CEGL002480 Pinus strobus - (Pinus resinosa) - Quercus rubra Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Eastern White Pine - (Red Pine) - Northern Red Oak Forest

Colloquial Name: White Pine - Red Oak Forest

Hierarchy Level:  Association

Type Concept: This white pine - oak forest occurs in the central Great Lakes region of the United States and Canada, where it occurs on dry to dry-mesic sites with well-drained sandy loams or coarser soils, typically on morainal slopes or outwash plains. Pinus strobus is the dominant component of the overstory, often forming a supercanopy above the hardwood canopy. Quercus rubra is an important canopy species, along with Acer saccharum, and Quercus alba in central Minnesota, and, farther eastward, Fraxinus americana, Quercus velutina, and occasional Fagus grandifolia. Northern stands may contain Acer rubrum, Betula papyrifera, Pinus resinosa, Pinus strobus, Populus grandidentata, and Populus tremuloides, along with Abies balsamea in the understory. Disturbed stands may be more strongly dominated by Pinus strobus, Populus tremuloides, and Acer rubrum. The shrub and vine layer in the southern part of the range contains Cornus foemina, Corylus americana, Parthenocissus quinquefolia, and Vaccinium angustifolium, and, farther north, Corylus cornuta, Diervilla lonicera, Gaultheria procumbens, Vaccinium angustifolium, Vaccinium myrtilloides, and Viburnum acerifolium. Typical herbs in the southern part of the range include Amphicarpaea bracteata, Aralia nudicaulis, Carex pensylvanica, and Geranium maculatum; farther north, they include Eurybia macrophylla, Maianthemum canadense, Oryzopsis asperifolia, Polygala paucifolia, Polygonatum pubescens, Pteridium aquilinum, and Trientalis borealis. Mosses include Ptilidium pulcherrimum.

Classification Comments: Distinction between this type and ~Pinus strobus - Quercus alba / (Corylus americana, Gaylussacia baccata) Forest (CEGL002481)$$, which is found on sands, needs clarification. Compare also with ~Pinus strobus - Quercus (rubra, velutina) - Fagus grandifolia Forest (CEGL006293)$$ in the East. Type may have a boreal variant [see Voyageurs National Park and descriptions from central Ontario (Chambers et al. 1997)]. If Minnesota White Pine-Hardwood Forest (especially north-central subtype) is primarily a sandplain type, all of it should be placed with CEGL002481. In Wisconsin, this type grades into the pure evergreen white pine type, ~Pinus strobus / Acer spicatum - Corylus cornuta Forest (CEGL002445)$$.

Floristics: Pinus strobus is the dominant component of the overstory, often forming a supercanopy above the hardwood canopy. Quercus rubra is an important canopy species, along with Acer saccharum and Quercus alba in central Minnesota, and, farther eastward, Fraxinus americana, Quercus velutina, and occasional Fagus grandifolia. Northern stands may contain Acer rubrum, Betula papyrifera, Pinus resinosa, Pinus strobus, Populus grandidentata, and Populus tremuloides, along with Abies balsamea in the understory.

Typical herbs in the southern part of the range include Amphicarpaea bracteata, Aralia nudicaulis, Carex pensylvanica, and Geranium maculatum; farther north, they include Eurybia macrophylla (= Aster macrophyllus), Maianthemum canadense, Oryzopsis asperifolia, Polygala paucifolia, Polygonatum pubescens, Pteridium aquilinum, and Trientalis borealis. Mosses include Ptilidium pulcherrimum, among others (Eyre 1980, MNNHP 1993, Chambers et al. 1997).

Dynamics:  This type can be simplified floristically and structurally by severe disturbance factors. Natural disturbances, such as large windthrow events followed by fire, can cause stands to be dominated by Pinus strobus and Populus tremuloides, with a strong Pteridium aquilinum understory. Anthropogenic disturbance factors include logging and severe fire. In addition, areas planted to pine (but not in rows) by the Civilian Conservation Corps in the 1930s may also resemble these early-seral stages.

Environmental Description:  Sites are found on dry-mesic to mesic sites with well-drained sandy loams or coarser soils, typically on morainal slopes and ridges, or on outwash plains.

Geographic Range: This white pine - oak forest community occurs in the central Great Lakes region of the United States and Canada, where it occurs on dry to dry-mesic sites. Stands range from east-central Minnesota east to Michigan and Ontario.
