Elymus wawawaiensis Snake River wheatgrass

Formerly thought to be an ecotype of Pseudoroegneria spicata ssp. spicata. Cool season, very drought tolerant, long-lived perennial bunchgrass. Very similar to Bluebunch wheatgrass in appearance, growth characteristics, and adaptation, but more drought tolerant. Widely adapted to the sagebrush steppe of the Intermountain West. Very palatable to livestock and wildlife, especially in the spring. However, heavy spring grazing is detrimental to vigor and longevity.
