Interpretive Summary: 'Recovery' western wheatgrass (Pascopyrum smithii [Rydb.] A. Love) was released in December 2009, by the USDA-ARS, the U.S. Army Corps of Engineers-Engineer Research and Development Center, and the USDA-NRCS. Recovery was developed for reseeding rangelands following severe disturbance, frequent fires, and soil erosion with selection emphasis on improved and faster seedling establishment. During the establishment year, Recovery had increased frequency of seedlings when averaged across eight locations than 'Arriba', 'Barton', 'Flintlock', 'Rodan', and 'Rosana' western wheatgrasses. Recovery continued to have superior stand until 4 to 6 years after planting, when due to their rhizomatous nature, all the western wheatgrasses had similar stand frequencies. Foundation seed of Recovery is available through the Utah Crop Improvement Association and the University of Idaho Foundation Seed Program.
