This shrub fen community is potentially found in the northern Great Lakes region of the United States and Canada. It has not been well described by any authors. Stands are dominated by the deciduous shrub Myrica gale. Codominates may include Chamaedaphne calyculata in more nutrient-poor examples, and Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda) in richer examples. Further work is needed to determine the characteristics of this type. |

This Central Appalachian community type occurs throughout the Blue Ridge and Ridge and Valley portions of the Virginia mountains north of the New River and may extend throughout the Central Appalachian portions of West Virginia, Maryland, and Pennsylvania. Stands occupy mesic hollow sideslopes, ravines, and slope concavities at elevations from 240-800 m (800-2600 feet) and exceptionally to 1000 m (3300 feet). Underlying bedrock is variable and probably exerts less influence on vegetation than local soil conditions. Stands are associated both with sheltered sites on poor substrates, such as acidic sandstones, and with warmer, more exposed coves on fertile substrates. Vegetation consists largely of post-logging secondary forests with tall (>30 m), well-formed canopy trees. <i>Liriodendron tulipifera</i> is the characteristic, usually dominant canopy species in mixed stands with <i>Magnolia acuminata, Quercus rubra, Acer rubrum</i>, and <i>Carya ovalis</i>. <i>Quercus prinus (= Quercus montana), Fraxinus americana, Betula lenta, Tilia americana</i> (including both <i>var. americana</i> and <i>var. heterophylla</i>), <i>Carya glabra, Carya alba</i>, and <i>Quercus alba</i> are minor canopy associates. Understory tree layers are very open and contain young reproduction of the canopy species along with <i>Cornus florida</i> (often dominant) and <i>Ostrya virginiana</i>. <i>Cornus florida, Viburnum acerifolium</i>, and climbing or scrambling <i>Parthenocissus quinquefolia</i> are usually the most abundant species of a sparse shrub layer. The herb layer varies in density from open to moderately dense, but generally lacks the lush aspect of other communities in the Rich Cove and Slope Forests group. |

The known range of this community includes the Central Appalachian region of Virginia, Maryland, and West Virginia, and the northern and central Piedmont of Virginia. The type is particularly abundant and widespread on low shale mountains and hills in west-central Virginia and adjacent West Virginia. Sites are underlain primarily by shale and similar sedimentary rocks (siltstone, metasiltstone, phyllite) or, less commonly, sandstone in the mountains and by a variety of acidic metamorphic and igneous rocks in the Piedmont. Stands occupy middle and upper slopes, ridge crests, dry ravines, and bluffs, mostly below 760 m (2500 feet) elevation in the mountains and above 75 m (240 feet) in the Piedmont. Aspect is variable, and site moisture is typically assessed as subxeric or submesic. Vegetation is a mixed forest, with canopies varying from closed to somewhat open, codominated by <i>Pinus strobus</i> (25-75% canopy cover) and various oaks, particularly <i>Quercus alba, Quercus coccinea, Quercus velutina, Quercus rubra</i>, and <i>Quercus prinus</i>. Minor canopy associates include <i>Acer rubrum, Carya alba, Carya glabra, Fagus grandifolia</i> (mostly Piedmont), <i>Liriodendron tulipifera, Nyssa sylvatica, Pinus virginiana, Quercus falcata</i> (mostly Piedmont), <i>Quercus velutina</i>, and <i>Tsuga canadensis</i>. Understory trees include <i>Acer rubrum, Oxydendrum arboreum</i>, and <i>Nyssa sylvatica</i>, which may be abundant, along with <i>Cornus florida</i>. The shrub layer is predominantly ericaceous and varies from sparse and patchy to occasionally dense, with <i>Vaccinium stamineum, Vaccinium pallidum, Gaylussacia baccata</i>, and <i>Kalmia latifolia</i> being characteristic. Other frequent but lower-cover shrub-layer species include <i>Amelanchier arborea, Viburnum acerifolium, Smilax rotundifolia, Smilax glauca, Sassafras albidum</i>, and <i>Diospyros virginiana</i>. The herb layer is characterized by species tolerant of dry, acidic soils; it is usually sparse but occasionally contains dense graminoid patches of <i>Danthonia spicata, Deschampsia flexuosa</i>, or <i>Carex pensylvanica</i>.<br /> |

