The alpine-tundra lies above 11 , 800 feet elevation in <br /> the alpine zone. A variety of sites and microclimates produced <br /> by glaciation, wind , frost action, water and soil creep provide <br /> habitats ranging from cold wet bogs to shallow-soiled grasslands <br /> to relatively warm dry fellfields for a variety of plants such <br /> as willow, moss campion (Silene acaulis) , tufted hairgrass, <br /> bluegrass (Poa spp. ) , Kobresia (Kobresia bellardi) , buttercup <br /> (Ranunculus spp. ) , avens (Geum spp. ) and alpine thistle (Cirsium <br /> scopulorum) . Typically the plants are short, but range from <br /> less than one inch to more than two feet in height, and are <br /> mostly perennial . Glaciated cirques and talus slopes pervade <br /> the higher areas and are often colonized by lichen and <br /> cushion-like plants. <br /> Table 7 . 1-1 presents a partial list of plant species <br /> found in the subalpine and alpine zones around Climax, and Table <br /> 7 . 1-2 through 7 . 1-4 provides the major species, their life form <br /> and relative dominance within each of the forested communities. <br /> Table 7 . 1-1 . A partial list of the plants present in the sub- <br /> alpine and alpine-tundra areas in the vicinity of Climax. <br /> 7-2 <br />
