• 3.0 RANGE CONDITION AND SUCCESSIONAL STATUS OF VEGETATION TYPES <br />Neither the Pinyon/Juniper Woodland nor the Mountain Shrubland represents <br />significant grazing resources, except for those parts of the Mountain <br />Shrubland which have been burned and/or otherwise cleared. In the latter <br />areas, the woody component has not re-established the complete dominance <br />it holds in the other parts of the mapping unit. Grasses and fortis com- <br />prise a substantial portion of the cover and production of the area. <br />Species composition resulting from the disturbance has been so altered <br />that range condition would be deemed "fair." "Fair" range condition would <br />be assigned because of the shrub component, which provides as much as <br />35 percent of total composition and brings the percent of original Iclimaxl <br />composition (Brushy Loam range site, SCS Southern Rocky Mountain Land <br />Resource Area) above the 25 percent level by itself. The herbaceous <br />component is composed of species colonizing the burned area and not <br />remnants left after years of grazing pressure. <br />The remainder of the Mountain Shrubland is not a significant grazing <br />resource because of the dense shrub cover and the lack of herbaceous <br />growth. The dense shrub cover may be the result of abuse in a stand once <br />more open in structure and with greater herbaceous production. The current <br />vegetational composition apparently is stable, with no obvious tendency <br />for development of openings in the shrub cover that would allow more <br />• herbaceous growth. <br />In the Pinyon/Juniper Woodland, the lack of herbaceous understory <br />growth may likewise be the result of abusive grazing in the past. The <br />type has very little utility as a grazing resource for domestic animals <br />because of the scarcity of herbaceous (ants, especially grasses, in the <br />areas of dense canopy cover and the steepness and rockiness in the more <br />open sites. At present there is no obvious successional trend toward <br />more or less woody cover; probably no great change can occur until the <br />death of some of the current over story dominants. At that time, grazing <br />pressure, the proximity of herbaceous seed sources, and climatic condi- <br />tions would determine whether herbaceous vegetration could maintain a <br />presence in competition with the offspring of the current woody dominants. <br /> <br />-6- <br />
