Before the topsoil is replaced and re-spread, regraded land will <br />be scarified or otherwise treated, if necessary, to eliminate slippage <br />surfaces and to promote root penetration. Topsoil will be replaced and re- <br />spread to achieve an approximate uniform thickness. <br />Based upon a review of published reports dealing with range <br />seeding and disturbed land re-vegetation, numerous adapted and native <br />species will be included in the re-vegetation mixture. The species have <br />been selected for their ability to become established on difficult sites <br />and to provide a diverse, effective and permanent vegetative cover with the <br />seasonable variety, succession, distribution, and regenerative capabilities <br />native to the area. The proposed seed mixture is: <br />Western Wheatgrass 15% <br />Crested Wheatgrass 10% <br />Intermediate Wheatgrass 10% <br />Pubescent Wheatgrass 10% <br />Small Burnet <br />ager Meadow rom 10% <br />10% <br />Sherman B' Bluegrass 10% <br />Ladack Alfa 5% <br />Timothy 5% <br />Orchard Grass 5% <br />Slender Whe rass 5% <br />Cicer Mil bate 5% <br />After the topsoil has been replaced, the affected areas will be <br />broadcast seeded at a seeding rate of 20 pounds per acre. If the soil <br />surface has become encrusted before seeding can occur, the soil surface <br />will be scarified or a rangeland drill will be used for seeding.. <br />-13- <br />
