The dominant species in the <br />potential plant community are Blue grama, Western wheatgrass and Green <br />needlegrass. <br />Climate <br />Precipitation averages around 13" annually with wide fluctuations from year <br />to year. 60 -75~ of precipitation is received between May and October. <br />Soils <br />Refer to soils map and soil descriptions. <br />Reclamation <br />Any existing topsoil should be stockpiled. This stockpile should be <br />protected from wind and water erosion. A good method of protection is to <br />seed the stockpile with a permanent cover. <br />Reclamation will require grading and reshaping the area. Any steep faces <br />need to be blended into a gradual slope (3:1 or better) prior to seeding. <br />Reclamation should begin as quickly as possible after mining activities in <br />the area cease. <br />Refer to seeding recommendation for seeding specifics. Mulching will have <br />to accompany reseeding to limit any erosion from rain or wind. <br />The area will need to be closed to grazing for 2-3 years after seeding to <br />allow for seedling development. <br />Sincerely, <br />.~Ati~ <br />John Fusaro <br />Range Conservationist <br />
