The dwarf-shrub (less than 0.5 m), <i>Vaccinium macrocarpon</i>, may be scattered throughout or be locally dominant. Typical dominants are <i>Carex echinata, Solidago patula var. patula, Carex leptalea, Carex atlantica, Rhynchospora capitellata, Scirpus atrovirens, Osmunda cinnamomea, Lysimachia terrestris, Vaccinium macrocarpon, Eriophorum virginicum</i>, and <i>Polytrichum commune</i>. Other characteristic species are <i>Arethusa bulbosa, Aulacomnium palustre, Bazzania trilobata, Calopogon tuberosus, Carex folliculata, Carex gynandra, Carex trisperma, Chelone cuthbertii, Juncus effusus, Juncus subcaudatus, Lilium grayi, Melanthium virginicum, Orontium aquaticum, Osmunda regalis var. spectabilis, Oxypolis rigidior, Parnassia asarifolia, Platanthera grandiflora, Poa paludigena, Rhizomnium appalachianum, Sagittaria latifolia (= var. pubescens), Scirpus cyperinus, Scirpus expansus, Scirpus polyphyllus, Packera aurea (= Senecio aureus), Sphagnum bartlettianum, Sphagnum fallax, Sphagnum affine (= Sphagnum imbricatum), Sphagnum palustre, Sphagnum recurvum, Spiraea alba, Spiraea tomentosa, Stenanthium gramineum var. robustum, Thelypteris palustris var. pubescens, Thelypteris simulata</i> (rarely), and <i>Rhizomnium appalachianum</i>. This community can occur on flat areas, in portions of valley bottoms that are not subject to flooding, but maintained hydrologically by rainwater and a high water table, or in the upper portions of stream watersheds, on slight slopes, hydrologically maintained by very nutrient-poor to fairly nutrient-rich seepage.
Comm #4992	Bromus inermis Semi-natural Herbaceous Alliance » more details accession code: VB.CC.28448.BROMUSINERMISSE	Midwestern Ecology Working Group...	0	This introduced-species grassland alliance occurs widely throughout the northern Great Plains of the United States, and perhaps more widely in the Midwest and Canada. It likely occurs throughout much of the Rocky Mountains and Intermountain West. In semi-arid environments, it is restricted to relatively mesic conditions such as in riparian areas or forest openings at montane elevations. Stands can occur in a wide variety of human-disturbed habitats, including highway rights-of-way, jeep trails, etc. Bromus inermis is also widely planted for cover, pasture, and hay, and has escaped into a variety of habitats. The vegetation is dominated by medium-tall (0.5-1 m) perennial graminoids. The dominant grass is Bromus inermis, a naturalized species from Eurasia. Other weedy species may occur as well, but native species are generally less than 10% cover. Native species may include mixed-grass prairie grasses, such as Pascopyrum smithii and Hesperostipa comata (= Stipa comata), as well as others. Where native species are conspicuous enough to identify the native plant association that could occupy the site, the stand should be typed as such.
Comm #4993	Chamaedaphne calyculata - Vaccinium macrocarpon / Carex striata var. striata - Woodwardia areolata Dwarf-shrubland » more details accession code: VB.CC.36210.CEGL004165	Southeastern Ecology Working Gro...	0	Dwarf-shrub/herbaceous openings forming a mosaic with ~<i>Ilex glabra - Lyonia lucida - Zenobia pulverulenta</i> Shrubland (CEGL003944)$$ in the wettest low pocosins of peat domes (ombrotrophic blanket bogs) of the outer Coastal Plain of North Carolina. Other characteristic species include <i>Vaccinium macrocarpon, Rhynchospora alba, Polygala brevifolia</i>, and <i>Chamaedaphne calyculata</i>.
