Abstract | Objectives of this investigation were two-fold: (l) to determine crested wheatgrass production on selected range sites and (2) to evaluate present and potential production on public and private lands in the study area. Field studies were carried out in 1953 and 1964 near Jordan Valley, Malheur County, Oregon, on the East Cow Creek and Soldier Creek Allotments of the Bureau of Land Management, Vale Grazing District. Sixteen paired exclosures with nine, 9.6-square-foot circular plots within each exclosure were used to determine production on range sites in improved and unimproved condition. The improved areas had been seeded to crested wheatgrass. Three different range sites were differentiated on the basis of dominant shrub, dominant grass, soils, landforms, and aspect. Crested wheatgrass two-year average production varied from 250 to 1,350; 250 to 1,850; and 150 to 1,500 pounds per acre on Sites I, II, and III, respectively. A range inventory method was developed and the entire East Cow Creek Allotrnent (50, 175 acres) and permittee properties (14,010 acres) were inventoried. Present production, potential production, and information for determining acreages in need of and suitable for various range improvement and management practices were obtained. |
