Reference:

Description:
This subboreal 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, 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, Hylocomium splendens, Plagiomnium cuspidatum, Pleurozium schreberi, Ptilium crista-castrensis</i>, and <i>Rhytidiadelphus triquetrus</i>.
