Name: Picea mariana / Chamaedaphne calyculata / Sphagnum spp. Open Bog Woodland
Reference: Midwestern Ecology Working Group...
Description: This muskeg community is found in the sub-boreal regions of the Great Lakes in the United States and is widespread in Canada. Sites are on the crests of raised bogs in large peatland complexes, in basin bogs, and occasionally on shores isolated from groundwater influence. Vegetation structure is complex with a dominant layer of dwarf-shrubs, stunted trees and hummock-hollow microtopography. Ericaceous dwarf-shrubs dominate the stand, with over 40% cover. Dominant species include <i>Andromeda polifolia var. glaucophylla, Chamaedaphne calyculata, Kalmia polifolia</i>, and <i>Ledum groenlandicum</i>. Creeping dwarf-shrubs include <i>Gaultheria hispidula</i> and <i>Vaccinium oxycoccos</i>. Trees average about 10-25% cover, may be stunted (3 m tall) and are often clumped on higher hummocks with intervening, weakly-developed hollows. Typical species include <i>Picea mariana</i> and <i>Larix laricina</i>. The herbaceous layer contains graminoids such as <i>Carex oligosperma, Carex pauciflora</i>, and <i>Eriophorum vaginatum</i>, and forbs such as <i>Maianthemum stellatum</i> and <i>Sarracenia purpurea</i>. The nonvascular layer contains a carpet of <i>Sphagnum</i> (including <i>Sphagnum fuscum</i> and <i>Sphagnum magellanicum</i>), with patches of <i>Pleurozium schreberi</i>.
