This white pine - red maple swamp forest type is found in the southern Great Lakes region of the United States and Canada. Stands occur on sites with at least a thin layer of organic material on the surface. Glacially deposited sand usually lies beneath the organic layer. The overstory is dominated by Pinus strobus and may contain Acer rubrum, Betula alleghaniensis, Tsuga canadensis, and Ulmus americana. Shrubs can be sparse, but include Alnus incana and Ilex verticillata. Understory species include Carex spp., Osmunda cinnamomea, Osmunda regalis, and Symplocarpus foetidus. Sphagnum spp. may occur as a ground cover. In Wisconsin, common species include Carex folliculata and Thelypteris simulata, which are more common in the eastern United States. |

This association includes forests of protected coves in the southern Appalachian Mountains of eastern Tennessee, western North Carolina, and southwest Virginia. This type extends peripherally into the Cumberland Mountains and Ridge and Valley of southwestern Virginia. These forests are associated with nutrient-rich soils and, often, mafic geologies, and occur on steep, middle to low protected slopes and coves at 610-1400 m (2000-4600 feet) elevation. Examples of this association have deciduous forest canopies dominated by either <i>Acer saccharum, Aesculus flava, Fraxinus americana, Halesia tetraptera var. monticola</i>, or <i>Tilia americana var. heterophylla</i>, or by various combinations of these species. Other common canopy species can include <i>Carya cordiformis</i> and <i>Quercus rubra</i>. A shrub stratum is very sparse or absent, and the herbaceous stratum is dense and luxurious, with high species richness. The defining feature of this association is the lush herbaceous flora with many calciphilic species indicative of high pH or circumneutral soils. Characteristic species include <i>Asarum canadense, Carex plantaginea, Cymophyllus fraserianus, Cystopteris protrusa, Deparia acrostichoides, Diplazium pycnocarpon, Prosartes lanuginosa (= Disporum lanuginosum), Dryopteris goldiana, Hepatica nobilis var. acuta, Hydrophyllum canadense, Osmorhiza claytonii, Solidago flexicaulis</i>, and <i>Viola canadensis</i>. The herbaceous stratum can have local dominance by <i>Laportea canadensis, Viola canadensis, Dryopteris intermedia, Actaea podocarpa (= Cimicifuga americana), Actaea racemosa (= Cimicifuga racemosa)</i>, and <i>Caulophyllum thalictroides</i>. This forest lacks dominance by <i>Betula alleghaniensis</i> and <i>Fagus grandifolia</i>, and has an herbaceous flora indicative of high-base status soils. This association typically has a much more diverse herbaceous stratum than other deciduous cove forests of the Southern Blue Ridge. |

Vegetation within this alliance occurs in cold, snowy subalpine environments of high coastal mountains. It has been reported from Washington and British Columbia, but probably also occurs northward. It occurs from 760-1220 m in elevation, primarily west of the Cascade crest where maritime climate influence is strong and deep winter snowpacks are typical. Precipitation ranges from 150-400 cm annually, falling largely as snow, and snowpacks usually linger into June or later. These forests typically occur in subalpine habitats near the ecotone with subalpine parklands. Sites are cold, poorly drained and saturated because of shallow subirrigation, seeps, springs or small streams. Stands are found on gentle, lower slopes, toeslopes, and valley bottoms with typically eastern and northern aspects. Substrates are moderately deep soils derived from colluvium, alpine till, glacial outwash, with volcanic ash overlaying granite. These soils are acidic, coarse-textured with a substantial organic component because of high moisture and low temperatures. Vegetation included in this forest alliance has a closed tree canopy 20-35 m tall that is dominated by ~Tsuga mertensiana$ and ~Abies amabilis$. Other common trees include ~Tsuga heterophylla$ and ~Chamaecyparis nootkatensis$. The shrub layer is moderately dense and is dominated by ericaceous species such as ~Vaccinium ovalifolium$ and ~Oplopanax horridus$. Other common shrubs include ~Rubus pedatus, Rubus spectabilis, Ribes bracteosum, Menziesia ferruginea$, and ~Vaccinium membranaceum$. The sparse herbaceous layer is dominated by shade-tolerant forbs and ferns, such as ~Tiarella trifoliata var. unifoliata, Clintonia uniflora, Streptopus lanceolatus var. curvipes (= Streptopus roseus), Athyrium filix-femina, Blechnum spicant$, and ~Gymnocarpium dryopteris$. Adjacent stands include forests dominated by ~Tsuga heterophylla$ or ~Pseudotsuga menziesii$ at lower elevations and ~Abies lasiocarpa$ at higher elevations. |

This vegetation occupies depressions of Piedmont and mountain floodplains, as well as broad flat floodplains of the Coastal Plain of Delaware and New Jersey. These depressions are usually abandoned channel segments or swales behind natural levees in which water is ponded for all or much of the year. Water may be supplied primarily by stream flooding or by rainfall. Vegetative cover is variable and may be confined to edges or shallower portions that dry out during the growing season. The vascular plant species vary widely among examples. Emergent vegetation may include <i>Peltandra virginica, Dulichium arundinaceum</i>, and <i>Polygonum</i> spp. <i>Carex crinita</i> or some other wetland <i>Carex</i> species are almost always present. <i>Saururus cernuus</i> and <i>Boehmeria cylindrica</i> are other typical herbs. Larger examples may have pad-leaved aquatic species such as <i>Brasenia schreberi</i> or <i>Nymphaea odorata</i>. Some examples have wetland shrubs on edges or in shallow portions, including <i>Cornus amomum</i> and <i>Cephalanthus occidentalis</i>. The moss <i>Climacium americanum</i> is often abundant on the landward side. |
