<br /> <br />planting program in association with regeneration and reinvosion that will occur as <br />part of the successional patterns of the native plant communities. A combination <br />of direct haul topsoiling and The proximity of undisturbed native plant communi- <br />tieswill provide the basis for these successional trends. <br />Natural catastrophes such as fire or disease that occur in the mountain brush type <br />can effectively remove a large amount of the native vegetation and thus set the <br />community back to some early seral state of succession. While mining impacts <br />are more severe because of greater disturbance, the general pattern of being set <br />back to some early seral state with eventual community development to a stable <br />state is similar to plant communities impacted by natural causes. At the Seneca II <br />Mine, primary succession will occur on spoils thot were not topsoiled and second- <br />ary succession will take place on areas with direct hauled topsoil. While primary <br />succession on the spoils wil{ take longer Than secondary succession on topsoiled <br />areas because of soil development processes and the heavy amount of introduced <br />species, it will nevertheless take place and will be enhanced when livestock are <br />grazed. <br />METHODS <br />In order to document the extent of reinvosion and natural regeneration of shrubs <br />and further understand the successional processes that are occurring in reclaimed <br />areas, it is proposed that shrub densities be estimated and shrub species be identi- <br />fled in several different types of reclamation at Seneca. Three types of reclama- <br />tion will be studied: (I) spoils that have been graded but not topsoiled; (2) spoils <br />that have been graded and topsoiled from topsoil stockpiles; and (3) spoils that <br />have been graded and have had topsoil direct hauled from topsoil stripping areas. <br />The sampling area and sample site locations are shown on the attached map. The <br />following is a breakdown of the sample site designations, sample size, acres, and <br />color code for areas to be sampled. <br />-2- <br />
