i~ <br />Big sagebrush was the dominant shrub with 24.6 individuals per 50 square <br />meters. Western snowberry and Douglas rabbitbrush had 12.4 and 10.2 <br />individuals per 50 square meters, respectively. Other important shrubs <br />included rubber rabbitbrush and fourwing saltbush in the sagebrush bluebunch <br />wheatgrass phase, and Woods rose, Gambel oakbrush and western snowberry in <br />other phases. <br />Species diversity - The mean number of species encountered along the 50 <br /> <br />meter point cover transect was 9.6 and 11.3, respectively, for study and <br />reference area samples (Table 3.7 ). <br />Livestock Carrying Capacity - Average herbaceous production in the <br />sagebrush grassland type was 1100 lbs/acre oven dry forage. Converting oven <br />to air dry forage by a factor of 1.11, yields 1222 lbs/acre available <br />herbaceous air dry forage. Assuming a 50 per cent utilization factor and 900 <br />lbs/acre cattle animal unit,the cattle carrying capacity was 0.68 AUM's per <br />acre. For sheep the carrying capacity was 4.07 AU M's per acre. <br />3.3.4 Meadow <br />The meadow vegetation type occurred along the creeks and most major <br />drainages throughout the study area. Major areas occur along Good Spring, <br />Wi 1 son, West Fork of Good Spring and East Fork of Wi 1 son creeks. The meadow <br />type was exceedingly variable dependent upon moisture and soils. In areas <br />where water was at the surface sedges and rushes dominated. Nebraska sedge, <br />common cattail and bulrush were common (figure 3.11). Willows dominated <br />several areas although they never formed continuous thickets. Grasses, <br />including Kentucky bluegrass, Great Basin wi7drye, western wheatgrass, <br />slender wheatgrass, dominated most areas (figure 3.12). Numerous forb species <br />also occured within this type. <br />The meadow type is very productive and is easily grazed because of its <br />20 <br />Exhibit 10, Item 5 <br />25 <br />Revision Date: 03/06/07 <br />Revision No.: PR-02 <br />
