<br /> <br />5. Vegetation <br /> <br />Alpine vegetation OCcurs along the crest of the <br />mountain range with spruce/fir, Douglas-fir, and <br />ponderosa pine at lower elevations. The majority (83 <br />percent) of the western slope of the Sangre de <br />Cristo Range is non-forested, and only about 17 <br />percent of the area is forested. The nonforested <br />area consists of rock, alpine, and brushland <br />vegetation. The eastern side of the range (San <br />Isabel) is predominantly forested with only about 28 <br />percent of the area in a nonforested condition. <br />These forested areas generally occur along the lower <br />elevations adj acent to the eastern WSA boundary. <br />Riparian vegetation occurs adjacent to the perennial <br />streams. <br /> <br />6. Capable Forest Land <br /> <br />Most of the timber in the study area is mature <br />(conifer sawtimber and aspen poletimber). Other <br />stands with pole-size trees, seedlings/saplings, or <br />understocked areas are also present. Most of these <br />areas are probably the result of fires in the early <br />1900' s. Aspen, Engelmann spruce, ponderosa pine, <br />Douglas-fir and lodgepole pine are the predominant <br />forest types in the area. Bristlecone pine, limber <br />pine, pinon pine/juniper and several nopforest types <br />(alpine tundra, dwarf willows, montane meadow, <br />Gambel oak, Krummholz, and rock) are also present. <br /> <br />~ <br /> <br />Most of the study area has been logged or had some <br />timber cutting in the past. Most of this oCcurred <br />in conjunction with homesteading and provided house <br />logs, corral poles, and fence posts. Cutting for <br />mine props, railroad ties, bridge timbers, and <br />charcoal provided raw materials for mining and <br />commerce. Many of the steeper slopes were logged <br />with horses and the material removed on low-standard <br />wagon roads. <br /> <br />The WSA includes approximately 218,000 acres, of <br />which 25 percent is forest land as shown on Table E <br />capable of producing regulated timber products. <br />Approximately 49 percent of the suitable land base <br />is on slopes less than 45 percent and capable of <br />being logged wi th conventional harvesting systems. <br />See Figure 7. <br /> <br />44 <br /> <br />P02652 <br />