Comm #4994	(Quercus sinuata) / Sorghastrum nutans - Ratibida pinnata - Hedyotis nigricans var. nigricans - (Glandularia bipinnatifida) Georgia Chalk Prairie Herbaceous Vegetation » more details accession code: VB.CC.34837.CEGL004247	Southeastern Ecology Working Gro...	0	This herbaceous association includes tallgrass prairies on the Fort Valley Plateau of Houston, Peach, Twiggs, and Bleckley counties in the South Atlantic Coastal Plain of Georgia on "gumbo flats" over Sumter soils. There is substantial variation in composition due to edaphic factors, fire suppression and disturbance. This community occurs on calcareous soils of the Dry Branch, Tivola and Ocmulgee formations of late Eocene origin. The Ocmulgee Formation, previously known as Cooper Marl in Georgia, is a combination of indurated and argillaceous limestone that also falls within the Ocala Group. Calcareous soils are the main abiotic factor driving the occurrence of blackland prairie vegetation within Georgia. The shrink-swell clays and alkaline pH of these soils account for a distinctive suite of vegetation not found elsewhere in the state. The Sumter Series most commonly underlies these prairie sites and consists of shallow, alkaline, moderately well-drained silty clays underlain by marl, chalk, or limestone. The Oktibbeha, Boswell, and Susquehanna series are also present to a lesser extent and occur together in intricate patterns. The nine prairies found on Ocmulgee Wildlife Management Area and Oaky Woods Wildlife Management Area represent the only blackland prairies in Georgia occurring on protected lands. These areas may be subjected to development if the currently projected (2008) transfer of leased timberland to private interests occurs.<br><br>The dominant vegetation consists of a variety of native grasses usually dominated by <i>Sorghastrum nutans</i>. Other important grasses include <i>Andropogon gerardii, Aristida purpurascens, Eragrostis spectabilis, Muhlenbergia capillaris, Sporobolus clandestinus, Sporobolus junceus, Sporobolus vaginiflorus, Tridens flavus</i>, and <i>Tripsacum dactyloides</i>. The disjunct prairie grass <i>Bouteloua curtipendula</i> is present in at least one occurrence. In addition, a large number of state-listed rare or disjunct prairie herbaceous perennials also occur. Prominent among these are <i>Draba cuneifolia, Galium virgatum, Glandularia bipinnatifida, Ophioglossum engelmannii, Polygala boykinii, Scutellaria drummondii, Spermolepis inermis, Symphyotrichum georgianum, Symphyotrichum laeve var. concinnum, Symphyotrichum novae-angliae</i>, and <i>Thaspium barbinode (= Thaspium chapmanii)</i>. Woody cover in these grasslands varies considerably due to edaphic factors, disturbance and fire suppression. Characteristic species that might be abundant to sparse include <i>Celtis tenuifolia, Cercis canadensis, Cornus asperifolia, Crataegus crus-galli, Crataegus spathulata, Crataegus triflora, Diospyros virginiana, Frangula caroliniana (= Rhamnus caroliniana), Fraxinus americana, Juniperus virginiana, Quercus muehlenbergii, Quercus sinuata, Sideroxylon lanuginosum (= Bumelia lanuginosa), Ulmus alata</i>, and <i>Viburnum rufidulum</i>. Common vines include <i>Berchemia scandens</i> and <i>Cocculus carolinus</i>.
Comm #4995	Pinus echinata - Quercus (alba, rubra) / Vaccinium (arboreum, pallidum) / Schizachyrium scoparium - Chasmanthium sessiliflorum - Solidago ulmifolia Forest » more details accession code: VB.CC.22040.PINUSECHINATAQU	Southeastern Ecology Working Gro...	0	This upland, subxeric to submesic shortleaf pine - oak forest community is the matrix forest community of the Ouachita Mountains and surrounding areas, ranging from eastern Oklahoma to western Arkansas and southern Missouri. Stands occur on upper to middle, south-facing slopes, saddles, and flatter ridgelines. Soils are shallow to deep (25-100 cm). Parent material is a variety of sandstone and mixed sandstone-shale-derived substrates, or, in parts of the Missouri Ozarks, chert substrates. The canopy is dominated by Pinus echinata codominating with Quercus alba, Quercus rubra, or Quercus velutina, either singly or in combination. Shortleaf pine often forms an emergent canopy over the oaks. Carya texana or Cornus florida are typical subcanopy components. Other trees in the canopy and subcanopy can include Acer rubrum, Amelanchier arborea, Carya alba, Nyssa sylvatica, Ostrya virginiana, Quercus falcata, and Quercus stellata. There is little understory, and the shrub layer is typically open with Vaccinium pallidum common as a low shrub and Vaccinium arboreum as a locally abundant tall shrub. Other species in the shrub stratum vary among occurrences but can include Callicarpa americana, Lyonia ligustrina, Morus rubra, Sassafras albidum, Styrax americanus, and Ulmus alata, and the vines Smilax glauca, Smilax bona-nox, Smilax rotundifolia, Toxicodendron radicans, and Vitis rotundifolia. The density of the herbaceous stratum varies with age of the stand and disturbance history but increases with fire. Composition of the herbaceous stratum in these forests can be quite diverse but tends to vary among occurrences. Most examples of this association exist with sparse shrub and herb strata and ground cover dominated by leaf litter. Typical herbaceous species include Antennaria parlinii, Antennaria plantaginifolia, Symphyotrichum anomalum (= Aster anomalus), Symphyotrichum patens (= Aster patens), Brachyelytrum erectum, Chasmanthium latifolium, Chasmanthium sessiliflorum, Danthonia spicata, Desmodium glabellum, Desmodium laevigatum, Desmodium nudiflorum, Desmodium rotundifolium, Dichanthelium linearifolium, Dichanthelium boscii, Dichanthelium commutatum, Helianthus divaricatus, Helianthus hirsutus, Helianthus X laetiflorus, Hieracium gronovii, Hypericum hypericoides ssp. hypericoides, Piptochaetium avenaceum, Schizachyrium scoparium, Solidago hispida, Solidago odora, Solidago ulmifolia, and Viola pedata. Fire increases coverage by grasses (Schizachyrium scoparium and Andropogon gyrans (= Andropogon elliottii)) and legumes. Although this is one of the most widespread forest types in the region, high quality, mature examples are uncommon. Mature, fire-suppressed examples loose the shortleaf pine and fire-tolerant species and show increases in stem density and fire-intolerant species. Mature, fire-maintained examples are extremely rare. Much of this forest community is managed to maintain specific tree densities and overstory composition.
