Name: Pinus strobus - Pinus banksiana - Quercus ellipsoidalis Forest & Woodland Macrogroup Reference: NatureServe Biotics 2019 Description: Stands of this Laurentian-Acadian macrogroup consist of a pine or oak overstory forming an open, patchy or continuous canopy with a variable understory. A combination of <i>Pinus strobus, Pinus banksiana, Pinus resinosa</i>, and (less commonly) <i>Picea mariana</i> are typical diagnostic overstory species. Common associates include the oaks <i>Quercus ellipsoidalis</i> and <i>Quercus rubra</i> along with a mix of other hardwoods, such as <i>Acer rubrum, Betula papyrifera, Populus grandidentata, Populus tremuloides, Thuja occidentalis</i>, and, less commonly, <i>Juniperus virginiana</i> which may dominate some examples on limestone habitats. The richness of the herbaceous layer is variable, but is typically moderately poor in closed-canopy stands and poor to rich in open stands. Stands may have a dominant cover of feathermosses and lichens. <i>Corylus cornuta</i> and <i>Corylus americana</i> are common tall shrubs; common low shrubs include <i>Vaccinium angustifolium</i> and <i>Vaccinium myrtilloides</i>. This macrogroup occurs from western Minnesota to the northern and western Great Lakes region, and into the northeastern United States, and possibly southeastern Canada. It occurs primarily on sandplains, outwash habitats, and coarse glacial deposits of sandy or loamy soils. Some examples occur on thin-soil limestone habitats such as bluffs adjacent to lakes, cliffs or talus and colluvial slopes. Fire is an important disturbance. Logging and forest management impact this macrogroup across its range.  Accession Code: urn:lsid:vegbank.org:commConcept:40527-{B713778E-10B5-4755-A77B-540EA9C27D35} Plot-observations of this Community Concept: 0
