Name:
Picea mariana / Ledum groenlandicum / Eriophorum brachyantherum Boreal Bog & Acidic Fen Group
Reference:
NatureServe Biotics 2019
Description:
This group extends across the western boreal regions of North America, extending south into subboreal regions of the Pacific Maritime and Rocky Mountain divisions. It occurs in wet depressions and old lake basins. Occurrences form where the rate of peat accumulation exceeds its decomposition, resulting in ombrotrophic and acidic peatlands in which the bog surface is raised above the water table. Patch size is small to large. These are primarily depressional wetlands, and secondary bog pools may also be present. This group may be tree- or shrub-dominated or dwarf-shrub/herbaceous. Trees may be stunted and dwarfed. Trees are dense or scattered, with common species including <i>Picea mariana, Picea glauca</i>, and <i>Larix laricina</i>. Dominant shrubs include <i>Betula nana, Ledum palustre ssp. decumbens, Ledum groenlandicum, Andromeda polifolia, Kalmia polifolia, Chamaedaphne calyculata, Empetrum nigrum, Rubus chamaemorus, Vaccinium oxycoccos, Vaccinium vitis-idaea</i>, and <i>Vaccinium uliginosum</i>. The herbaceous layer is typically graminoid-dominated. Species include <i>Carex chordorrhiza, Carex lasiocarpa, Carex limosa, Carex livida, Carex membranacea, Carex microglochin, Carex pauciflora, Carex pluriflora, Carex rariflora</i> (more eastern), <i>Carex rotundata</i> (more eastern), <i>Carex stylosa, Eriophorum brachyantherum</i>, and <i>Eriophorum angustifolium</i>.
