Opis

The National Wetlands Inventory Program (NWI) has been producing wetland maps and geospatial wetland data for the United States since the mid-1970s. The focus on the program has been on two fronts: 1) map or digital database preparation and delivery to the public, and 2) projecting and reporting on national wetland trends using a probability-based sampling design. The status of mapping has been made available through various media throughout the program's 30-year history (e.g., state atlases, regional status maps, and now through the internet via the Wetlands Mapper online tool). Annual progress reports have been produced for internal uses, but the NWI has never produced a national status report for public distribution. Given the evolution of the NWI, the diversity of products and activities with which the program is involved, and the wide public use of our products, the NWI decided to prepare this first status report. Being the first such report, it provides an introduction to the NWI Program in addition to reporting on the annual progress and activities across the regions. Future annual reports will focus on yearly accomplishments.
