Description: This data set represents the extent, status, and location of current NWI riparian mapping projects. Each project polygon contains information on the type and date of imagery used to map the riparian habitats and a link to a document about specific mapping techniques and habitat information for that project.
Description: This data set represents the extent, approximate location and type of riparian habitats in the western United States. These data delineate the areal extent of riparian habitats as defined by A System For Mapping Riparian Areas in the United States (USFWS 2009). Certain riparian habitats may be excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect riparian habitats. This dataset should be used in conjuction with the Riparian Mapping Areas layer, which identifies the extent and location of Riparian mapping projects.
