Name: Arctic Acidic Dwarf Willow Tundra Alliance
Reference: NatureServe Biotics 2019
Description: This tundra alliance is dominated by dwarf willow shrubs and is commonly found on exposed sites in the arctic and subarctic regions of Alaska and Canada. The alliance is indicated by the dwarf willows <i>Salix reticulata, Salix polaris, Salix rotundifolia</i>, and <i>Salix phlebophylla</i>. Characteristic species include the dwarf-shrubs <i>Dryas octopetala</i> and <i>Cassiope tetragona</i>, the graminoids <i>Carex bigelowii</i> and <i>Arctagrostis latifolia</i>, the forb <i>Petasites frigidus</i>, and the lichens <i>Flavocetraria cucullata</i> and <i>Thamnolia vermicularis</i>. The erect shrub <i>Salix pulchra</i> is constant at low cover. This is a small-patch type developing in shallow, well-drained soils on non-acidic substrates underlain by permafrost.
