Large spots display bare mineral soil, interspersed with small clones of
Loiseleuria procumbens, scattered specimens of Arctostaphylos alpinus, Juncus trifidus, Carex bigelowii, Ranunculus glacialis (temporarily) and fragments of reindeer lichens (Cladina spp.).
Above 900 m in elevation, the grassland-forb-shrub formation is replaced by an alpine vegetation dominated by extensive heath mats of crowberry (Empetrum nigrum), alpine azalea (
Loiseleuria procumbens), diapensia (Diapensia lapponica), Kamchatka rhododendron (Rhododendron kamtschaticum), purple heather (Phyllodoce empetriformis), Alaska heather (Cassiope lycopodioides), alpine bearberry (Arctostaphylos alpina), mountain cranberry (Vaccinium vitis idea), bog blueberry (V.
Many Alpine clump-forming plants, such as the Alpine azalea (
Loiseleuria procumbens), spread their branches over the soil, forming dense carpets that bear the small flowering shoots and fruit.
