Name: Arctic Dwarf Birch Low Shrub Tundra Alliance
Reference: NatureServe Biotics 2019
Description: This alliance is dominated by <i>Betula nana</i> and is commonly found throughout the low arctic region on mesic to moist sideslopes and ridges in the Brooks Range foothills and on high-centered polygonal tundra of the Arctic Coastal Plain. Vegetation is characterized by low and prostrate shrubs, including <i>Betula nana, Ledum palustre ssp. decumbens, Vaccinium uliginosum</i>, and <i>Salix pulchra</i>. Dwarf-shrubs such as <i>Vaccinium vitis-idaea</i> and <i>Loiseleuria procumbens</i> may be common. Herbaceous species are sparse, but certain graminoids have high constancy, including <i>Anthoxanthum monticola ssp. alpinum</i> in montane sites and sedges in moist tundra on the coastal plain. Fruticose lichens, particularly <i>Cladonia rangiferina</i> and other <i>Cladonia</i> species, are often abundant in the ground layer. Common mosses include <i>Hylocomium splendens</i> and <i>Sphagnum, Aulacomnium</i>, and <i>Polytrichum</i> species. Patch size is small to matrix-forming.
