Duration of Seeded Stands on Terraced Mountain Lands, Davis County, Utah

Abstract

Thirty-seven species were seeded experimentally in northern Utah on 14 areas on depleted and terraced mountainous rangelands from 1936 to 1939. Seventeen species had fair to excellent 3-year-old stands. Most stands decreased; and in 1971 only smooth brome, tall oatgrass, intermediate wheatgrass, and red fescue have fair to excellent stands. Smooth brome spread slowly by rhizomes and usually formed a dense sod. Tall oatgrass spread by seed with a poor to good stand on ten times the original seeded area. Intermediate wheatgrass has spread by rhizomes and forms a good stand on the large plot where it was seeded in 1941. Red fescue did well on favorable sites but was not tested under typical conditions. Native grasses, forbs, shrubs, and trees have reinvaded the seeded areas.
