<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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 conjunction with the Riparian Mapping Areas layer, which identifies the extent and location of Riparian mapping projects.</SPAN></P></DIV></DIV></DIV>
The present goal of the Service is to provide the citizens of the United States and its Trust Territories with current geospatially referenced information on the status, extent, characteristics and functions of wetlands, riparian, deepwater and related aquatic habitats in priority areas to promote the understanding and conservation of these resources.

Publication Data

The riparian maps were produced as topical overlays using U.S. Geological Survey topographic maps as the base. The hard copy product is a composite map showing topographic and planimetric features from the USGS map base and riparian habitats from the Service's topical overlay. Thus, the data are intended for use in publications, at a scale of 1:24,000 or smaller. Due to the scale, the primary intended use is for regional and watershed data display and analysis, rather than specific project data analysis. The map products were neither designed or intended to represent legal or regulatory products. Questions or comments regarding the interpretation or classification of riparian habitats can be addressed by visiting: https://www.fws.gov/page/national-wetlands-inventory-frequently-asked-questions. These data were developed in conjunction with the publication; A System For Mapping Riparian Areas in the United States (USFWS 2009). These spatial data are not designed to stand alone. They form topical overlays to the U.S. Geological Survey 1:24,000 or 1:25,000 scale topographic quadrangles. These data will also work with current available digital wetlands data. Note that riparian delineations were drawn to follow the extent of riparian features described by this project and may not match surface features shown on other base maps. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Arc/INFO format, this metadata file may include some Arc/INFO-specific terminology.

This data set represents the extent of riparian habitats that can be determined with the use of remotely sensed data and within the timeframe for which the maps were produced. Riparian habitats are only shown in the western United States, Where mean annual evaporation exceeds precipitation by more than 10 inches. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data, and the amount of ground truth verification work conducted. There is a margin error inherent in the use of imagery, thus detailed on-the-ground inspection of any particular site, may result in revision of the wetland boundaries or classification, established through image analysis. Riparian habitats or other mapped features may have changed since the date or the imagery and/or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site.
