Vegetation <br /> <br />The vegetation within the WSA will continue to be <br />influenced mainly by natural ecological forces under <br />the suitable alternative. Use of forage by <br />livestock will continue and potential mineral <br />activity may create site specific changes. <br />Restoration can return disturbed areas to production <br />but only over a long period of time because of the <br />slow recovery of fragile ecosystems. Aspen and <br />other temporary species would tend to be replaced by <br />climax species under the suitable alternative. <br /> <br />Under the suitable with modified boundary <br />alternative, the vegetation could be managed on up <br />to about 12 percent of the National Forest lands to <br />produce wood fiber, increase water yield, and <br />improve and maintain wildlife habitat. <br /> <br />Under the unsuitable alternative, the vegetation <br />could be managed on up to about 25 percent of the <br />National Forest lands to provide wood fiber, <br />increase water yield, and improve and maintain <br />wildlife habitat. <br /> <br />79 <br /> <br />(.,!t'\6~8 <br />.'4 ~ <br />
