Riparian ecotones are an important natural resource with high biological diversity. These ecosystems contain specific vegetation and soil characteristics which support irreplaceable values and multiple ecosystem functions and are very responsive to changes in land management activities. Delineating and quantifying riparian areas is an essential step in riparian monitoring, planning, management, and policy decisions. USDA Forest Service supports the development and implementation of a national context framework with a multi-scale approach to define riparian areas utilizing free available national geospatial data. Riparian Buffer Delineation model (RBDM) v5.2 on ESRI ArcPro is used to process all the input data. RBDM recognizes the dynamic and transitional nature of riparian areas by accounting for hydrologic, geomorphic and vegetation data as inputs. Here we present and for the first time a national variable width riparian areas base map at a 10-meter spatial resolution for all NHDPlus 1:100K streams and the associated modeling technique.
