Species include: rabbits, eagles, hawks, owls, coyote, songbirds, small mammals and reptiles. Mule deer and elk use the area during winter and spring. 3. Watershed (Hydrologic Interpretation) Soils in this site are grouped into "B" hydrologic group, except for Hagerman and Progresso soils which are "C ", as outlined in the "Soils of Colorado Loss Factors and Erodibility Hydrologic Groupings 1979" handbook. Field investigations are needed to determine hydro- logical cover conditions and hydrologic curve numbers. The hydro- logic curve number for group B soils are about 61 and group C is about 74, when the hydrologic conditions are good, as shown in "Peak Flows in Colorado" handbook. Refer to SCS National Engineering Handbook, Section 4, to determine runoff quantities from the curves. 4. Recreation and Natural Beauty This site has fair to poor aesthetic appeal and natural beauty. During exceptional rainfall years, a profusion of flowering plants appear. 5. Threatened and Endangered Plants and Animals (At the present time none are identified). 6.
