Name: Lupinus arcticus Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance typically occurs at or slightly below the upper treeline in high Cascades of the Pacific Northwest, often in association with subalpine parkland. Deep snow accumulations and elevations between 1800-2000 m create a short growing season. These communities occur on well-drained, moderately steep to steep slopes, which clear of snow by early summer. These are lush herbaceous communities with a mixture of forbs and graminoids. Lupinus arcticus ssp. subalpinus is the dominant species, but Carex spectabilis may be codominant in some stands. Other forbs with high constancy include Polygonum bistortoides, Castilleja parviflora, Potentilla flabellifolia, Pulsatilla occidentalis (= Anemone occidentalis), Valeriana sitchensis, and Erigeron peregrinus. Carex nigricans and Festuca idahoensis are occasional graminoids present.  Accession Code: VB.CC.22213.LUPINUSARCTICUS Plot-observations of this Community Concept: 0
