This community is found in the northern Great Lakes and Northern Appalachian/Boreal region of the United States and Canada and elsewhere in the boreal regions of central and eastern Canada. Sites are found on level, wet sites with organic soils, but not generally as components of large open peatlands. These sites are poorly drained and acidic, allowing a moderate to thick layer of peat to accumulate. Nutrient levels are very low. The overstory of this community is dominated by conifers. The tree canopy is closed to broken to closed with a moderately well-developed low-shrub layer, sparse herbaceous layer, and a carpet of mosses. The canopy is often pure <i>Picea mariana</i>. The only other trees that are occasionally found with it are <i>Abies balsamea, Larix laricina</i>, and <i>Pinus banksiana</i>. The shrubs are primarily ericaceous and include <i>Chamaedaphne calyculata, Gaultheria hispidula, Kalmia polifolia, Ledum groenlandicum</i>, and <i>Vaccinium myrtilloides</i>, as well as <i>Cornus canadensis</i>. In the Northeast, shrubs may include <i>Kalmia angustifolia, Nemopanthus mucronatus, Viburnum nudum var. cassinoides</i>, or <i>Rhododendron canadense</i>. The few herbaceous species that live in this community include <i>Carex trisperma, Eriophorum vaginatum var. spissum, Clintonia borealis</i>, and <i>Maianthemum trifolium (= Smilacina trifolia)</i>. <i>Sphagnum</i> spp., <i>Dicranum polysetum</i>, and <i>Pleurozium schreberi</i> are the major species constituting the abundant moss layer. |

This oak - (pine) rocky woodland community is found in restricted areas of the hemi-boreal regions of the Lake States in the United States and in adjacent Canada. Stands occur on warm, rocky outcrops and well-drained sandy sites. Soils are shallow, dry to fresh, and rapidly drained. The tree canopy is scattered and often stunted. This type is characterized by either a canopy dominated by <i>Quercus ellipsoidalis</i>, with occasional <i>Quercus macrocarpa</i> or <i>Pinus banksiana</i>, or with large <i>Pinus banksiana, Pinus resinosa</i>, or <i>Pinus strobus</i> either forming an emergent canopy over the oak trees, or mixed with the oaks. These evergreen trees may have 25-75% cover; thus this type varies from pure deciduous to mixed evergreen-deciduous, and from 30% cover (woodland physiognomy) to 90% cover (forest physiognomy). <i>Corylus cornuta, Viburnum rafinesquianum, Quercus ellipsoidalis</i>, and <i>Amelanchier</i> spp. are the most abundant species in the shrub layers and usually cover 20-40% of the forest floor. <i>Vaccinium angustifolium</i> is the most common dwarf-shrub and is present at low (<25%) cover. In stands with much exposed bedrock, the dwarf-shrubs <i>Juniperus communis, Prunus pumila, Arctostaphylos uva-ursi</i>, and <i>Comptonia peregrina</i> may also be present. Cover of the herbaceous layer is highly variable, ranging from 20-80%, with the most abundant herbs being <i>Pteridium aquilinum, Eurybia macrophylla (= Aster macrophyllus)</i>, and <i>Aralia nudicaulis</i>. Species typical of bedrock outcrops and shallow soils can also be found and include <i>Danthonia spicata, Poa alsodes, Elymus trachycaulus (= Agropyron trachycaulum), Maianthemum canadense, Schizachne purpurascens</i>, and <i>Oryzopsis asperifolia</i>. The nonvascular layer can be absent or present with up to 30% cover. In the open bedrock areas this layer consists mainly of the lichens <i>Cladina rangiferina, Cladina mitis</i>, and <i>Cladina stellaris</i> and, to a lesser degree, the mosses <i>Polytrichum juniperinum, Polytrichum piliferum, Hedwigia ciliata</i>, and <i>Orthotrichum</i> spp. Under the canopy of oaks, the nonvascular strata consists primarily of <i>Pleurozium schreberi</i> and <i>Dicranum</i> spp. Diagnostic features of the type include the forest or woodland canopy consisting primarily of <i>Quercus ellipsoidalis</i>, with varying amounts of <i>Quercus macrocarpa, Pinus banksiana, Pinus resinosa</i> and <i>Pinus strobus</i>, and a rocky substrate, with dry herbaceous, moss, and lichen species. |
