Name:
Pinus banksiana - Pinus resinosa - Picea mariana Subboreal Forest Group
Reference:
NatureServe Biotics 2019
Description:
This subboreal forest group is found on dry-mesic nutrient-poor soils in a variety of topographic settings. It ranges from northwestern Ontario to eastern Canada, and southward into Minnesota, the Great Lakes region, and very locally into northwestern Maine. Soils are loamy to sandy, varying from nutrient-poor, thin soils over bedrock to deeper soils, sometimes sandy. Sites are typically dry-mesic. The dominant fire regime varies from 50-100 years. <i>Pinus banksiana, Pinus resinosa</i>, and <i>Picea mariana</i> are characteristic overstory species, with <i>Pinus strobus</i> occasionally common, over much of the range, but east of the Great Lakes, <i>Picea mariana</i> becomes increasingly dominant with <i>Abies balsamea</i> as an important associate. 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. Subboreal indicators need to be described.
