. /J ,,,toot of epaatw.aa, , r 1 Ruth Gray Skelton Inc. Harwood, CO 81423 Dear Ruth: _ I visited the site regarding the existing gravel mining operation: i Sec 13, T45N, R13W and San Miguel ~'. T45N, R13W. F' ~ Hx'_stin Ve etation i• g K HIBiT B-1 age 1 March 16, 1988 potential expansion of the tdcntrose County, SW~,idW?~ County, NWT, Sld~, Sec 13, • The plant community is basicly a sagebrush community. The ` Wyoming bigsage makes up approximately 45 ~ of the vegetative cover where it dominates. In these areas the grasses make up approximately 30 percent of the cover and are: Indian ricegrass, Mutton grass, Bottlebrush squirltail, and~Galetta. There are areas where surface disturbance has occured (old airstrip and vehicle traffice) and there is evidence of reseeding. Here the plant community is approximately 80 percent grass: Crested wheatgrass, and those which appeared on the previously mentioned site. Snakeweed, green rabbitbrush and wyoming bigsage accure here and make up approximately 15 S of the plant community. Soils: A cooy of the soil trap is attached as are the narrative descriptions. Note that on thb soil map is shown the location of existing gravel mire operations on the same soils. The soils are Radersburg and .Callan. Revegetation: Topsoil will vary in depth. In some areas it will be difficult to save due to shallowness to gravel. an other areas it will be thick enough to save - in fact can be 5 Faet or more deep. Where possible, topsoil should be saved by stockpiling. These piles should be seeded during early winter (after October 15) to keep the soil in place until used for reseeding. Seed with Western wheatgrass using the rate of 16 pound of Pure Live Seed per acre. Seed companies can figure bulk seed required to get the PLS recommended rate. When reclaiming, the area should first be rough leveled to natural grade; topsoil then spread over the area at a depth of 4 to 6 inches; seeding is the final step.
