These open forests dominated by <i>Taxodium distichum</i> and <i>Platanus occidentalis</i> occur along rocky banks of the lower Mountain Fork of the Red River in the Ouachita Mountain foothills. These forests are also known from the Saline and Maumelle rivers, and perhaps in other small rivers that flow into the Arkansas River. Other trees include <i>Betula nigra, Liquidambar styraciflua</i>, and less commonly <i>Carya aquatica, Ulmus</i> spp., <i>Celtis</i> spp., and <i>Fraxinus pennsylvanica</i>. These forests occur in a complex with shrublands dominated by <i>Juniperus virginiana var. virginiana, Ilex vomitoria, Cornus obliqua</i>, and <i>Salix caroliniana</i> and open grasslands with <i>Calamovilfa arcuata, Panicum virgatum</i>, and <i>Schizachyrium scoparium</i>. More information is needed to better name this association. Alliance placement must also be examined. |

Liquidambar styraciflua - Acer rubrum / Carex spp. - Sphagnum spp. Forest

This association is designed to accommodate a variety of isolated, poorly understood seasonally flooded forests of upland depressions in the Southern Blue Ridge and the adjacent and submontane Piedmont. This includes an example in Cades Cove in the Great Smokies National Park, an example in the Piedmont portion of the Chattahoochee National Forest (Georgia), the Bankhead National Forest (Alabama). Stands assigned to this concept are dominated by some combination of <i>Liquidambar styraciflua</i> and/or <i>Acer rubrum</i>, possibly with <i>Nyssa sylvatica</i> and/or <i>Liriodendron tulipifera</i>. Some shrubs that may be found include <i>Cornus amomum, Cornus foemina</i>, and <i>Alnus serrulata</i>. Some woody vines which are possible components include <i>Berchemia scandens, Decumaria barbara</i>, and <i>Smilax laurifolia</i>. Herbs (which may be abundant to sparse) include <i>Carex intumescens, Carex</i> spp., <i>Chasmanthium sessiliflorum, Dichanthelium dichotomum var. dichotomum, Dichanthelium</i> spp., <i>Leersia</i> spp., <i>Rhynchospora capitellata, Mitchella repens</i>, and <i>Arisaema triphyllum</i>. Some sites may have ground layers dominated by vascular plants (especially graminoids), others dominated by <i>Sphagnum</i> spp. One of the <i>Sphagnum</i> species associated with these forests may be a disjunct Coastal Plain species, <i>Sphagnum cuspidatum (= var. floridanum)</i>. The variable composition of stands assigned here and the lack of understanding of the dynamics of this type (successional trends, disturbance, hydrology) mean that the type is somewhat poorly defined. More information is needed. |

Planera aquatica Forest

Southeastern Ecology Working Gro... |

|
This association consists of forests of the southeastern United States Coastal Plain in which <i>Planera aquatica</i> is dominant and may form an essentially monospecific canopy. Relatively few additional species are present in other vegetational strata, although these short-statured forests sometimes have a scattered emergent canopy of other tree species typical of flooded swamps. The herbaceous and vine/liana strata are sparse, and no species are known to be diagnostic of this type relative to other bottomlands. Due in part to extreme periods of inundation, this habitat is typically very low in species diversity. |

This sparse woodland association occurs on low- to mid-elevation hogbacks, colluvial slopes and badlands in the Colorado Plateau of western Colorado and eastern Utah. Elevations range from 1488 to 1997 m (4880-6550 feet), and most sites are on cooler north and east aspects. Slopes may be gentle to moderately steep (3-46% slope) and are generally underlain by Mesozoic marine shales of the Morrison Formation or Mancos shale. Colluvium from sandstone cliffs or outcrops upslope from the stand may cover the ground surface. Soils are rapidly drained and may be sandy loams or silty clays. The vegetation is characterized by a sparse to open canopy of <i>Juniperus osteosperma</i> with between 1 and 25% cover. <i>Pinus edulis</i> is either absent or present in very low amounts in the canopy, although <i>Juniperus osteosperma</i> and <i>Pinus edulis</i> seedlings may be present. There is no shrub layer, but scattered short and dwarf-shrubs may total up to 10% cover in more heavily vegetated stands. Common species include <i>Atriplex confertifolia, Artemisia bigelovii, Artemisia nova, Artemisia tridentata ssp. wyomingensis, Chrysothamnus viscidiflorus, Gutierrezia sarothrae, Glossopetalon spinescens var. meionandrum, Ephedra viridis, Gutierrezia sarothrae, Krascheninnikovia lanata, Opuntia erinacea, Opuntia polyacantha, Shepherdia rotundifolia</i>, and <i>Yucca harrimaniae</i>. The herbaceous layer is dominated by <i>Leymus salinus</i> with between 1 and 25% cover. The remainder of the herbaceous cover is sparse but diverse. Additional graminoids present include <i>Achnatherum hymenoides, Pleuraphis jamesii, Poa fendleriana</i>, and <i>Poa secunda</i>. Forbs include <i>Arenaria hookeri, Arenaria fendleri, Calochortus gunnisonii, Cymopterus bulbosus, Cymopterus purpureus, Eriogonum umbellatum, Leptodactylon pungens, Lepidium montanum, Oenothera pallida, Phlox austromontana, Petradoria pumila, Phlox hoodii, Sphaeralcea coccinea, Streptanthella longirostris, Stenotus acaulis</i>, and <i>Xylorhiza venusta</i>. |

This floodplain swamp forest is the 'matrix' community of the Meadow River wetlands in southeast West Virginia. It is dominated by <i>Quercus palustris</i> in association with <i>Acer rubrum, Carya ovata, Fraxinus americana, Fraxinus nigra, Nyssa sylvatica</i>, and <i>Quercus bicolor</i>. The shrub layer is dominated by <i>Carpinus caroliniana, Cornus amomum, Ilex verticillata, Lindera benzoin</i>, and <i>Viburnum dentatum</i>. Abundant species in the herbaceous layer include <i>Boehmeria cylindrica, Carex bromoides, Carex stricta, Cinna arundinacea, Leersia oryzoides, Lycopus uniflorus, Osmunda regalis, Onoclea sensibilis, Pilea pumila, Packera aurea (= Senecio aureus)</i>, and <i>Toxicodendron radicans</i>. Its relation to pin oak swamps elsewhere in West Virginia and in other states has not been determined. |
