NatureServe Biotics 2019
Description:
This type includes both forested bogs and acidic swamps. In forested bogs <i>Picea mariana</i> is the dominant overstory species, generally growing with a stunted growth form in a sparse to open canopy (10-30% canopy cover). Common understory species include <i>Ledum palustre ssp. decumbens, Ledum groenlandicum, Andromeda polifolia, Betula nana, Empetrum nigrum, Vaccinium vitis-idaea, Vaccinium uliginosum, Chamaedaphne calyculata, Rubus chamaemorus, Carex pluriflora, Carex</i> spp., and <i>Eriophorum angustifolium</i>. <i>Sphagnum</i> spp. dominate the bryophyte layer. Well-developed bogs may have a significant lichen component in the ground layer composed largely of <i>Cladina</i> spp. and <i>Cladonia</i> spp. In acidic swamps, <i>Picea mariana</i> is the dominant overstory species in an open canopy (30-50% canopy cover). Other overstory associates may include <i>Larix laricina, Picea glauca</i> or, in the subboreal Rocky Mountain region, <i>Picea glauca x engelmannii</i> (hybrid white spruce). Shrubs may include <i>Alnus incana ssp. tenuifolia, Betula nana</i> and <i>Ledum groenlandicum</i>. Characteristic herbaceous species include <i>Carex aquatilis, Equisetum</i> spp., and <i>Petasites frigidus</i>. Moss cover is high; typical species include <i>Aulacomnium palustre, Tomentypnum nitens, Pleurozium schreberi, Sphagnum</i> spp., and <i>Hylocomium splendens</i>, among others.
