The mature shrub clump transplant areas will very from .i to 1.0 acres in size. the <br />transplant area will contain approximately 100 shrub clumps per acre. Transplant areas • <br />will be sufficiently spaced to maximize their use by wildlife. <br />Surface Stabilization Measures. The planting of a cover crop will be the pri nclpal means <br />of Surface stabili2a[ion during initial establishment of the perennial vegetative cover. <br />Straw mulch may be used in lieu of a cover trop. whenever mulch is used, the application <br />rate will be approximately one ton per acre. The straw will be anchored by mechanical <br />crimping or tacked with one of the various tackifying compounds available. Mechanical <br />Crimping operations will be done on the contour whenever possible. Only clean grain straw <br />that is free of noxious or problem weeds will be used. Rydromulching has been discussed <br />previously. <br />Reseeding of Prevouslv Seeded Areas. All seeded areas w~i l 1, be periodically monitored for <br />success of perennial vegetation establishment. Soil Conservation Service (SCS) technical <br />guides recommend that a minimum of two years should be allowed before declaring a stand e <br />failure. The heavy annual weed growth during the first, zind sometimes second year, make <br />it somewhat difficult to determine the level of vegetation success (i.e., adequate <br />establishment of perennial vegetation). AC any rate, reclamation experience at the Seneca • <br />II Mine shows that an initial heavy weed growth indicates good site characteristics and <br />adequate moisture for establishment and development of the perennial vegetation. <br />Monitoring at the Seneca 11 Mine shows adequate perennial vegetation cover is often well <br />established by the second or third growing season, indicating that the perennial species <br />were present prior to that point though not obvious. If reclaimed areas have a low <br />vegetative cover, including annuals, after the first growing season, the area Mill be <br />evaluated for perennial species density. If the density of perennial species (excluding <br />noxious or problem weeds) is less than one per square foot in a seeded area, the subject <br />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 <br />keep herbaceous competition at a minimum. <br />weed and Pest Control. A number of noxious weeds occur in [he region surrounding [he <br /> <br />Seneca II Mine. Specifically, the following noxious needs (as listed in Section v, CMLRD <br />Guideline for the Management of Noxious weeds on Coed Mine Permit Areas) have been <br />identified on the mine permit area: <br /> s <br />13-28 Revised 01/15/93 <br />
