This association includes sandplain heathlands of the northeastern Atlantic coast dominated by heath shrubs. They occur on nutrient-poor, sandy/gravelly moraine and outwash plains near the coast and are affected by onshore winds and salt spray. Dwarf-shrubs are often dominant, especially <i>Vaccinium angustifolium, Vaccinium pallidum, Arctostaphylos uva-ursi</i>, and <i>Gaylussacia baccata</i>. Associated species include <i>Vaccinium myrtilloides, Hudsonia ericoides, Comptonia peregrina, Kalmia angustifolia, Baptisia tinctoria</i>, or <i>Rubus hispidus</i>. <i>Corema conradii</i> may be locally abundant. The herbaceous layer is similar to sandplain grasslands, only less diverse. Common species include <i>Deschampsia flexuosa, Schizachyrium littorale, Carex pensylvanica, Lespedeza</i> spp., <i>Solidago puberula, Viola sagittata var. ovata (= Viola fimbriatula), Eurybia spectabilis (= Aster spectabilis), Viola pedata, Comandra umbellata, Epigaea repens, Tephrosia virginiana, Gaultheria procumbens, Juncus greenei, Ionactis linariifolius, Helianthemum dumosum, Liatris scariosa var. novae-angliae, Sericocarpus asteroides, Solidago nemoralis, Euthamia</i> spp., and others. Graminoids do not form extensive turf. Small to locally abundant patches of tall shrubs are often present, including <i>Quercus ilicifolia, Photinia pyrifolia (= Aronia arbutifolia), Corylus cornuta, Prunus maritima, Rubus flagellaris, Rosa carolina, Rosa virginiana</i>, or <i>Morella pensylvanica (= Myrica pensylvanica)</i>. |

Phalaris arundinacea Eastern Herbaceous Vegetation

This association is found throughout the northeastern United States and Canada, but its distribution as a natural type is complicated elsewhere. <i>Phalaris arundinacea</i> is native to the United States and Canada but is now more widely distributed and abundant because of local introductions from both local and European populations. The introduced strains may be more aggressive ecotypes than native strains. Stands are found in both minerotrophic basin wetlands as well as rivershores. <i>Phalaris arundinacea</i> has been widely used as a forage and hay crop, especially in marshes and floodplains, and it is used for wildlife food and for shoreline and ditch stabilization. Stands are dominated by <i>Phalaris arundinacea</i>, a 0.5- to 2-m tall perennial grass, which tends to occur in monocultures or associated with <i>Calamagrostis canadensis</i>. Associates in the glaciated Northeast include <i>Viburnum nudum, Alnus incana</i> or <i>Alnus serrulata, Viburnum dentatum</i>, and <i>Agrostis gigantea</i>. In Central Appalachian bottomland old fields, characteristic associates include <i>Verbesina alternifolia</i> (which may be codominant), <i>Solidago rugosa, Boehmeria cylindrica</i>, and <i>Euthamia graminifolia</i>, along with exotic species such as <i>Glechoma hederacea, Coronilla varia, Rosa multiflora</i>, and <i>Elaeagnus umbellata</i>. Midwest associates include species characteristic of wet meadows. <i>Phalaris arundinacea</i> can displace native species over time. Further work is required to resolve the natural versus introduced nature of this type in the Southeast before a description can be completed. |

Schoenoplectus acutus Herbaceous Vegetation

This association is a common emergent herbaceous wetland found mostly in the interior western U.S. ranging from the Puget Sound of Washington to Montana south to California, Nevada and Utah. Stands occur along low-gradient, meandering, usually perennial streams, river floodplain basins, and around the margins of ponds and shallow lakes especially in backwater areas. Some sites are flooded most of the year with about 1 m of fresh to somewhat saline or alkaline water. Other sites, however, dry up enough in late summer to where the water table drops below the ground surface, though the soils are still partially saturated. Soils are generally deep, organic, alkaline, poorly drained and fine-textured, but range in soil textures from sand to clay to organic muck. The soils may be normal or saline. Vegetation is characterized by a dense tall herbaceous vegetation layer 1-3 m tall that is dominated by Schoenoplectus acutus (= Scirpus acutus), often occurring as a near monoculture. Associated species include low cover of Mentha arvensis, Polygonum amphibium, Sagittaria latifolia, and species of Carex, Eleocharis, Rumex, and Typha. Early in the growing season or at permanently flooded sites, aquatic species such as Potamogeton spp. and Lemna minor may be present to abundant. Stands of this association contain no tree or shrub layer, but a few sites have been invaded by the introduced shrub Tamarix spp. |

