Snake River wheatgrass

Elymus wawawaiensis

Cool season, long-lived, perennial bunchgrass formerly thought to be a regional type of Bluebunch wheatgrass (Pseudoroegneria spicata ssp. spicata). Similar to Bluebunch wheatgrass in appearance, growth characteristics and adaptation, but more drought tolerant, resulting in it often being used in place of Bluebunch throughout the western U.S., though its natural distribution is limited to Idaho, Washington and Oregon. Palatable to livestock and wildlife, especially in the spring. Heavy spring grazing is detrimental to vigor and longevity
