We evaluated sagebrush on 24 post-fire seeding sites encompassing >50,000 acres on the Snake River Plain in the Northern Great Basin, specifically in Southwest Idaho. Sites were initially identified using the Land Treatment Digital Library (LTDL; http://greatbasin.wr.usgs.gov/ltdl/; and Inciweb fire information (http://inciweb.nwcg.gov/) websites to identify seeding projects located in predominantly Wyoming big sagebrush sites (2,500 to 4,000 feet ASL; 2 sites also had A.t. vaseyana, 2 other sites had only A.t. vaseyana) that 1) had burned and were seeded within the year following fire, from 1987-2010, 2) but had not burned since, and 3) had information on seed sources. Standard USDA species abbreviations are used.
