A1116 Vaccinium uliginosum - Mixed Alpine Heath Alliance

Type Concept Sentence: This alliance includes alpine dwarf-shrublands of the Northern Appalachian and eastern alpine regions on the Canadian Shield, generally characterized by Vaccinium uliginosum, often mixed with other dwarf-shrubs.


Common (Translated Scientific) Name: Bog Blueberry - Mixed Alpine Heath Alliance

Colloquial Name: Bog Blueberry - Mixed Alpine Heath

Hierarchy Level:  Alliance

Type Concept: This alliance includes alpine dwarf-shrublands generally characterized by Vaccinium uliginosum, often mixed with other dwarf-shrubs and lesser amounts of graminoids and forbs. Other species associated with this alliance include Betula glandulosa, Empetrum nigrum, Ledum groenlandicum, Rhododendron lapponicum, Salix uva-ursi, Vaccinium vitis-idaea, and the herbs Carex bigelowii, Cornus canadensis, Juncus trifidus, Minuartia groenlandica, Sibbaldiopsis tridentata, and Solidago multiradiata. These communities are restricted to alpine areas in the Northern Appalachian and eastern alpine regions on the Canadian Shield. Typically they occur above timberline on exposed, windswept mountain summits, ridges, and bedrock-dominated tablelands.

Diagnostic Characteristics: Alpine dwarf-shrublands generally characterized by Vaccinium uliginosum, often mixed with other dwarf-shrubs, including Betula glandulosa, Empetrum nigrum, Ledum groenlandicum, Rhododendron lapponicum, Salix uva-ursi, Vaccinium vitis-idaea, and the herbs Carex bigelowii, Cornus canadensis, Juncus trifidus, Minuartia groenlandica, Sibbaldiopsis tridentata, and Solidago multiradiata.

Classification Comments: Jones et al. (2012) also describe a "Heath-shrub-rush" community that is a catch-all type for exposed and windswept plant communities that don''t fit the Diapensia or cushion-tussock type, including species such as Luzula spp., Vaccinium vitis-idaea, Ledum groenlandicum, Empetrum nigrum, and Arctostaphylos alpina. That type appears to fit well with this alliance. Other authors refer to this type as "alpine ridge community" or "alpine shrublands."

Physiognomy and Structure: This alliance is characterized by a dominance of dwarf-shrubs. There is a varying amount of exposed or lichen-covered rock.

Floristics: The dominant dwarf-shrub is Vaccinium uliginosum, often in associated with others such as Ledum groenlandicum, Betula glandulosa, Empetrum nigrum, Rhododendron lapponicum, Salix uva-ursi, and the herbs Juncus trifidus, Carex bigelowii, Sibbaldiopsis tridentata (= Potentilla tridentata), and Minuartia groenlandica.

Dynamics:  This alliance is exposed to high winds and low temperatures; frost-heaving of the substrate often occurs.

Environmental Description:  This alliance includes alpine dwarf-shrublands that typically occur above timberline on exposed, windswept mountain summits, ridges, and bedrock-dominated tablelands. Soils are acidic, well-drained gravel and sand with a shallow organic layer.

Geographic Range: These communities are restricted to alpine areas in the Northern Appalachian and eastern alpine regions on the Canadian Shield.
