The mature shrub clump transplant areas will vary from .5 to 1.0 acres in size. The transplant azea • <br />will contain approximately 100 shrub clumps per acre. Transplant areas will be sufficiently spaced to <br />maximize their use by wildlife, <br />Surface Stabilization Measures. The planting of a cover crop will be the principal means of surface <br />stabilization during initial establishment of the perennial vegetative cover. Straw mulch may be used <br />in lieu of a cover crop. Whenever mulch is used, the application rate will be approximately one ton <br />per acre. The straw will be anchored bq mechanical crimping or tacked with one of the various <br />tacki£ying compounds available. Mechanical crimping operations will be done on the contour <br />whenever possible. Only clean grain straw that is free of noxious or problem weeds will be used. <br />Hydtomulching has been discussed previously. <br />Reseeding of Pr_ evously Seeded Areas. All seeded aeeas will be periodically monitored for success of <br />perennial vegetation establishment. Soil Conservation Service (SCS) technical guides recommend <br />that a minimum of two years should be allowed before declaring a stand a failure. The heavy annual <br />weed growth during the first, and sometimes second year, make it somewhat difficult to determine <br />the level- of vegetation success (i.e., adequate establishment of perennial vegetation}. At any rate, <br />reclamation experience at the Seneca II Mine shows that an initial heavy weed growth indicates good • <br />site chazacteristics and adequate moisture for establishment and development of the perennial <br />vegetation. Monitoring at the Seneca II Mine shows adequate perennial vegetation cover is often <br />well established by the second or thud growing season, indicating that the perennial speces were <br />present prior to that point though not obvious. If reclaimed areas have a low vegetative cover, <br />including annuals, after the first growing season, the azea will be evaluated for perennial gpecies <br />density. If the density of perennial species (excluding noxious or problem weeds) is less than one per <br />squaze foot in a seeded azea, the subject azea will be reseeded using the appropriate permanent seed <br />mix. Concentrated shrub seeding ox planting areas will be exempted from this evaluation since the <br />intern is to keep herbaceous competition at a minimum. <br />Weed and Pest Control. Weed and vegetation surveys conducted on the Yoast and other <br />SCC properties have revealed many weed species. The management of these species varies <br />according to level of infestation and sensitivity of surrounding vegetation. SCC uses an <br />integrated approach to weed control on property owned in Routt County, Colorado. <br />Management includes prevention, chemical, mechanical and biological controls. Pursuant <br />to the Colorado 1996 Noxious Weed Law and additiona12003 regulations, (35-5.5401 through <br />119), SCC has prepared a comprehensive weed management plan, See Appendix 73-14, Weed • <br />Management Plan, for a complete copy of the plan. <br />MR-53 13-28 Revised 12/05 <br />
