• an estimate of the area covered by each of the major <br />components (vegetation, bare ground and litter-rock) within <br />_ the quadrat and discounts the layered overlapping effect <br />explained above. Cover estimated in this way always totals <br />-- 100. The value of calculating Total Cover is that an estimate <br />of bare ground susceptible to erosion is determined and can <br />be used in evaluating potential erosion of reclaimed land <br />_ as compared to pre-mining conditions. These data provide <br />one of the parameters that can be used in a universal soil <br />loss equation. <br />I-2.4 Production <br />_ The above-ground biomass comprising the understory within <br />• each 0.5 meter squared quadrat was clipped between July 28 <br />and August 2, 1981 by life forms (perennial grasses, grasslike <br />- species, forbs, half-shrubs, shrubs less than one inch stem <br />diameter, annual grasses and annual forbs) which were placed <br />in separate bags. Samples were oven-dried at 80 degrees C <br />_. for 24 hours, weighed and weights recorded on data sheets. <br />I-2.5 Density <br />Density for shrubs and trees greater than 1.0 inch stem <br />diameter was estimated using the point-centered quarter method <br />for randomly distributed individuals.
