Name: Picea mariana - Pinus banksiana Ontario-Québec Boreal Mesic-Moist Forest Group
Reference: NatureServe Biotics 2019
Description: This conifer forest group is found on nutrient-poor soils in a variety of topographic settings. It ranges from northwestern Ontario to Newfoundland and Labrador. Soils are loamy to sandy, varying from nutrient-poor, thin soil over bedrock to deeper soils, sometimes sandy. Sites are typically dry-mesic. The dominant fire regime varies from 50-100 years. <i>Picea mariana</i> and <i>Pinus banksiana</i> are characteristic overstory species over much of the range. Canopy structure is mostly closed but can be partially open. Conifers typically dominate the canopy, but boreal hardwoods (<i>Populus tremuloides, Betula papyrifera</i>) may codominate. As time since fire increases, <i>Picea mariana</i> may dominate. Tree regeneration includes <i>Abies balsamea, Betula papyrifera, Populus tremuloides</i>, and <i>Picea mariana</i>. The shrub and field layers can be very open to somewhat dense (5-75% cover). Characteristic low-shrub and herb species include <i>Amelanchier</i> spp., <i>Vaccinium angustifolium, Diervilla lonicera, Cornus canadensis, Linnaea borealis, Doellingeria umbellata</i>, and <i>Eurybia macrophylla</i>. Older <i>Picea mariana</i> stands may be strongly dominated by feathermosses.
