3. Revegetation Plan <br />Prior to seeding, the topsoil will be scarified or plowed to relieve any compaction during <br />placement. <br />The seed mix to be applied to the reclaimed Vagneur Pit has been developed in cooperation with <br />Pitkin County, CSU Extension and NRCS. The dry rangeland seed mix will be applied to the <br />slopes of the pit as well as the flat areas on the perimeter of the pit to include the pit floor. This <br />seed mix has been developed based on a post-mining use of dry rangeland. It will be more than <br />adequate to control erosion for the site and provide good cover. Once sufficient ground cover is <br />established sage seeds will be planted along the slopes as per the seed plan. <br />The species that make up the revegetation seed mix are as follows: <br />RECLAMA TION SEED MIX <br /> % MIXTURE SEED SEED <br />COMMON NAME LATIN NAME (BY PLS/ACRE PLS/ACRE <br /> WEIGHT DRILL BROADCAST <br />Western Agropyron smithii 17 5 10 <br />Wheat grass <br />Thickspike Agropyron 17 5 10 <br />Wheat grass das stach um <br />Slender Wheat Elymus 17 5 10 <br /> trach caulus <br />Green Needle grass Sti a viridula 13 3.75 7.5 <br />Indian Ricegrass Oryzopsis 9 2.5 5 <br /> h menoides <br />Mountain Brome Bromus 13 3.75 7.5 <br /> mar inatus <br />Rabbitbrush Chrysothamnus 7 2 4 <br /> nauseosus <br />Serviceberry Amelanchier 7 2 4 <br /> alnifolia <br />TOTAL 100 29 58 <br />1. Plant sage in late fall, after grasses have become established and weed control applied, <br />broadcast only. Recommended species is Mountain Big Sage; Scientific name - <br />Artemesia tridentate ssp. vaseyana. Sage seed shall be applied at the rate of 10 to 121b/ac <br />pls. <br />Certified weed free mulch will be applied at the rate of 30001bs per acre and will be crimped <br />into the surface since all slopes are 3H:1 V or milder. <br />Vagneur Pit June 07 E-4
