| | ROCKY MOUNTAIN ALPINE |
 | | Like the arctic tundra, it is characterized by the absence of trees, the short stature of plants, and a low annual mean temperature. |
 | | The area is floristically diverse with over 422 species of alpine plants which has been attributed to the 1) expansiveness, 2) east-west orientation with many moist N-facing slopes, 3) dissection of north-south migration routes, 4) high elevations which escaped glaciation, 5) variety of soil types, and 6) the relative accessibility. |
 | | Alpine ectomycorrhizal fungi are primarily agarics (gilled mushrooms) mutualistic with alpine plants such as dwarf willow (Salix reticulata, Salix arctica), shrubby willow (Salix planifolia, Salix glauca), bogbirch (Betula gladulosa), and the mat plant Dryas octopetala, although other plants are implicated. |
