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 number/hectare and number/acre Por <br />individual species (Table 2). <br />In addition to sample adequacy, a t-test for equality xas used to determine <br />how similar the reclaimed and Mixed Shrub reference areas were (Table 3)• <br />The Pormula used xas: <br />to = <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 /> x2 =mean <br /> s = variance <br />I n = sample size <br /> i = reference area ' <br /> JZ =reclaimed area <br />I Sp m3 + mi <br /> n~+n~-2 <br /> m (n-1)s <br /> RESULTS <br /> After reviewing the data collected on both the reclaimed and Hixed 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 />I 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 oP 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 Lhe reclaimed <br /> and Mixed Shrub reference areas are not equal at this time. <br /> <br /> <br />1 <br />1 <br />
