed with the assistance of Stuart Levasseur. The calculators and formulas used in the software were derived from the Corps of Engineers 1987 Wetland Delineation Manual and subsequent guidance from Corps Headquarters. The comprehensive plant species list used in this software, including both upland and wetlands plants, is based on the 1982 National List of Scientific Plant Names which later was the basis for development of the 1988 National List of Plants Species that Occur in Wetlands. These data bases were coordinated and shared with ERDC/CRREL by Porter B. Reed of the U.S. Fish and Wildlife Service (FWS). Calculations for contrasts of redoximorphic soil features were developed with collaboration with Steve Sprecher of the Corps of Engineers, Detroit District and Russell Pringle of the USDA, Natural Resources Conservation Service (NRCS).

Many Corps District staff and others made contributions to several earlier draft versions of this software. Earlier programming efforts or critical comments and suggestions were made by John Bruza , Michael Ericsson, Richard Gebhart, Richard Kelly, Daniel Martel, Steve Martin, Paul Minkin, Russell Pringle (NRCS), Porter B. Reed (FWS), Stuart Santos, R. Daniel Smith, Barry Sommerfeld, Steve Sprecher, Katherine Trott, Eric Warda, James Wakeley, Dale Yocum (FWS), and Sandy Zelan.

WetDataShed Software Distribution and Availability Statement

The WetDataShed executable code and documentation are public domain software that was developed by the Engineering Research and Development Center, Cold Regions Research and Engineering Laboratory (ERDC/CRREL) for the U.S. Army Corps of Engineers. The software was developed at the expense of the United States Federal Government, and therefore is in the public domain. This software can be downloaded for free from our internet site www.crrel.usace.army.mil/rsgisc.
ERDC/CRREL cannot provide technical support for this software to non-Corps users. However, we will respond to all documented instances of program errors. Documented errors are bugs in the software due to programming mistakes not errors due to user-entered data.

This software has been evaluated and inspected by the NRCS Software Test Lab in Ft. Collins, CO and is acceptable for installation on US Government computers.
