Geospatial data for Great Basin perennial montane watersheds - geomorphology, hydrology, vegetation, disturbance and species

Multiple partners working together developed a multiscale approach for assessing the geomorphic sensitivity of streams and ecological resilience of riparian ecosystems, including meadows, in upland watersheds of the Great Basin to disturbances and management actions. This data publication contains the geospatial data, representative of 2020, resulting from that work. The study area, the Great Basin of North America, includes portions of Nevada, Utah, California, Oregon, and Idaho. Nine shapefiles are included, which provide the seven regions (1) and the mountain ranges (2) identified in the study area, streams within each watershed (3) along with the stream heads (4), longest stream (5), lowest drainage points (6), and the stream head that has the farthest stream distance from the pour point (7), and the valley bottom which is considered the area surrounding the stream that is less than 15 meters above the stream's elevation (8) for each watershed. Also included are the watershed boundaries (9) and additional watershed information related to climate, topography, and wildlife. Also included is an ArcGIS map associated with these shapefiles.
The approach builds on long-term work by the research and management partners on the geomorphic sensitivity and ecological resilience of these systems to stressors and disturbances. At the core of the assessments is information on past and present watershed and stream channel characteristics, geomorphic and hydrologic processes, and riparian and meadow vegetation characteristics.
