In addition to soils, water availability may influence the distribution <br />and density of vegetation within this type. Most of the permit area is <br />located on very steep terrain and is shaded, even during the summer <br />months, for significant portions of the day. This may decrease <br />potential evaporation, providing relatively higher moisture <br />availability in certain locations, including allowing slow melting of <br />snow in the winter and spring. This many account for the pronounced <br />microgeographic variation in vegetation density observed on the site <br />and the high density of mountain mahogany and gambel oak in some <br />locations. <br />No consistent variations within this vegetation community were <br />observed which appeared to correlate with slope, aspect or elevation. <br />Past management does not appear to have affected this vegetation <br />community, at least for many years. No evidence of livestock <br />grazing or timber harvesting was observed on the site. <br />4. Field Data <br />Field data sheets for cover and production are attached. <br /> <br />
