d. Major Poisonous PLANT LIVESTOCK COMMON NAME AFFECTED broom snakeweed cattle & sheep 2. Wood Products Plants to Livestock TYPE POISONING Cumulative, selenium when growing on cretaceous or eocene shales page 7 #326 SEASON SERIOUS when forage is scarce and broom snakeweed greater than 10% of diet This site has no potential for growing wood products commercially. Living snowfences and windbreaks may be grown with supplemental' irrigation water. Species to consider for these purposes are juniper, pinyon, and Russian olive. 3. Wildlife Values Range use that encourages shrub growth will improve critical winter habitat for mule deer. This however may not coincide with maintaining or improving range condition. In general, all range practices that promote good range use and maintain or improve range condition will improve or maintain wildlife habitat for all species. 4. Hydrological Interpretations Soils in this site are grouped into "A" and "B" hydrologic groups, as outlined in the Soils of Colorado Loss Factors and Erodibility Hydrologic Groupings handbook. Field investigations are needed to determine hydrologic cover conditions and hydrologic curve numbers. Refer to Peak Flows in Colorado handbook, and SCS National Engineering Handbook, Section 4, for hydrologic curve numbers and determining runoff quantities. The full spread of the natural plant community canopy is about 40 to 50% when in excellent condition. As range condition declines, canopy cover declines rapidly. This normally does not increase runoff on this site due to surface soil textures. However rain drop splash erosion will increase as more surface soil is devoid of cover.
