Name: Picea mariana Ontario-Québec Boreal Poor Swamp Group
Reference: NatureServe Biotics 2019
Description: This is a poor acidic forested peatland (poor to intermediate swamp) found across the eastern boreal and subboreal regions of Canada, extending southward to the northern Great Lakes region and parts of the northeastern United States. The group is primarily moderately to weakly minerotrophic (similar to poor fen), and even approaching ombrotrophic (bog) conditions. They are typically found in poorly drained basins or kettleholes, with level, wet, poorly drained organic soils, and a shallow to thick layer of peat that reduces contact with groundwater. Trees form a partial to full cover over most or all of the peatland. Stunted to well-developed <i>Picea mariana</i> is the dominant canopy species. Other common trees include <i>Larix laricina, Abies balsamea</i>, and <i>Pinus banksiana</i>. Heaths and sedges are common in the understory. A sparse to moderately well-developed low-shrub layer contains mostly ericaceous species such as <i>Chamaedaphne calyculata, Ledum groenlandicum, Gaultheria hispidula, Vaccinium</i> spp., and <i>Kalmia</i> spp. Mosses commonly include <i>Sphagnum</i> spp., <i>Pleurozium schreberi</i>, and <i>Dicranum polysetum</i>.
