In the growing season following a severe one-year drought in central and eastern Oregon (precipitation 49% of average), various parameters of individual ungrazed and grazed plants of bluebunch wheatgrass, Idaho fescue, Thurber needlegrass, and crested wheatgrass at 11 locations were evaluated. An average of 43% above-average precipitation occurred during the study growing season. Lightly grazed Idaho fescue and bluebunch wheatgrass produced as much, and in some cases, more height growth, final weight, and seed stalks than ungrazed plants. No differences occurred between moderately grazed and ungrazed bluebunch wheatgrass and Idaho fescue. Moderately grazed crested wheatgrass produced similarly to ungrazed plants but started growth more slowly. Grazing heavier than 70% reduced production and height of Idaho fescue and Thurber needlegrass but did not significantly impact bluebunch wheatgrass. No plant mortality occurred regardless of past grazing use.
