Wetlands are found in flat vegetated areas, in depressions on the landscape, and between water and dry land along the edges of streams, rivers, lakes, and coastlines.
Wetlands are important features in watershed management.
More than half of the original wetlands in the lower 48 states have been destroyed since 1600. 5. The origin of this philosophy came in 1987 at the National Wetlands Policy Forum which was sponsored by the U.S. Environmental Protection Agency. Fish and Wildlife Coordination Act - required U.S. Army Corps of Engineers to include ecological effects in their regulations. Prohibited U.S. Army Corps of Engineers from the use of 1989 Manual for Delineation of Wetlands, resulting in standardized use of the 1987 manual.
