Grass Mixtures for Seeding Sagebrush Lands

Abstract

Four wheatgrasses were seeded alone and in mixtures in 1945 near Dubois, Idaho. By 1955, fairway wheatgrass had spread by seed to all plots and has remained the most abundant species. Intermediate and pubescent wheatgrasses spread slower, mainly by rhizomes, and by 1967, they were present on all treatments. At the end of 25 years these three species are growing well together. Bluebunch wheatgrass has practically disappeared from the study area.
