Name: Chamaedaphne calyculata - Ledum groenlandicum - Kalmia polifolia Bog
Reference: NatureServe Biotics 2019
Description: This dwarf-shrub bog community is found in the northern Great Lakes region and across much of central Canada. Sites are found on raised bog landforms in large peatland complexes, basin bogs, and occasionally on shores (but still isolated from groundwater influence). Stands have a saturated hydrology with a fibric <i>Sphagnum</i> spp. peat soil and a pH usually &lt;4.3. Vegetation is dominated by an open dwarf-shrub/scrub conifer layer with very scattered trees (&lt;10% cover). Microtopography is high hummocks with weakly developed hollows. Ericaceous dwarf-shrubs are dominant, including <i>Chamaedaphne calyculata, Kalmia polifolia</i>, and <i>Ledum groenlandicum</i>, and the creeping dwarf-shrubs <i>Andromeda polifolia</i> and <i>Vaccinium oxycoccos</i>. Scrub conifers include <i>Larix laricina</i> and <i>Picea mariana</i>. They also occur as scattered trees (&gt;3m). The herb layer is species poor, containing <i>Carex oligosperma, Carex pauciflora, Eriophorum vaginatum</i>, and <i>Sarracenia purpurea</i>. The moss layer forms a continuous hummocky mat dominated by <i>Sphagnum angustifolium, Sphagnum fuscum</i>, and <i>Sphagnum magellanicum</i>. Diagnostic features include the dominance of a dwarf-shrub ericaceous layer, absence of a tree layer (&lt;10%), species-poor herbaceous layer, and almost complete lack of minerotrophic indicators, such as <i>Betula pumila, Carex aquatilis</i>, and <i>Carex stricta</i>. A possible subtype may occur in which pools form near the bogs crests, and contain maritime species such as <i>Scheuchzeria palustris, Rhynchospora alba, Sphagnum cuspidatum</i>, and <i>Utricularia cornuta</i>.
