~. <br />• <br />~`~ <br />The herbaceous production summary for mountain shrub in the pre- <br />mine area is shown in Table 3. <br />Mountain Shrub • Reference Area <br />Herbaceous Cover. A total of 13 transects were taken to quantify <br />herbaceous cover on the mountain shrub reference area. The mean herb- <br />aceous cover was 1.92 percent. Variance was calculated to be 0.91 <br />percent. The required sample size at N80 was determined to be 10.11 <br />samples. The reference area mountain shrub density sample size was• <br />considered to be acceptable. <br />The surtQnary of percent herbaceous cover for mountain shrub in the <br />reference area is shown in Table 1. ~ • <br />Shrub Density. To characterize shrub density on the mountain shrub <br />reference area, 6 transects were taken. The mean shrub density was <br />123.86 shrubs per 50•square meters, Variance was found to be 116.87 The <br />required sample size at N80 was determined to be 0.25 samples. The <br />mountain shrub reference area sample size was considered to be accept- <br />able. <br />The density summary for mountain shrub in the reference area is shown <br />in Table 2. <br />~...,•.:~r, <br />Herbaceous Production. A total of 5 transects were taken to quanity <br />herbaceous cover. on the mountain shrub reference area. The mean herb- <br />aceous production was found to be 1.708 grams per square quarter meter. <br />Variance was found to be 0.344. The required sample size at N80 was <br />determined to be 4.8 samples. The reference area mountain shrub produc- <br />tion sample stze was determined to be acceptable at the 80 percent <br />level. <br />. <br />5 <br />A fic ~c INC. <br /> <br /> <br />
