4.0 RECOMMENDATIONS <br />In the interest of attempting to increase species diversity and reduce competition from cheatgrass, <br />Cedar Creek rernmmends that the North Decline Area be treated with a cheatgrass herbicde, Oust or <br />preferably Plateau, very early during the spring of 2005". After several weeks, afollow-up interseeding <br />should take place. Application of the herbicide must coincide with the initial °green-up" of the cheatgrass <br />in early spring prior to any other speces breaking domwncy. The interseeding should be heavily <br />weighted toward cool and warm-season grasses and perennial fortis /sub-shrubs, which are presently <br />absent or in kwv abundance throughout much of the revegetation. The interseeding should occur by <br />pedestrian means using heft mounted /hand operated seed distributors ("whiriygigs'~. Mechanical <br />measures will disturb the soil surface thereby further encouraging cheatgrass emergence. The 17.7-aae <br />North Decline Area could be interseeded In this manner in 10 to 12 man-hours. A recommended mix for <br />this interseeding effort would be as follows: <br />S ies Lbs acre Seeds / ft <br />Warm-season Grasses <br />Galleta Pleuraphis jamesii 2.0 7.30 <br />Alkali sacaton Sporobolus airoides 0.5 20.18 <br />Cool-season Grasses <br />Crested wheatgrass Agropyron cris[atum 1.0 4.59 <br />Thickspike wheatgrass Elymus lanceolatus ssp. !. 2.0 7.07 <br />Russian Wildrye Psathyrostachysjunceus 1.0 4.02 <br />Sandberg Bluegrass Poa sandbergii 0.25 5.31 <br />Great Basin Wildrye Elymus cinereus 0.5 2.98 <br />Perennial Fortis & Subshrobs <br />Palmer penstemon Penstemon Palmeri 0.25 7.00 <br />Prostrate kochia Kochia prostra[a 1.0 9.36 <br />GardnerSaltbush Atrip/exgardneri 1.0 2.56 <br />Winterfat Krascheninnikovia lana[a 2.0 2.60 <br />Shrubs <br />Shadsole Atriplex confertifolia 0.5 0.74 <br />Black oreasewood Sarcobatus vermiculatus 0.5 2.41 <br />TOTAL 12.5 76.12 <br />In the interest of increasing plant cover, especially wane-season grass cover, on some of the thinner <br />areas of the South Fan and 2 West Portals areas, interseeding with the above seed mix is recommended <br />in the spring of 2005. It is estimated that approximately 0.5 acres of revegetation should be seeded by <br />Cedar Creek should be consultedrf Snowcap decides to pursue this coarse of action as use of these herbicides is <br />very time critical. Application at the wrong time or under the wrong conditions may result in severe damage to the <br />e>asting desirable revegetation. <br />SNOWCAP COAL COMPArrY Page 16 Revegetatlon Evaluatbn 2004 <br />