This red spruce woodland of the Northern Appalachians occurs primarily on acidic bedrock outcrops or summits. Soil development is restricted to crevices or sheltered areas interspersed with significant amounts of exposed bedrock. What soils are present are shallow, well-drained to excessively drained, acidic, coarse sands. Elevations of known examples range from near sea level at the coast to 305-760 m (1000-2500 feet) inland. The canopy is patchy and open, with areas of moderate canopy cover interspersed with areas of sparse vegetation and much open rock. Taken over a large area, woodland structure (25-60% canopy cover) is evident. Tall shrubs and herb are sparse. The dwarf-shrub layer is of variable cover, and may be locally extensive, as may bryoids. Canopy trees are primarily <i>Picea rubens</i> and <i>Abies balsamea</i>, with <i>Pinus strobus</i> occasionally codominant. Associated tree species include <i>Betula papyrifera var. papyrifera, Betula papyrifera var. cordifolia, Pinus rigida, Thuja occidentalis</i>, and <i>Picea mariana</i>. Typical tall shrubs are <i>Sorbus americana, Sorbus decora, Viburnum nudum var. cassinoides, Nemopanthus mucronatus, Photinia melanocarpa (= Aronia melanocarpa)</i>, or <i>Amelanchier</i> spp. <i>Morella pensylvanica (= Myrica pensylvanica)</i> and <i>Picea glauca</i> may be present in this community near the seacoast. The low heath layer is made up of <i>Vaccinium angustifolium, Vaccinium myrtilloides, Gaylussacia baccata</i>, and <i>Kalmia angustifolia</i>. Forbs and graminoids include <i>Deschampsia flexuosa, Danthonia spicata, Piptatherum pungens (= Oryzopsis pungens), Sibbaldiopsis tridentata, Solidago simplex var. randii</i>, and <i>Maianthemum canadense</i>. Bryoids include <i>Cladina</i> spp., <i>Pleurozium schreberi, Dicranum polysetum, Polytrichum juniperinum, Polytrichum piliferum</i>, and <i>Polytrichum commune</i>. Ground cover is sparse needle litter and exposed bedrock. This association occurs on bedrock ridges and outcrops, compared to the floristically similar ~<i>Picea rubens / Ribes glandulosum</i> Woodland (CEGL006250)$$, which occurs on talus. |

These shrublands occur along large streams and rivers in New England, northern New York and western Pennsylvania. They are found on river-margin alluvial deposits of moderate-energy reaches, where the flooding regime prevents forests from developing. The setting can range from flats to moderately steep banks; soils are usually sandy or silty and have little organic matter. Most are temporarily flooded, and the soils may not remain saturated through the entire growing season. Tall shrubs (1.5-3 m in height) dominate the vegetation, usually forming at least 50% cover and often creating a dense thicket. The amount of lower shrub and herb vegetation varies inversely with the tall-shrub canopy. Bryophytes are usually sparse but may be locally abundant in some settings. <i>Alnus incana</i> is a constant and usually dominant shrub. In some cases, <i>Alnus serrulata</i> (in more temperate settings) or <i>Alnus viridis</i> (in more boreal settings) may occur with or in place of <i>Alnus incana</i>. The ability of alders to bend under strong currents and their nitrogen-fixing root nodules may give alders a competitive advantage over other shrubs in this setting. <i>Cornus sericea</i> or <i>Cornus amomum</i>, along with <i>Salix</i> spp., are frequent associates and may dominate in some areas. <i>Viburnum nudum var. cassinoides</i> is occasional but not abundant. <i>Acer rubrum, Prunus serotina, Ulmus americana</i>, and/or <i>Acer saccharinum</i> may be present, as sparse individuals; in more southerly examples of this type, <i>Acer negundo</i> and <i>Salix nigra</i> may occur. <i>Spiraea alba</i> is usually present and may be abundant as a lower shrub. <i>Clematis virginiana</i> is a typical vine, often clambering in tangles on the shrubs. This type is distinguished from other northeastern <i>Alnus</i>-dominated associations by its alluvial setting. Although common, this association is little studied and comprehensive surveys have yet to be undertaken. |
