Abstract

Astragalus barrii Barneby (Barr’s milkvetch) is ranked globally vulnerable (G3) by NatureServe and critically imperiled (S1) by the Nebraska Natural Heritage Program. A. barrii is designated a sensitive species by the USDA Forest Service (USFS) Region 2 (R2). The Oglala National Grassland (ONG), located in northwestern Nebraska in Dawes and Sioux County, is within the USFS R2 jurisdiction. The purpose of this survey was to: (1) search for and document all A. barrii present on designated areas of the ONG and (2) collect data on rare plant species and high quality native plant community occurrences.
