Af d Ar a S mnr];n¢ Des +_Qn for Cover <br />Cover was determined using point samples along randomly located <br />transects. A 1-meter point frame containing 10 points at 10 cm intervals was <br />used. For each point, The first vertical rod hit on vegetation, litter, rock <br />or bare ground was recorded. Along a 100-meter transect, the point frame was <br />placed every 10 meters to obtain 100 sample points per transect. Transects <br />were randomly located within each mapping unit. Sampling proceeded until an <br />adequate sample size had been obtained for each mapping unit. Each 100 meter <br />transect was considered as a single sample. <br />All control areas were located so that they would not be disturbed <br />during the life of the mine. The nearest control site to any mining activity <br />is the Subirrigated Shrub control site. This control site is approximately <br />1000 feet from the bottom of the west Aidge mining area and is across Trout <br />• Creek from the mining area. The next closest control site to mining <br />activities is the Oak (Mountain Shrub) control site. It is located <br />approximately 2800 feet north of the northern most affected boundary of the <br />Moffat Area. <br />Sites for control areas were selected on the basis of species present <br />and similarity of cover based on pre-sampling of affected and control areas. <br />The control areas were able to be placed within their corresponding vegetation <br />types with the exception of the Oak (Mountain Shrub) control area. The Oak <br />control area was placed within a portion of the Sagebrush/Snowberry vegetation <br />unit because mining activities were anticipated to affect all lands containing <br />the Oak vegetation unit. Although the Oak control area was not placed within <br />its corresponding vegetation type, a sufficient area within the Sagebrush/ <br />Snowberry community having the Oak vegetation type characteristics existed to <br />enable the establishment of an Oak control area. All of the control areas <br />were at least two acres in size. <br />Production data were obtained by randomly locating 0.5 M x 1.0 M <br />quadrats within the control area. Harvesting, drying and weighing procedures <br />• were the same as those employed in the affected areas <br />2.4-10 November 9,1990 <br />
