The improvement of degraded sagebrush (Artemisia) rangelands in the Intermountain area was severely restricted during the first part of this century by lack of adapted plant material. Crested wheatgrass (Agropyron cristatum and A. desertorum) became available during the 1930's. Techniques and equipment for seeding were developed during the 1940's. The halogeton (Halogeton glomeratus) control programs gave great impetus to the seeding of crested wheatgrass on public lands during the 1950's. The established stands of crested wheatgrass provide an extremely valuable grazing resource in the Intermountain area.
Articles, citations, reports, websites, and multimedia resources focused on rangeland ecology, management, restoration, and other issues on American rangelands.
