<br />A. Grasslands and Meadows of Alpine Regions Above Timberline <br />(BLUE) <br /> <br />The alpine areas with adequate vegetal cover are suitable for <br />seasonal grazing by wildlife and domestic 1 ivestock. Water <br />yield from the snowpack is important for this area. Recre- <br />ation (backpacking, skiing, etc.) is also an important use. <br /> <br />I <br />i ~ <br />t <br />I . <br />i <br />; I <br /> <br />The alpine plant association occurs above the timberl ine at <br />elevations about 11,500 feet C3,505 m). The growing season at <br />this elevation is short and the cl imate, even in sunmer, is <br />severe. Vegetative production is meager and the plant com- <br />munities are fragile, exhibiting extremely slow recuperation <br />rates following disturbance. The species usually found in the <br />alpine meadow are sedges, tufted hairgrass, b1uegrasses, spike <br />trisetum, alpine timothy, willows, bistort, bluebells, gentian, <br />clovers, and kobresia. <br /> <br />Alpine barren areas include those alpine areas on which there <br />is no natural vegetation, or practically none including shale, <br />rock slides. snow fields, and glaciers. <br /> <br />I <br />! <br />i <br />I <br />! <br />! <br />! <br />I <br />! . <br />! <br />l <br />I <br /> <br /> <br />Grassland and Meadows of Alpine Regions <br />above Timberl ine. <br /> <br />r ,~ <br />;~, '+ <br /> <br />'.0 <br />...; <br /> <br />B-2 <br /> <br />";~ <br />
