• <br /> or other conditions, will be offset by portions with higher plant cover. <br /> Revegetation can generally be considered successful when native perennial vegetation within <br /> reclaimed portions represents about 5% vegetative cover and all native vegetation, both <br /> perennial and annual, is stable. Stability is determined by the presence of plants setting seed <br /> and the presence of seedlings. Generally, adequately reclaimed mines are able to meet <br /> standard success criteria within two to three years under normal rainfall conditions. Therefore, <br /> the revegetation success at the Mesita Hill Mine will be evaluated for the purposes of this report <br /> with the concept of a stable, self-sustaining revegetation represented by a stable native <br /> perennial species cover of at least 5% on the reclaimed portions of the mine site. Stability is <br /> defined by the presence of plants setting seed and the resultant seedlings continuing with <br /> growth and reproduction. <br /> 4.0 CURRENT RECLAMATION STATUS <br /> The mine site underwent a reclamation effort in October and November of 2008 including partial <br /> slope reduction on the north pit, redistribution of remaining stockpiled topsoil, ripping of the <br /> backfilled central area surface, and seeding of these areas, i.e., seven years prior to this 2015 <br /> survey. Mine disturbance areas with re-spread topsoil cover include the perimeter of the mine <br /> disturbance (Appendix A, Figure 2). Topsoil placement was spread across the site as identified <br /> below: <br /> Area Topsoil placement <br /> Northern portion Mosaic of topsoil around outer portion <br /> Northeast portion Majority topsoil covered <br /> Main Pit—north slope Upper portion with topsoil <br /> Main Pit—east slope Upper portion with topsoil <br /> Main Pit—south slope Upper portion with topsoil <br /> Main Pit—west slope No topsoil <br /> Northwest portion Mosaic of topsoil <br /> Western portion Mosaic of topsoil around outer portion <br /> Southwest slope Topsoil covered in upper portion <br /> Southern portion Topsoil covered <br /> Southeastern hillock Topsoil covered <br /> Central flat No topsoil <br /> 3 <br />
