- The study area is the Arid Lands Ecology (ALE) Reserve, a portion of the United States Energy Research and Development Administration's Hanford Reservation located in the semi-arid region of south-central Washington. Small experimental pastures were subjected to four consecutive years of moderate spring grazing by yearling steers. These pastures are unique in that they represent grazing stresses on previously ungrazed (by livestock) plant communities. These communities had been protected from grazing by livestock for more than 30 years under ERDA management. Bluebunch wheatgrass (Agropyron spicatum) was the major forage plant in the diet of the steers during the 1974 grazing season, followed by Cusick's bluegrass (Poa cusickii), Thurber's needlegrass (Stipa thurberiania), and hawksbeard (Crepis atrabarba). These four species made up approximately 93 percent of the total diet. The forage intake ranged from 9.9 kg/head/day to 10.9 kg/head/day during the grazing season. During this period, these steers gained a total of 21.6 kg/ha. This study presents the food chain relationships of Ca and P, and crude protein uptake from plants and conversion to animal tissues, which are available to man. (CH)
