spaced to maximize their use by wildlife. A live shrub clump site has been established on <br />reclaimed lands in the NE% of Section 22. • <br />Surface Stabilization Measures. The planting of a cover crop will be the principal means of <br />surface stabilization during initial establishment of the perennial vegetative cover. Straw mulch <br />may be used in lieu of a cover crop. Where mulch will be used, the application rate will be <br />approximately one ton per acre. The straw will be anchored by mechanical crimping or tacked <br />with one of the various tackifying compounds available. Mechanical crimping operations will <br />be done on the contour whenever possible. Only clean grain straw that is free of noxious or <br />problem weeds will be used. <br />Reseeding of Previously Seeded Areas. All seeded areas will be periodically monitored for <br />success of perennial vegetation establishment. Soil Conservation Service (SCS) technical guides <br />recommend that a minimum of two years should be allowed before declaring a stand a failure. <br />The heavy annual weed growth during the first, and sometimes second year, make it somewhat <br />difficult to determine the level of success (i.e., adequate establishment of perennial vegetation). <br />At any rate, reclamation experience at the Seneca II Mine shows that an initial heavy weed <br />growth indicates good site characteristics and adequate moisture for establishment and • <br />development of the perennial vegetation. Monitoring at the Seneca II Mine shows that <br />adequate perennial vegetation cover is well established by the second or third growing season, <br />indicating that the perennial species were present prior to that point though not obvious. If <br />reclaimed areas have a low vegetative cover, including annuals, after the first growing season, <br />the area will be evaluated for perennial species density. If the density of perennial species <br />(excluding noxious or problem weeds) is less than one per square foot in a seeded area, the <br />subject area will be reseeded using the appropriate permanent seed mix. Concentrated shrub <br />seeding or planting areas will be exempted from this evaluation since the intent is to keep <br />herbaceous competition at a minimum. <br />Weed and Pest Control. Weed and vegetation surveys conducted on SCC property have <br />identified a variety of weed species. The management of these species varies according to level <br />of infestation and sensitivity of surrounding vegetation. SCC uses an intergrated approach to <br />weed control; management includes prevention, chemical and biological controls. Pursuant to <br />the Colorado 1996 Noxious Weed Law, additional 2003 regulations (35 -5.5 -101 thru 119), and <br />Rule 4.15.1(15), SCC has prepared a comprehensive Weed Management Plan as presented in • <br />Appendix 22 -5. <br />PR -05 <br />36 <br />
