Sample sites will be located in the field using a I inch equals 400 <br />feet topographic map. <br />A 50-meter transact will be randomly oriented from each sample site point. <br />Shrubs rooted within a I meter by 50 meter rectangular quadrat located along the <br />50 meter transact will be counted by species and corresponding heights esti- <br />mated. Shrub species not occurring within the quadrat but present on the site will <br />be noted. Data will be presented by sample site number, shrub numbers in the 50 <br />meter square plot and shrub numbers per acre and per hectare. Sample means and <br />standard deviations will also be provided. <br />Sampling will take place in late July and report preparation wi{I be completed by <br />early fall. <br />Results of this study will show The extent and pattern of natural regeneration and <br />reinvasion by various shrub species in reclaimed areas. Since the time of topsoil <br />and seeding is known, estimates of minimum densities attainable at the bond re- <br />lease period may be possible. Benefits of direct-hauled topsoil pertaining to shrub <br />regeneration will be shown and compared to the other two types of reclamation <br />sampled. Finally, density estimates will provide data for establishing an aS;tain- <br />able shrub density number in reclamation at Seneca II. <br />-3- <br /> <br />Sample Size Acres <br />. m r..~. ,....~ <br />