Populus fremontii / Sparse Forest

This mature forest association is known only from the San Francisco River watershed, although it likely occurs to a limited extent elsewhere in southwestern New Mexico and southeastern Arizona. It is found within the floodplain of large, lowland valleys at elevations around 1500 m (5000 feet). Sites are typically alluvial terraces that are rarely flooded (25- to 100-year recurrence interval and discharge ratios of 3.6 to 11.2). In keeping with the high landscape position, soils are deep but sandy and relatively dry (sandy and sandy-skeletal Oxyaquic Ustifluvents). Mature Populus fremontii form dense canopies (>60% cover) with only scattered representatives of other floodplain tree species. Although 20 undergrowth species have been recorded for the association, only Baccharis salicifolia and Melilotus officinalis are known to exceed 1% cover. The relatively dry environment combined with shading likely drive the low understory diversity. As a keystone species, the reproduction of Populus fremontii after flooding (and sufficient subsequent base flows) is critical to the sustainability of this community. |

This community is currently known from a narrow range in the Northern Blue Ridge and adjacent inner Piedmont of Virginia, Maryland, and West Virginia. It is restricted to the western Piedmont foothills and lower- to middle-elevation slopes and spurs of the main Blue Ridge. Elevation ranges from 140 to 950 m (450-3100 feet). The type is generally associated with base-rich soils weathered from mafic igneous and metamorphic rocks, including metabasalt, amphibolite, pyroxene-bearing granulite, charnockite, and actinolite schist. It also occurs less frequently on granitic rocks and calcareous metasiltones and phyllites. Habitats are more-or-less rocky, gentle to steep, submesic to subxeric slopes with a wide range of aspects. Midslope topographic positions are typical, but stands occasionally occur on lower or upper slopes and crests. This association is a true oak-hickory forest with mixed canopy dominance by several <i>Quercus</i> spp. and <i>Carya</i> spp. <i>Carya ovalis, Quercus rubra</i>, and <i>Quercus prinus</i> are consistent codominants and have the highest importance values based on standard forestry statistics generated from stem-diameter measurements. <i>Quercus alba, Quercus velutina, Carya alba, Carya glabra, Fraxinus americana</i>, and <i>Liriodendron tulipifera</i> are less constant canopy species but achieve codominance in some stands. <i>Carya</i> spp., <i>Quercus</i> spp., <i>Acer rubrum, Nyssa sylvatica, Fraxinus americana</i>, and <i>Sassafras albidum</i> are well-represented in lower tree strata. <i>Cercis canadensis</i> (at lower elevations) and, to a lesser extent, <i>Cornus florida</i> dominate the shrub and lowest tree layers, while <i>Viburnum acerifolium</i> is a common low shrub. A large number of herbaceous species occur in the type. |

This herbaceous community occurs in the Pine Barrens of New Jersey on the floodplains of Outer Coastal Plain rivers and streams. It is often found in expanses bordered by woody herbaceous savanna. Microtopography is tussocky, with dwarf Atlantic white-cedar on the low-graminoid tussocks and a remarkable diversity of herbaceous and bryophyte species on the hummocks and in the hollows. The visual impression of this community is a sedge meadow with the scattered yellow and white fuzzy flowers of Lophiola aurea and white flowers of Sabatia difformis. This community is stable in undisturbed sites as well as historically disturbed sites on a variety of substrates including peat, bog iron muck, or quartzite sand. Groundwater seepage is the primary hydrologic force with occasional riverine flooding. Dominant species include Rhynchospora alba, Rhynchospora cephalantha, Muhlenbergia uniflora, Lophiola aurea, and Sarracenia purpurea. Associated dwarf woody species include Chamaecyparis thyoides and Ilex glabra.
