Site Description (cont) Exhibit B <br />VEGETATION INFORMATION <br />1. Current cover percent is: 45 to 65% <br />2. Topsoil depth on site averages: 0 to 7 inches <br />3. Seeding dates recommended: October 15 to May 1. <br />4. Fertilizer, if needed: Phosphate @ 40 lb/ac and nitrogen @ 40 lb/ac. <br />5. Seeding recommendation for area: <br />Non-irrigated grass seed recommendation <br />Seed Rate PLS/acre <br />Western Wheatgrass (Arriba) 10.0 <br />Sideoats grama (Vaughn) 6.5 <br />Blue Grama (Lovington) 0.5 <br />Winter Wheat 25.0 <br />42.0' <br />This seed mix and rates was prepared by the local NRCS office <br />at our request for us on other mining operations in the area. It <br />has proven successful on other sites in the vicinity of this mine. <br />The seed will be drilled where possible and doubled if broadcast. <br />The site is currently part of a terrace deposit above the Huerfano <br />River located in a Loamy Plains range site unit north of <br />Walsenburg, Colorado. It has no special or unique characteristics <br />with mostly grass, cactus and sage brush covering the area. <br />Between the current mining area and the county road is an area <br />that was mined sometime in the past. It appears that whoever mined <br />the area worked the face of the deposit back from the county road <br />until their project ended. We suspect this area was mined to <br />provide material for I-25 which lies 1.5 miles east of the mine. <br />This area has no topsoil on it and the vegetation has more cactus <br />and sage brush then the surrounding rangeland. Average annual <br />production is approximately 300 pounds per acre. The plant commu- <br />nity is 60 to 75 percent grasses and 25 to 40 percent cactus and <br />brush. <br />The species of vegetation found on the old mine site are Blue <br />grama, Western wheatgrass, Sand dropseed, Little bluestem, Indian <br />rice grass and Sideoats grama. These grass species makeup 85% to <br />90%, by weight, of the vegetation found on the site. Ground cover <br />is sparse in this area in comparison with the undisturbed areas <br />south of the old mining face. <br />On the areas that were not disturbed by mining the vegetation <br />consists of mostly grass with some cactus. Average annual produc- <br />tion is approximately 1,000 pounds per acre. Grasses make up <br />approximately 90% of the vegetative cover and the plant community <br />is 80 to 90 percent grasses and 10 to 20 percent cactus and brush. <br />This area has a good grass cover because the site has not been <br />grazed for quite some time. <br />The species of vegetation found on the site are Blue grama, <br />Gallate, Western Wheatgrass, Sand dropseed, Buffalograss, and <br />Sideoats grama. These grass species makeup 85% to 90%, by weight, <br />of the vegetation found on the site. <br />NOTE: 1/ Indicated rate if drilled. The mixtures will be doubled if broadcast. <br />20
