Sagebrush (Artemesia spp.), rabbitbrush(Chrysothamnus spp.), phlox (Phlox spp.), pussytoes <br /> (Antennaria rosea), buckwheat (Eriogonum umbellatum) and stonecrop (Rhodiola spp.). <br /> 5.4.2. Environmental Consequences— Proposed Action <br /> The Proposed Action would remove approximately two acres of vegetation during mining <br /> activities. <br /> 5.4.3. Environmental Consequences — No Action Alternative <br /> The No Action Alternative would keep the surface disturbance in its current state. <br /> 5.4.4. Mitigation Measures <br /> Once mining is complete, re-seed the reclaimed site with native species. <br /> 5.5.1. Affected Environment <br /> Soil information is from the Jackson County Soil Survey, by the Natural Resource Conservation <br /> Service. The survey is not intended for site specific use, but can generalize soil information for <br /> the area, which can be confirmed in the field. Much of the road and the existing disturbed area <br /> are mapped as being in the Brinkert-Morset association (south part of current pit) and Bosler <br /> sandy loam (north part of pit and permit area). <br /> Brinkert-Morset associations' parent material is old alluvium derived from sedimentary rock and <br /> is located on terraces. The surface soil layer is a loam soil of up to five inches in depth. Runoff <br /> classes vary from very high to high, and the association is in Hydrologic Soil Group C. Plant <br /> available water is high, primarily due to the soils' increase in clay with depth to about 20 inches. <br /> Bosler sandy loams formed in old gravelly alluvium and/or outwash, and are located on terraces <br /> and benches. The surface soils are sandy loams up to three inches in depth. The runoff class is <br /> low(hydrologic soil group B), and plant available moisture is low. <br /> Both soil mapping units are rated as being "fair" sources of reclamation material. This rating <br /> assumes that the quarried material was below the soil profile, leaving the subsoil and surface soil <br /> layers to be respread on the site. The soils, however, have very low organic matter in the topsoil. <br /> Organic matter helps the mineral soil by absorbing and retaining moisture and contains essential <br /> nutrients for plant growth. Soil amendments may be necessary for successful revegetation and <br /> soil stability. The Bosler soils are specifically rated as a poor source of topsoil, as the soil is <br /> difficult to respread across a site due to the percent rock fragments in the top 40 inches of soil. <br /> 5.5.2. Environmental Consequences— Proposed Action <br /> The Proposed Action would continue the current gravel mining operations and use of the access <br /> road. Mining the sand and gravel drastically disturbs the overlying soil and can alter the soil's <br /> DOI-BLM-CO-N020-2017-0003 25 <br />
