A map of the Lone Pine Gulch Surface Facilities (Map 53A) was used to delineate the <br />Underground Development Waste Pile (UDWP) Area, the Topsoil Stockpile, and the <br />Staging Area. On the map, locations for transects were identified. As the purpose of <br />this study was to evaluate the vegetation cover on these areas, transects were oriented <br />across and/or downslope on each of the three discrete areas. <br />The revegetated disturbance at the Water Tank Site is approximately circular in shape. <br />Ten transects were sampled around the perimeter and through the revegetated area of <br />the Water Tank Site. Transects were sited to represent the variety of vegetation and <br />micro-topography found at the site. <br />Vegetation Cover <br />Vegetation cover was estimated by the use of the point-intercept method. An ocular <br />point frame (ESCO Associates) was used to minimize instrument error and maximize <br />precision and observer accuracy. Cover transects were 25 meters in length, with two <br />sample data points collected at 1.0 meter intervals along the transect on opposite sides <br />of the transect centerline, 1.5m apart. Transect direction was established randomly <br />through the use of a spinner. In no event were transects allowed to extend within ten <br />feet of reclaimed or revegetated area boundaries to minimize impacts from "edge <br />effect." <br />• For statistical purposes, each cover ttansect (comprising 50 data points) served as a <br />sample unit. Data points recorded the first vertical "hit" on vegetation (above or below <br />the instrument), soil (bare ground), rock, or litter. Subsequent "hits" on vegetation <br />were also recorded. Cover data were recorded and reported by individual plant <br />species. The first interception was used to calculate total vegetation cover values. <br />Sample Numbers <br />For the purposes of this sampling, set numbers of transects were established for each <br />area. Four transects were located on the UDWP, three were situated on the Topsoil <br />Pile, and three were located on the Staging Area slope. Locations are identified on <br />Figure 1. Ten transects were located and sampled at the Water Tank Site. Sample <br />locations at the Water Tank Site are represented on Figure 2. <br />Since the purpose of this sampling was to provide quantitative information for a soil <br />loss analysis, it is not required that sampling meet sample adequacy criteria. Minimum <br />sample sizes and standard deviation are reported as an indication of variability of the <br />sampled parameters. Comparisons of sample mean parameter values assume that the <br />sample mean value accurately represents the population mean in all cases. <br />r 1 <br />U <br />-Z- <br />
