E-4 <br />• <br />• <br />• <br />preparation may consist of light or shallow tillage operations using a <br />combination of disk harrow and spike-tooth harrow. The final tillage <br />treatment will be perrformed by a shallow chisel plow on level contour, or by <br />using a lister or rangeland pitter, The purpose is to leave an uneven, <br />erosion-resistant surface which will aid water infiltration and enhance <br />germination and establishment of seeded and planted species. Any existing <br />vegetation piles will be removed. <br />E.4.4 Seeding Procedures <br />The seed mix application rates and techniques described below are based on <br />previous reclamation experience in the area, as well as consideration of <br />local environmental features of soil, slopes, aspect, elevation, and <br />precipitation. The suggested planting mixture presented below was designed <br />to provide rapid establishment of a diverse array of demonstrably successful <br />species. Use of this species mixture will result in a diverse, effective <br />vegetative cover capable of self-regeneration. The species to be planted <br />are: <br />Species <br />Grasses <br />Agropyron dasystachyum <br />Ag~ro yron desertorum <br />grA opyron elongatum <br />Agropyron riparian <br />Agropyron smithii <br />A_g~rop r~on spicatum inerme <br />grA opyron trichophorum <br />Elymus cinereus <br />mus junceus <br />estuca ovina duriuscula <br />porobolus airoides <br />Forbs <br />Achilles millefolium <br />Hed Sarum boreale <br />eli otus officinalis <br />Seeding Rate <br />Common Name (lbs/acre) <br />Critana thickspike wheatgrass 1.0 <br />Crested wheatgrass 1.0 <br />Tall wheatgrass 1.0 <br />Streambank wheatgrass 1.0 <br />Western wheatgrass 2.0 <br />Beardless bluebunch wheatgrass 1.0 <br />Pubescent wheatgrass 1.0 <br />Basin wildrye 1.0 <br />Russian wildrye 1.0 <br />Hard fescue 2.0 <br />Alkali sacaton 0.1 <br />Yarrow 0.2 <br />Utah sweat vetch 0.1 <br />Yellow sweet=lover 0.5 <br />THIS DOCUM ENT COIJTAINS TRADE SECRETS AND PRIVILEGED, CONFIDENTIAL AND <br />PROPRIETARY COMMERCIAL, FINANCIAL, GEOLOGICAL AND GEOPHYSICAL DATA AND <br />INFORMATION.
