Data from status and trends provide important long-term trend information about specific changes and places and the overall status of wetlands in the United States. The historical data base that the Service has developed through Status and Trends, provides photographic evidence of land use and wetlands extent dating back to the 1950s. This provides an accurate record to assist in future restoration efforts.--Publisher description.

This study measured wetland trends in the conterminous United States between 1998 and 2004. The estimates of estuarine emergent area were made prior to Hurricanes Katrina and Rita during the summer of 2005. The Cowardin et al. (1979) wetland definition was used to describe wetland types. By design, intertidal wetlands of the Pacific coast, reefs and submerged aquatic vegetation were excluded from this study.
