Name:
Empetrum nigrum - Phyllodoce aleutica Aleutian Dwarf-shrubland Group
Reference:
NatureServe Biotics 2019
Description:
This group is common on cliffs, rocky outcrops, exposed summits, windswept ridges, fell-fields, valley bottoms, sideslopes, stabilized dunes, terraces, moraines and fans of the Alaska Peninsula, Aleutian Islands and Kodiak Island. Slopes vary from flat to steep. Patch size is small to matrix-forming. The continuous dwarf-shrub heaths often fragment into strips that alternate with almost bare ground, possibly due to wind erosion and frost action. Total vascular plant cover varies from sparse to open and is typically dwarf-shrub-dominated, but herbaceous cover may range up to 75%. Various dwarf-shrub species dominate or codominate, including <i>Arctostaphylos alpina, Cassiope lycopodioides, Empetrum nigrum, Harrimanella stelleriana, Loiseleuria procumbens, Phyllodoce aleutica, Salix arctica, Salix rotundifolia, Vaccinium uliginosum</i>, and <i>Vaccinium vitis-idaea</i>. Common herbaceous species include <i>Agrostis mertensii, Carex circinata, Carex macrochaeta, Chamerion angustifolium, Deschampsia cespitosa, Festuca rubra, Geum calthifolium, Leymus mollis, Lupinus nootkatensis, Polygonum viviparum, Potentilla villosa, Saxifraga bronchialis, Saxifraga oppositifolia</i>, and <i>Veronica wormskjoldii var. stelleri</i>. Bryophyte cover is often high.
