This jack pine woodland community type is found in upper midwestern United States and possibly adjacent Canada. Stands are found on flat to rolling topography, such as glaciofluvial and lacustrine deposits, moraines, and other glacial features. The soils are sandy loams, fine sands, and loamy sands, shallow to deep, and with low organic content. The overstory of this forest community is dominated by moderately to densely spaced conifers with a scattering of deciduous trees. The trees in this community are typically 15-20 m tall. <i>Pinus </i><i>banksiana</i> is often the sole dominant. <i>Pinus resinosa, Betula papyrifera</i>, and <i>Populus tremuloides</i> are canopy associates, and the subcanopy is typically sparse. The shrub layer contains abundant <i>Corylus cornuta</i>, along with <i>Amelanchier</i> spp., <i>Corylus americana, Diervilla lonicera, Vaccinium angustifolium</i>, and <i>Viburnum rafinesquianum</i>. The herb layer is often dominated by <i>Pteridium aquilinum</i>, with common species including <i>Linnaea borealis, Gaultheria procumbens</i>, and <i>Chimaphila umbellata</i>. |

This white pine forest type is found in the hemi-boreal region of the midwestern United States and in adjacent parts of Canada. Stands occur on moderately deep to deep (>60 cm) sandy or gravelly loam soil. The canopy is dominated by <i>Pinus strobus</i>, often mixed with <i>Pinus resinosa</i>. The lower layer of the canopy consists mainly of <i>Abies balsamea</i> trees and saplings. Other trees that may be found in this layer include <i>Acer rubrum, Betula papyrifera, Betula alleghaniensis, Picea glauca</i>, and <i>Thuja occidentalis</i>. The tall-shrub/sapling layer is moderate to well-developed and consists of <i>Abies balsamea, Acer spicatum, Corylus cornuta</i>, and, less frequently, <i>Amelanchier</i> spp. The low-shrub layer is not well-developed and is dominated by <i>Diervilla lonicera, Linnaea borealis, Vaccinium myrtilloides</i> and <i>Vaccinium angustifolium</i>. The herb stratum is often sparse. Prevalent herbs include <i>Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Cornus canadensis, Maianthemum canadense, Polypodium virginianum (= Polypodium vulgare)</i>, and <i>Pteridium aquilinum</i>. Moss species include <i>Dicranum polysetum</i> and <i>Pleurozium schreberi</i>. The forest floor is generally characterized by a deep layer of pine needle litter. Diagnostic features include dominance by <i>Pinus strobus</i>, a well-developed tall-shrub layer with <i>Acer spicatum</i> and <i>Corylus cornuta</i>, and a sparse herb layer. |
