Estimated annual shrub stem production based on premine stem <br />densities and mean herbaceous production. <br />° Estimated annual shrub productions/lbs/a <br />79.16 x gms/m2 Premine range sites A and B (1980-1985) <br />(79.16 gms/m2) (8.92, conversion factor) = 706.1 lbs/a <br />45% of the total annual production is shrubs based upon USDA SCS Brushy Loam <br />range site description. <br />(706.1 lbs/a) - (1-.45) = 1,283.8 total production, lbs. <br />(1,283.8 total prod., lbs) (.45 as shrub prod) = 577.7 lbs/a as shrubs. <br />Mean stem density, premine range sites <br />Assume range site A - 60% of the elk winter range survey area <br />Mean stem density = 34,560 stems/a <br />Assume range site B - 30% of the elk winter range survey area <br />Mean stem density = 36,098 stems/a <br />Assume range site C - 10% of the elk winter range survey area <br />Weighted mean stem density = 33,334 stems/a, premine. <br />(577.7 lbs/a shrub forage) (33,334 stems/a) _ .0173 lbs/stem <br />Estimated acres available within survey area and reclaim area as elk <br />winter range <br />Survey area elk winter range acres - 24,500 acres <br />(24,500 acres) - (1,425 approximate acres in cropland) = 23,075 available <br />acres <br />Approximately 5,100 acres will be disturbed by mining operations. <br />(5,100 acres) - (450 acres returned to cropland) = 4,650 acres available on <br />reclaimed lands <br />continued next page <br />
