black and white photographs and waa useful in mapping. Field <br />reconnaissance on the undisturbed sites provided the photographic <br />diagnostic data for mapping the premine plant communities on <br />disturbed areas. <br />Saisting undisturbed areas which represented premining <br />vegetative conditions were selected for each of the four vegetation <br />types based upon aerial photographs, field iaveatigationa of <br />similarities in general appearance, soils, slope, aspect and <br />photographic signature. These areas are approximately three acres <br />in size and were intensively sampled to determine the percent ground <br />cover, current annual aerial production, shrub density, species <br />• composition, and species diversity. Field observations and field <br />data collection were conducted by CYCC in the late summer of 1980. <br />Tranaects along which random points were sampled for plant <br />production and cover were 50 meters in length. Percent ground cover <br />vas determined by placing a 10-point frame along the SOm transect <br />until 100 data points (plant species, litter, bare ground, rock) <br />were recorded. The average for each transect was used as one data <br />point for statistical analysis. Shrub density, (i,e., the number of <br />stems per unit area) vas calculated using a mZ plot frame. Plant <br />production was determined from clipping the annual herbaceous growth <br />in five '~2 quadrats randomly placed along the transect. Plants <br />were clipped at ground level and oven dried before weighing. <br />• Weights were recorded by species. Only the aerial portion of the <br />current annual shrub growth that extended directly above the quadrat <br />2.04-74 <br />
