This hemi-boreal upland white-cedar forest occurs in the United States in northeastern Minnesota and in the eastern boreal regions of Canada. Stands are found on gentle moist slopes to very steep well-drained slopes. Soils are fine to moderately coarse-textured, usually calcareous, moderately deep to deep (50-100 cm), and often contain boulders at the surface. The overstory is dominated by coniferous trees, with or without a substantial deciduous component. <i>Thuja occidentalis</i> is the most abundant tree and may occur in pure stands. Other canopy species include <i>Abies balsamea, Acer rubrum, Betula papyrifera, Picea glauca, Picea mariana, Populus tremuloides</i>, and <i>Pinus strobus</i>. There is usually an abundant shrub/sapling layer with saplings of <i>Thuja occidentalis</i> and <i>Abies balsamea</i> along with <i>Acer pensylvanicum</i> and the shrubs <i>Acer spicatum, Corylus cornuta, Linnaea borealis, Lonicera canadensis, Rubus pubescens</i>, and <i>Sorbus decora</i>. <i>Vaccinium angustifolium</i> and <i>Viburnum nudum var. cassinoides</i> may be present on more acidic sites. The ground layer is typically diverse on mesic to wet-mesic stands and less so on drier stands. Typical species include <i>Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Clintonia borealis, Coptis trifolia, Cornus canadensis, Dryopteris carthusiana, Galium triflorum, Gymnocarpium dryopteris, Maianthemum canadense, Mitella nuda, Streptopus lanceolatus, Trillium undulatum</i>, and <i>Trientalis borealis</i>. Mosses include <i>Sanionia uncinata (= Drepanocladus uncinatus), Hylocomium splendens, Plagiomnium cuspidatum, Pleurozium schreberi, Ptilium crista-castrensis</i>, and <i>Rhytidiadelphus triquetrus</i>. |

This community occurs on fine-sandy stream terraces in the West Gulf Coastal Plain of Louisiana and Texas. The open canopy is dominated by Pinus palustris, although examples in eastern Texas may also include Pinus echinata or Pinus taeda. The subcanopy includes scattered Quercus incana, Quercus stellata, and Quercus marilandica, with Quercus margarettiae also present in Texas examples. Shrubs include Sassafras albidum, Erythrina herbacea and Yucca louisianensis. Herbs include Schizachyrium scoparium, Liatris elegans, Opuntia humifusa, Palafoxia texana var. ambigua, Gaillardia aestivalis, Tridens carolinianus, Pityopsis graminifolia, Monarda punctata, Chrysopsis mariana, and Tetragonotheca ludoviciana. |

This hemi-boreal white-cedar - mixed conifer swamp forest is found in the northern Great Lakes region of the United States and Canada. Stands occur on level to gently sloping ground with wet, organic or mineral soil. It is typically along the margins of peatlands, in drainage courses, shores of lakes and rivers above flooding level, or in shallow depressions. The groundwater is moderately minerotrophic and has circumneutral pH. The canopy is often moderately dense to dense. The understory structure consists of high hummocks and deep, water-filled hollows, with fallen, moss-covered logs common. <i>Thuja occidentalis</i> is moderately to strongly dominant in the canopy, or <i>Picea mariana</i> may overtop the subdominant <i>Thuja occidentalis</i>. Other species include <i>Abies balsamea, Acer rubrum, Betula papyrifera, Fraxinus nigra, Larix laricina</i> and, more rarely, <i>Picea glauca</i>, or <i>Tsuga canadensis</i>. The shrub layer in this community is sparse to dense, in inverse proportion to the tree canopy. Species present in this stratum include <i>Alnus incana, Chamaedaphne calyculata, Cornus canadensis, Cornus sericea, Gaultheria hispidula, Ledum groenlandicum, Linnaea borealis, Rosa acicularis, Rubus pubescens</i>, and <i>Vaccinium myrtilloides</i>. <i>Nemopanthus mucronatus</i> and <i>Viburnum nudum var. cassinoides</i> are more common eastward. The most common herbaceous species are <i>Carex</i> spp. (including <i>Carex disperma), Coptis trifolia, Clintonia borealis, Dryopteris carthusiana, Galium triflorum, Maianthemum canadense, Mitella nuda, Trientalis borealis</i>, and <i>Viola renifolia</i>. Mosses include <i>Hylocomium splendens, Pleurozium schreberi, Ptilium crista-castrensis, Rhytidiadelphus triquetrus, Sphagnum capillifolium, Sphagnum girgensohnii</i>, and <i>Sphagnum magellanicum</i>. Moss cover may be thin where the canopy is very dense. Diagnostic species include <i>Thuja occidentalis</i> as a dominant/codominant species, with a combination of acidic and minerotrophic understory species, such as <i>Alnus incana</i> and <i>Cornus sericea</i>. |
