Name: Betula nana - Salix pulchra Mesic Low Shrubland Group
Reference: NatureServe Biotics 2019
Description: This shrubland group occurs on mesic, mid- to upper-slope sites throughout the boreal and subboreal regions of Alaska and is often matrix-forming above coniferous treeline. <i>Betula glandulosa</i> dominates in the boreal with dominance transitioning to <i>Betula nana</i> in the subboreal region of southwest Alaska. <i>Vaccinium uliginosum</i> and <i>Ledum palustre ssp. decumbens</i> both have high constancy and canopy cover and may occasionally be canopy dominants. Other common shrubs include <i>Salix pulchra</i> and <i>Salix glauca</i>. Dwarf-shrubs, including <i>Vaccinium vitis-idaea</i> and <i>Empetrum nigrum</i>, may be common below the low-shrub layer. Herbaceous species are sparse and may include <i>Calamagrostis canadensis, Carex bigelowii, Rubus chamaemorus</i>, and <i>Chamerion angustifolium ssp. angustifolium</i>. Feathermosses such as <i>Hylocomium splendens</i> and <i>Pleurozium schreberi</i>, lichens in the genus <i>Cladonia</i>, and <i>Sphagnum</i> species are common in the ground layer. Wetland sites with organic soils are not included in this group.
