<br /> producing 9.8 grams. Perennial forbs produced 61.9 grams with nettleleaf <br /> horsemint, silvery lupine, one-flowered helianthella, leguminous forbs and <br /> other miscellaneous forbs comprising the majority of the forbs. <br /> Mean annual herbaceous production from reference area samples was <br /> 183.4 grams per square meter. Perennial grasses produced 81.6 grams per <br /> square meter of which Kentucky bluegrass produced 53.7 grams per square meter <br /> and nodding brome produced 17.5 grams per square meter. Perennial forbs <br /> produced 79.5 grams per square meter, flowered helianthella produced 19.5 <br /> grams per square meter and silvery lupine produced 16.8 grams per square <br /> meter. Other miscellaneous perennial forbs produced 32.3 grams per square <br /> meter. Annual forbs produced 21.6 grams per square meter. Total above <br /> ground herbaceous production in the reference area was significantly greater <br /> than that of herbaceous production in study area samples. <br /> Density - Total shrub density within the mountain shrub vegetation type <br /> was 53.9 individual shrubs per 50 square meters.

Converting oven to <br /> air dry forage by a factor of 1.11, yields 1500 ibs/acre available herbaceous <br /> air dry forage. Assuming a 50 per cent utilization factor and 90D lbs/acre <br /> cattle animal unit,the cattle carrying capacity was 0.83 AU M's per acre. For <br /> sheep the carrying capacity was 5.00 AU M's per acre. <br />16 <br />• _........ ...._.... ..-,•••••••.•• - •• );zhitiit7b,Tfeiri'S"~~~~~~~ ~- ~~~~ ~~~kevisioriDafe:-03/06/07 <br />21 Revision No.: PR-02 <br />
