<br />OO?~58 <br /> <br />ranoval and alteration in mountainous terrain is the increased <br />potential for erosion. <br /> <br />Vegetation management along the cleared areas will need to <br />consider sunscald in aspen and windfall risk in all species. <br /> <br />Opportunities for vegetation management will be available to <br />enhance the visual resource and wildlife habitats in the timbered <br />areas between ski runs. Aspen will be the primary species to work <br />with. Vegetation nanagement prescriptions that take into account <br />timber, insect and disease, wildlife needs, soils, and aesthetic <br />values would be employed. <br /> <br />2. Wildlife Habitat <br /> <br />Wildlife habitats are as defined in Managing Forested Lands For <br />Wildlife m.L. Hoover and D. L. Wills Editors, Published by Colorado <br />Division of Wildlife, 1984). The effects discussed will relate to: a) <br />vegetative type conversion, b) change in the size class of timbered <br />types, c) change in the percent of canopy closure in timberro types. <br />The effects of the proposed ski area plus the associated private land <br />impacts on wildlife habitat are displayed in Table IV-17. This table <br />shows acres by vegetative type, by structural stage and by canopy <br />closure class. The approximated acres are shown at the current <br />situation and for each of the three alternatives. <br /> <br />TABLE IV-17 <br /> <br />Acres After Implementation of Each Alternative <br />C~red to the Existing Situation <br /> <br /> Existing Alternative Alternative Alternative <br />Vegetation/Tvoe Situation Qne.
