Name: Chamaedaphne calyculata / Carex oligosperma / Sphagnum spp. Poor Fen Dwarf-shrubland Reference: Midwestern Ecology Working Group... Description: This dwarf-shrub poor fen community is found in the northern Great Lakes region and across much of central Canada. Sites are found on peatlands with low exposure to mineral-rich groundwater, including basin fens, shores above the level of seasonal flooding, and margins of larger peatlands. Stands have a saturated hydrology with a fibric Sphagnum spp. peat soil and a pH usually <4.5. Vegetation is dominated by an open dwarf-shrub/scrub conifer layer with very scattered trees (<10% cover). Microtopography is high to intermediate hummocks with hollows or a flat lawn of Sphagnum spp. Ericaceous dwarf-shrubs are dominant, including Chamaedaphne calyculata, Kalmia polifolia, and Ledum groenlandicum, and the creeping dwarf-shrubs Andromeda polifolia and Vaccinium oxycoccos. Betula pumila has low cover but is fairly constant. Scrub conifers include Larix laricina and Picea mariana. They also occur as scattered trees (>3 m). The herb layer is species-poor, containing Carex oligosperma, Carex limosa, Equisetum fluviatile, Menyanthes trifoliata, Sarracenia purpurea, and Scheuchzeria palustris. The moss layer forms a continuous hummocky mat dominated by Sphagnum angustifolium, Sphagnum fuscum, and Sphagnum magellanicum. Diagnostic features include the dominance of a dwarf-shrub ericaceous layer, absence of a tree layer (<10%), species-poor herbaceous layer, and a low abundance of minerotrophic indicators, such as Betula pumila, Carex aquatilis and Carex stricta.  Accession Code: VB.CC.26174.CHAMAEDAPHNECAL Plot-observations of this Community Concept: 0