Comm #4996	Pinus virginiana Successional Ruderal Forest » more details accession code: VB.CC.34750.CEGL002591	Southeastern Ecology Working Gro...	0	This successional Virginia pine forest of the southeastern states occurs in areas where canopy removal has created dry, open conditions and bare mineral soil, allowing for the establishment of <i>Pinus virginiana</i>. These habitats include old fields, old pastures, clearcuts, and eroded areas; soils are typically dry, acidic, and infertile. It is common on abandoned farmland. This forest typically has a very dense canopy of <i>Pinus virginiana</i> and little understory vegetation. The dense canopy may also include admixtures of other <i>Pinus</i> species (e.g., <i>Pinus taeda, Pinus echinata, Pinus rigida, Pinus strobus</i>) or other early-successional deciduous trees (e.g., <i>Acer rubrum, Liquidambar styraciflua, Prunus serotina, Liriodendron tulipifera, Fraxinus americana, Nyssa sylvatica</i>). Associated woody and herbaceous species vary with geography but are typically ruderal or exotic species. Shrub and herb layers are frequently very sparse. Stands are short-lived, generally less than 75 years.

Comm #4998	Tsuga canadensis - (Betula alleghaniensis) Forest » more details accession code: VB.CC.36670.CEGL002598	Midwestern Ecology Working Group...	0	This mesic hemlock evergreen forest is found in the Great Lakes region of the United States and Canada. Stands occur on deep, acidic soils that may be poorly drained. The overstory of this community is strongly dominated by <i>Tsuga canadensis</i>, typically around 25 m tall. <i>Betula alleghaniensis</i> is often present in the canopy and subcanopy, but at less than 25% cover. Other species that are a minor component of the canopy include <i>Abies balsamea, Acer rubrum, Acer saccharum, Pinus strobus, Tilia americana</i>, and <i>Thuja occidentalis</i>. The sapling layer may also contain <i>Abies balsamea</i> and <i>Thuja occidentalis</i>, especially in canopy gaps. Shrubs are rare and herbaceous species only moderately abundant under the dense evergreen canopy; however, where gaps occur, <i>Acer pensylvanicum, Acer spicatum, Amelanchier</i> spp., <i>Gaultheria procumbens, Lonicera canadensis</i>, and <i>Rubus idaeus</i> may be moderately abundant. The herbaceous layer is poor under drier, more evergreen stands, and richer under more moist and somewhat deciduous stands. Herbaceous species found in this community include <i>Aralia nudicaulis, Clintonia borealis, Coptis trifolia, Cornus canadensis, Dryopteris carthusiana, Huperzia lucidula (= Lycopodium lucidulum), Maianthemum canadense, Oxalis montana (= Oxalis acetosella), Pteridium aquilinum, Streptopus lanceolatus var. longipes (= Streptopus roseus)</i>, and <i>Trientalis borealis</i>. A sparse to dense moss layer includes <i>Brachythecium reflexum, Callicladium haldanianum, Dicranum flagellare, Dicranum montanum, Mnium marginatum, Plagiothecium laetum, Polytrichum commune, Ptilidium pulcherrimum</i>, and <i>Tetraphis pellucida</i>.

These successional woodlands typically have a total canopy cover between 25 and 50%. The canopy species vary greatly, but Gleditsia triacanthos is always present (in variable amounts), and Ulmus alata or Ulmus rubra is usually present. Other species that may occur in this woodland are Juniperus virginiana var. virginiana, Pinus virginiana, Celtis occidentalis, Celtis laevigata var. laevigata, Liriodendron tulipifera, Liquidambar styraciflua, Juglans nigra, Fraxinus americana, Quercus alba, Quercus stellata, Quercus velutina, Quercus rubra, and Carya spp. Common shrubs are Rhus copallinum and Rubus spp. This successional type results from heavy grazing or other severe disturbance.
Comm #5000	A.333 » more details accession code: VB.CC.1958.A333 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This alliance of floodplains and streamsides in cismontane California requires seasonally flooded, saturated soils. Stands occur from sea level to 2700 m. Because of the Mediterranean climate throughout the range of this alliance, flooding can occur throughout the winter and spring. Annual rainfall totals are between 60 and 80 cm. Stands of this alliance are dominated by ~Salix lucida ssp. lasiandra$ in its tree form. The canopy may also be shared by ~Acer macrophyllum, Populus balsamifera, Populus fremontii, Salix gooddingii, Salix hookeriana, Salix laevigata, Salix sitchensis, Alnus rubra$, and ~Alnus rhombifolia$. Shrubs are typically sparse under the canopy, but many of the tree species in this alliance may also occur in shrub form. Other shrubs that may be present include ~Sambucus mexicana$ and ~Cornus sericea$. The herbaceous layer is highly variable depending on season, length of time since last inundation, and degree of disturbance.
