• 10 percent of the unit. Permeability is slow in the Penrose soil, and moderately slow in the Mingwet-Wiley soil and available water capacity is very low. Effective rooting depth is 4 to 14 inches. Runoff class is from medium to low, and the hazard of water erosion is very slight. The potential plant community of the Mingwet-Wiley and Penrose soil type is mainly juniper and an understory of sideoats grams, blue grams, Little bluestem, Buffalo grass and western wheatgrass. The potential production of native understory vegetation in normal years is about 1200 pounds of air-dry vegetation per acre. If the condition of the understory deteriorates, blue grams, yucca, broom snakeweed, and other forbs increase. The transition between the Penrose soil and the Mingwet-Wiley soils is not very different. Both soils are typically used as rangeland. The Penrose soil is shallow and well drained. It formed in thin, calcareous, loamy materials weathered in place from limestone and interbedded limy materials. Slopes range from 1 to 65 percent. The Mingwet soil is moderately deep, well drained soil. It formed in loess and residuum derived from calcazeous shale and limestone. Slopes range from 1 to 10 percent. The surface layer is typically channery loam about 0 to 6 inches thick. The soil is moderately alkaline. Permeability is very slow in the Penrose and Ninqwet soil. Available water capacity is very low. Effective rooting depth is 4 to • 14 inches. Runoff is moderate to low, and the hazard of water erosion is very slight. The entire area has been grazed by cattle over the years using rotation grazing so the range condition is good considering the drought over the past several years. Erosion has not occurred over the years, and the amount of available soil for reclamation will be good. (bl Permanent Man-made Structures There is a stock pond approximatey 100 feet west of the Buffalo Stone Quarry. The pond collects water that drains from the southwest of the quarry. No water from the quarry drains into the pond. The rock quarry will have no effect on the stock pond. The location of the stock pond is shown on Attachment 1. (c) Water Resources No streams, springs, lakes, ditches, reservohs, or aquifers would receive drainage from the affected azea. No information is available from publications or monitoring data regazding flow rates, water table elevations, or water quality conditions. (d) Wildlife The Colorado Division of Wildlife (CDOW) has described the wildlife of the area (please see Attachment 4 for a copy of the CDOW letter from which the following • excerpts were taken).
