<br />DATA ANALYSIS <br />Data were first analyzed Dy 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 for <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 formula used xas: <br />to = <br />Xj - Xi <br />Spz nj + ni <br />C(n')(ni)~ <br />0 <br />Where: to =estimated t-valve xhich is compared to tabular t-valve <br />x2 =mean <br />s variance <br />n = sample size <br />i = reference area <br />j2 =reclaimed area <br />Sp mi + mi <br />nj+ni~-2 <br />m = (n-1)s <br />RESDLTS <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 xas 16.60 percent xhile 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 />
