Abstract:

This study measured trends in wetland acreage in the conterminous United States between 1998 and 2004. The Cowardin et al. (1979) wetland definition was used to describe wetland types. Wetland trends were measured through the acquisition and analysis of contemporary remotely sensed imagery for 4,682 randomly selected sample plots throughout the conterminous United States. Field verification was completed for 32 percent of the sample areas in portions of 35 states. This provided a scientifically grounded analysis of the aerial extent of all wetlands in the lower 48 states, regardless of ownership.
