Name: Vaccinium uliginosum / Sibbaldiopsis tridentata Sparse Vegetation Reference: NatureServe Biotics 2019 Description: These sparsely vegetated rocky balds are found on subalpine and alpine summits of the northern Appalachian Mountains. They are on dry acidic rocky summits, ridges and outcrops composed of resistant granitic bedrock, mostly at elevations between 915 and 1525 m (3000-5000 feet), sometimes as low as 550 m (1800 feet). Soil development is minimal, with vascular vegetation confined to crevices. Expanses of bare rock with crustose lichens predominate. Vascular vegetation is usually less than 25% cover overall, although in patches coverage may approach 70%. The dominant plants are <i>Vaccinium uliginosum, Vaccinium vitis-idaea, Empetrum nigrum, Empetrum eamesii ssp. atropurpureum</i>, and <i>Sibbaldiopsis tridentata</i>. <i>Juncus trifidus</i> and, at higher elevations, <i>Carex bigelowii</i> may be present, but in far lower abundance than they are seen in alpine habitats. This association is related to the alpine ~<i>Vaccinium uliginosum - Rhododendron lapponicum / Juncus trifidus</i> Dwarf-shrubland (CEGL006298)$$, but occurs at lower elevations and lacks characteristic alpine plants such as <i>Diapensia lapponica, Agrostis mertensii, Rhododendron lapponicum</i>, etc. It differs from lower elevation open summits in the presence of subalpine <i>Vaccinium uliginosum</i> (and sometimes <i>Juncus trifidus</i> or <i>Carex bigelowii</i>).  Accession Code: urn:lsid:vegbank.org:commConcept:35162-{6C241D06-3948-43C8-9B53-B152BB286734} Plot-observations of this Community Concept: 0
