NWI+ Reports


Online reports are available for most, if not all, project areas where NWI+ data have been produced.  Reports are arranged by states alphabetically. (Note: Digital geospatial data may not be available for some of the older studies since this work has been ongoing since the late 1990s.)

What is NWI+?

NWI+ was a regional initiative by the Northeast Region of the U.S.  NWI+
Fish and Wildlife Service's NWI Program.  It was supported by the NWI through regional mapping projects funded by the U.S. Fish and Wildlife Service and federal and state cooperators from the mid-1990s to 2015.  It began as a regional demonstration initiative in how NWI data could be enhanced with hydrogeomorphic attributes for landscape position, landform, water flow path, and waterbody type (LLWW descriptors) to increase the functionality of NWI data for better characterizing wetlands, for predicting wetland functions at the landscape or watershed level, and for assessing the impact of wetland changes on wetland functions.  The expanded database and its outputs were called NWI+ data as the results go beyond the standard NWI mapping.  Production of NWI+ data was a special project of the NWI with work mostly in the Northeast Region but also undertaken by some states (e.g., Colorado, Georgia, Montana, and New Mexico) in other Regions when they were updating NWI data.  While the demonstration was successful and NWI+ or similar data continue to be generated by several states, the national NWI Program (the U.S. Fish and Wildlife Service) is no longer able to support NWI+ initiatives.  Moreover budget cuts for the program have made the NWI+ NWI more dependent than ever on having cooperators update even the basic NWI database.
