Status and Trends of Wetlands in the Conterminous United States 2009 to 2019

Under the Emergency Wetlands Resources Act of 1986, we are required to submit decadal reports to Congress on wetland status and trends (area and change). These National Wetlands Inventory (NWI) Program reports provide the data necessary to effectively manage wetlands and determine if the goal of “No Net Loss” of wetlands is achieved. This is the 6th report in a series spanning nearly 70 years. Covering the period between 2009 to 2019, the report provides the extent of wetlands in 2019, as well as changes in wetland area and type between 2009 and 2019 for the contiguous United States. It highlights the importance of wetlands in providing ecosystem services, as well as the effects of wetland loss, gain, and type change. The report includes a recommendation and four strategies aimed at achieving no net loss of wetlands, including vegetated wetlands.
