Name: Picea mariana - Abies balsamea / Sibbaldiopsis tridentata Shrubland Reference: NatureServe Biotics 2019 Description: This shrubby alpine krummholz occurs at high elevations in the Northern Appalachians of the northeastern United States and adjacent Canada. The setting is high, wind-exposed alpine peaks and exposed high-elevation summits, usually from 1067-1494 m (3500-4900 feet) elevation. Soils are thin organic Histosols or peat. The stunted trees form matted, wind-pruned alpine conifer thickets, usually of 60-100% cover. Dwarf-shrubs and herbs are occasional in openings among the shrubby trees. Bryoids, also in the openings, are sparse; decomposing organic litter makes up the remainder of the ground cover. The krummholz is dominated by a variable mixture of <i>Picea mariana, Abies balsamea</i>, and <i>Betula papyrifera var. cordifolia</i>. Dwarf-shrubs and herbs include <i>Ledum groenlandicum, Vaccinium uliginosum, Empetrum nigrum, Vaccinium vitis-idaea, Clintonia borealis, Cornus canadensis, Sibbaldiopsis tridentata, Trientalis borealis, Gaultheria hispidula</i>, and <i>Solidago macrophylla</i>. This association shares many species with subalpine spruce-fir forests (e.g., ~<i>Abies balsamea - (Betula papyrifera var. cordifolia)</i> Forest (CEGL006112)$$), but the low stature and matted form of the trees is distinctive.  Accession Code: urn:lsid:vegbank.org:commConcept:34688-{2EC73339-4282-43D1-88FF-6AB41A0978DE} Plot-observations of this Community Concept: 0
