Gra_ zing Thia site provides early summer forage for cattle, cheep, horses, antelope and small marmals. It has leaser value as spring forego. as the key species are later in growing. The dominant grass species alkali sacaton, galleta and blue grams are excellent forage in summer and fall. In addition, alkali sacaton and blue grams retain their nutritive value after maturing, therefore.making excellent winter fcrage, however, the feeding of pioteia suD9lements is necessary to meet the ~equiremente of the grazing animal. Vegetarive palatability will influence proper use considerations. The season, kind of grazing animal, past grazing use, and associated plans species will directly influence the variation in animal pre- ference for Poragae under various climatic conditions. Continuosa year-long grazing or grazing fron April tc September by cat~le cause alkali sacaton and western wheacgrssc to be replaced by ring muhly, red threeavn, galleta and blue grams. A system of de- ferred grazing, which varies the season of grazing use in pastures during surcessive years, is needed to maintain s healthy well- balanced plant community. Rest during differen*_ seasons cf the year •~- benefits different plants. Summer rest (June - September) benefits ( wars-season plants such ae alkali sacaton, D1ue grave ar_d galleta. Spring rest (April - July) benefits cool-season plants such as western whestgreas, Indian riuegrass and needleandthread. Alkali sector. will benefit by defermene From early Hay eo the end of July. Deferment during late winter and spring redu~:ae competition be_veen grazicg animals for palatable shrubs and forbs. 2. Hood Products Wood products sre not produced on CD is site. 3. Habitat for Hildlife This range Bite provides a habitat which supports a resident animal community that Ls characterized by cottontail, antelope, jack rabbits, rattlesnakes, reptiles, and other animals. 4. 9ydrological Tr.cerpretations Soils in this site are grouped into 'D" hydrologic group, as out- lined in the "SO11s of Colorado Loae Faetora and Ernd±biliry HYdroiogic Groupings 19'9" handbook. Field investigations are needed to determine hydrological cover ccnditiona and hydrologic curve numbers. The hydrolagle curve lumber for Croup D so11 is about 80 when hydrologic conditions are good, es shown Sn "Peak . Flows in Colorado' Fnndbook. ~.
