It can be seen from the values obtained during premining sampling that sagebrush- grass types exceeded the favorable years projections in dry matter yield in 1979 as set forth by [he Soil Conservation Service. The mountain shrub data indicate an unfavorable year. However, only herbaceous production was sampled for in the mountain shrub community during 1979. As previously mentioned, the range site descriptions and dry matter yields, as described by the Soil Conservation Service, are based on broad soil characteris- tics. Premining sampling at Trapper Mine will continue over the next 3 to 5 years to determine site specific growth patterns within the proposed permit area. 2-178
