Wetlands provide unique ecological functions and critical habitat for a variety of sensitive or geographically restricted species. West Fork Environmental applies its diverse biological research and monitoring experience to services that can be adapted to any project or site-specific wetland issue. Staff are formally trained in conducting jurisdictional wetland determinations and delineations using the US Army Corps of Engineers Wetland Delineation Manual and Interim Regional Supplements and are also certified in using Washington State Department of Ecology's Washington State Wetland Rating System.
