Summary Sheet
Title: Riparian Zone Analysis for Forest Land Cover for the Conterminous US
Abstract: One data layer describing the amount of forest land cover contained within a buffer
area extending 30 meters to each side of all streams contained within the basin (Watershed
Boundary Dataset (WBD) 12-digit Hydrologic Unit Code (HUC)) and from the edge of water
bodies such as lakes and ponds that are connected via flow to the streams. Streams and
waterbodies were taken from the National Hydrography Dataset (NHD) high resolution stream
network. Forest land cover is defined as 2006 National Land Cover Dataset (NLCD) land cover
codes 41, 42, 43, and 90. The data layer was created using the ATtlLA 2004 (Analytical Tools
Interface for Landscape Assessments) software extension within the Arc View 3.x desktop
Geographic Information System (GIS) package.
Keywords: ATtlLA; forest landcover; NLCD; riparian zone
Organization or location where data will be published: Online by NatureServe.
