Included is information on <br />vegetation, reseeding, and weed control. <br />There are no prime farmlands located within the boundaries of <br />area. Soils found there are class V, VI and VII soils. In g <br />only Class I and II lands are considered prime farmland. <br />The Jodero-Colo and the Monte soils are considered to be good <br />of topsoil. The Alamosa soil is considered a poor source of <br />mainly due to wetness and flooding problems. A soils map and <br />are enclosed for your use. <br />tage <br />oils, <br />permit <br />ces <br />il, <br />riptions <br />A currenC list of the plants found on the site is attached. Sin a the <br />site has been damaged by past mining and overgrazing, no attempt has been <br />made to correlate this vegetation with the Foothill Loam range s to <br />(copy attached}, <br />During the mining process the topsoil should be stripped to a d <br />20 to 24 inches. The soil should be stockpiled for reuse after <br />has ceased. While the operation is active the stockpiled soil <br />be protected from erosion and weeds. This could be accomplishe <br />a seeding of streambank wheatgrass broadcast at a rate of 22 po <br />pure live seed per acre. Protection could also be gained if th <br />were covered with loose straw at a rate of 500 to 800 pounds pe <br />acre. <br />After the mining operation has ceased the areas should be Smoot <br />All roads and driveways should be well chiseled or otherwise bt <br />up so that water and roots may penetrate the soil. Any areas F <br />and/or chemical spills should be'neutralized or removed from tt <br />before reclamation. Those areas should receive extra attentior <br />improve success. <br />Ith of <br />lining <br />ould <br />with <br />stockpile <br />surface <br />ed out. <br />.th oil <br />site <br />to <br />O Tna Sod Conservation Service ~ SCS-AS-1 <br />U is an agency of me 10-79 <br />DeOarlm enl of Agric ull ure <br />
