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.

This report presents information on the coastal wetland resources and provides estimates of losses or gains tht occurred in the coastal watersheds between 1998 and 2004.

This report covers the mid-1970'2 to the mid-1980's, a period in which Federal, State, and local government programs and policies began to affect wetland use and conversion. For this reason, there has been intense interest by the scientific and governmental communities in these updated wetlands statistics. Although the data contained in this report generally predates more recent wetlands legislation, they provide information that can help to assess the effectiveness of public policies and programs that have been intended to reduce the loss of the Nation's remaining wetlands.
