SUWECT:'Soils and Vegetation Report DATE: February 18, 1997 TO: Bill Phillips P.O. Box 364 Florence, CO 81226 As per your request, I have summarized into a narrative form my observations of the site we visited. SOILS: The landscape in this area is consistent with the soil mapping units on the attached soils map. The soil mapping units,for this area are the 16 (Cj, Cascajo very gravelly sandy loam, 10 to,4''per cent slopes), the 36 (FcC, Fort Collins loam, cool, ;,to 5 per cent slopes), and the 52 (KC, Kim - Cascajo complex, 2 to''15 per cent slopes). Investigating the site, soil material suitable for surface reclamation, varied from a maximum of 4 feet on'the south side of the area, to a minimum of _6 inches or less, on the west side of the area. The 36 unit (fort Collins loam) would be thiB best unit to obtain'topsoil` from. The Kim component of the 52 (Kim --Cascajo complex) should also supply soil material suitable for reclamation. ,Under this material is a thick layer of well sorted sands and.gragels.. The Cascajo unit (16) and the Cascajo component of the Kim - Cascajo complex are the source of the gravel. All soil material for reconstruction should be removed and stockpiled at another part of the site for future use. At the time of reclamation, the site should be reshaped to at least a 3:1 slope, preferably 6:1. After final grading, the subsoil material should be scarified, or left rough. This will help- bond'the' topsoil to it. Evenly spread the topsoil material about 6 inches thick over the area to be reclaimed. The prepared seed,bed,should be.firm and,-free--of cobbles and stones. All operations should run on the contour to reduce the chances of erosion. See the reclamation plari for more specifics. VEGETATION: Current vegetation on the Loamy Foothill range site are as follows. GRASS AND GRASS -LIKE- blue Grama, red three -awn, cheatgrass, ring muhly, and sand dropseed. FORBS- buckwheat, hairy goldaster, yellow sweetclover, scarlet globe mallow, curly cup gumweed, and groundsel. SHRUBS AND SHRUB -LIKE- walkingstick cholla, fourwing saltbush, plains pricklypear, and broom snakeweed. TREES- None. Current vegetation on the Gravel Breaks range site were very similar with the addition of sideoats grama, indian ricegrass, and fringed sagebrush. POTENTIAL VEGETATION: On the Loamy Foothill range site the potential plant community consists of about 75 to 85 percent grasses, 10 to 15 percent forbs, and 5 to 10 percent shrubs. This site has a rolling grassland aspect with mid - grasses dominating. Western wheatgrass, and green needlegrass dominate the plant community. Blue grama, prairie; O •
