The National Wetlands Inventory (NWI) was established by the United States Fish and Wildlife Service (FWS) to conduct a nationwide inventory of U.S. wetlands to provide biologists and others with information on the distribution and type of wetlands to aid in conservation efforts. To do this, the NWI developed a wetland classification system ...
The Service's wetlands data forms a layer of the National Spatial Data Infrastructure (NSDI) and is an important component of Department's geospatial line of business portfolio and actively supports the E-government initiative through the Geospatial One- Stop and The National Map. [9]
The mission of the National Wetlands Research Center is to develop and disseminate scientific information needed for understanding the ecology and values of U.S. wetlands and for managing and restoring wetland habitats and associated plant and animal communities. Its mission's primary goal is to bridge the gap between researchers and decision ...
The wetland status of 7,000 plants is determined upon information contained in a list compiled in the National Wetland Inventory undertaken by the U.S. Fish and Wildlife Service and developed in cooperation with a federal inter-agency review panel (Reed, 1988). The National List was compiled in 1988 with subsequent revisions in 1996 and 1998.

This list of Ramsar sites in the United States are those wetlands that are considered to be of international importance, protected under the Ramsar Convention treaty. The United States as of 2020, has 41 sites designated as "Wetlands of International Importance" with a surface area of 1,884,551 hectares (7,276.29 sq mi; 18,845.51 km 2).
The North American Wetlands Conservation Act signed into law by President George H. W. Bush on December 13, 1989 authorizes a wetlands habitat program, administered by the United States Fish and Wildlife Service, which provides grants to protect and manage wetland habitats for migratory birds and other wetland wildlife in the United States, Mexico, and Canada.
The countries with most sites are the United Kingdom with 175 and Mexico with 142. The country with the largest surface area of listed wetland is Bolivia, with around 148,000 square kilometres (57,000 sq mi). [4] The Ramsar Sites Information Service (RSIS) is a searchable database which provides information on each Ramsar site. [5]
