DATA ANALYSIS <br />• Data were first analyzed by individual transact and then summarized to <br />provide results by area. Cover data are reported by percent cover for <br />vegetation species, litter, rock and bare ground (Table 1). Shrub density on <br />the reclaimed area is presented as n~ber/hectare and number/acre for <br />individual species (Table 2). <br />In addition to sample adequacy, a t-test for equality was used to determine <br />how similar the reclaimed and Mixed Shrub reference areas were (Table 3). <br />The formula used was: <br />to = <br />• <br />X~ - Xi <br />Sp2 n,) + ni <br />C(n ) (ni)~ <br />Where: to = estimated t-valve which is compared to tabular t-valve <br />xz =mean <br />s variance <br />n = sample size <br />i = reference area <br />~ reclaimed area <br />Sp = m.i + mi <br />n~+ni~- 2 <br />m = (n-1)s <br />RESULTS <br />After reviewing the data collected on both the reclaimed and Mixed Shrub <br />reference areas it can be concluded that no ill affect occurred due to the <br />grazing of cattle on the reclaimed area when compared to the reference area. <br />The total vegetative cover on the reclaimed area was 16.80 percent while the <br />cover on the reference area was only 6.83 percent. <br />The reclaimed area may have been adversely affected by grazing if the cattle <br />had remained on the area for a longer period of time and if significant <br />rainfall had not occurred after grazing had been stopped. <br />It can also be concluded, from the t-test for equality, that the reclaimed <br />and Mixed Shrub reference areas are not equal at this time. <br /> <br />C~ <br />
