PotF~ii i::} •.~,•gctation is Sandreed, <br />sand bluestem, big hluestem, needle & thread, sidevat=_ yr~ma, little <br />bluest ern, switchgrass, sand sage & yucca. <br />Presently, this area has very little permanent vegetation. The <br />present vegetation is mainly sand sage, blowout grass, three awn and <br />. annual weeds. Generally anything that can be done would be an <br />improvement. <br />. I would reccomrnend that mining be limited to small areas, no more <br />than 5 to 10 acres in a hlocl;. The plan is tv remove the high hills <br />for use as fill material off site. With the leveling of these hills, <br />• the erosion hazard will be lowered from the present condition. The <br />reclama':ian plan should include slopes no Steeper than 3:1. A mulch <br />of straw or feedlot manure may be desireahle, when reseeding. <br />.
