The <br />Wyoming bigsage makes up ,approximately 45 ~ of the vegetative <br />cover where it dominates. In these areas the grasses make up <br />approximately 30 percent of the cover and are: Indian rice grass, <br />[+lut-:n grass, Bottlebrush squirltail, and-Galetta. There are <br />area: where surface disturbance has occured (old airstrip and <br />vehicle traffice) and the:^e is evidence of reseeding. Here the <br />plant community is approximately 80 percent grass: Crested wheatgrass, <br />and those which appeared on the previously mentioned site. <br />Snakeweed, green rabbitbrush and Wyoming bigsage accure here and <br />make up approximately 15 'x of the plant community. <br />Soils: <br />A copy of the soil trap is attached as are the narrative descriptions. <br />Note that on thb soil map is shown the location of existing gravel <br />mine operations on the same soils. The soils are Radersburg and Collar,. <br />Revegetation: . <br />Topsoil will vary in depth. In some areas it will be difficult to <br />save due to shallowness tp gravel. In other areas it will be thich <br />enough to save - in fact ~:an be 5 feet or more deep. Where possible, <br />topsoil should be saved b;~ stockpiling. These piles should be <br />seeded during early winte;^ (after October 15) to keep the soil in place <br />until used for reseeding. Seed with Western wheatgrass using the <br />rate of 16 pound of Pure Live Seed per acre. Seed companies can <br />figure bulk seed required to get the PLS recommended rate. When <br />reclaiming, the area shou:Ld first be rough leveled to natural grade; <br />topsoil then spread over the area at a depth of 4 to 6 inches; <br />seeding is the final step.
