Interpretive Summary: A greater variety of native plant materials is needed to service restoration activities in the rangelands of the Intermountain West. We evaluated 32 collections of a newly recognized subspecies of bottlebrush squirreltail collected in Oregon, Idaho, Nevada, and California for traits relating to maturity, canopy, biomass, and seed production. Antelope Creek and Pleasant Valley, both from the Blue Mountains of Oregon, displayed desirable seed yield and have been released for general use. These two plant materials are the first releases of this new subspecies.

Technical Abstract: Two new natural-track pre-variety germplasms (selected class), Antelope Creek and Pleasant Valley, were released by the USDA-Agricultural Service and the Utah Agricultural Experiment Station in 2009 and 2010, respectively. Antelope Creek Germplasm is recommended for use in the western Blue Mountains of Oregon and the eastern Cascade slopes and foothills of Oregon and northeastern California. Pleasant Valley Germplasm is recommended for use in the eastern Blue Mountains of Oregon, Washington, and Idaho. Both germplasms are members of the unofficially designated bottlebrush squirreltail subspecies "C," which possesses a distribution that is centered in central and eastern Oregon.
