Range Plant * - Leaflet J I Columbia Needlegrass Reprinted August 1965 (Stlpa eolumbiana) Where does it grow? Colimbia needlegrass lives on open range in sagebrush and sunny hillsides in the timber. It often grows vhere other bunchgrassea have been killed out. It is usually found in dry soil on both hills and plains. It often comes in on high elevation ranges, along with squirrel tail and J\me grass, where the native grasses have been killed or where sagebrush has been burned. . There are several other common needlegrasses in Oregon; the best known are needle-andthread and Thurber's needlegrass. 1 V Is it important? It is a good livesSocIT'feed and stays green nearly all summer. This grass sometimes is one of the last good plants to go under excessive grazing and one of the first to return under improved management. It is a valuable forage plant.but not one of the very best. The seeds sometimes damage an animal by working into the ear or base of the tongue. What does it look like? This is a needlegrass with fine leaves and slender stems and it grows in tufts or bunches. The joints and heads are often purplish. The heads are fairly long and narrow with many twisted awns. Each awn grows on a grain and does not break loose without a reason. The grains have sharp points on the base, hence the name needlegrass. Description; Height — Up to 32 inches, usually about 20 to 2h. Heads — TFp to 8 inches long, but usually about 5 inches, purplish color, narrow, brush-like. The needlegrasses often come in when sagebrush has been burned. All of them have seeds with sharp-points (xl). COOPEJtATIVE EXTENSION SERVICE Leaves — Fine, narrow, flat when green, rolled when dry. OREGON STATE UNIVERSITY Cooperative Extension work in Agricuiture and Home Economics, F. E. Price, director. Oregon State University and the United States Department of Agricuiture cooperating. Printed and distributed in furtherance of Acts of Congress of May 8 and June 30, 1914. CORVAUIS Prepared by Elgin Comett, Wallowa County Extension Agent, Enterprise. Method of spread — Seeds with twisted, bent awns shatter on the ground but the awns twist when moistened and twist again when dry ^nd so work the seed into the soil. Other names -- Porcupine grass. Does it look like anything else? It resembles other needlegrasses but has finer leaves, stems, and beards than most. It resembles foxtail barley at times^ but foxtail has shorter heads that flare out more with straight awns, not bent and twisted.
