Comm #5291	Quercus lyrata Pond Forest » more details accession code: VB.CC.18692.QUERCUSLYRATAPO	Southeastern Ecology Working Gro...	0	This overcup oak pond forest is found in the south-central United States in southern Missouri and Arkansas. Stands occur in basins of sinkholes or other isolated depressions on uplands. Soils are very poorly drained, and surface water may be present for extended periods of time, rarely becoming dry. Water depth may average close to 0.5 m in depth. Soils may be deep (100 cm or more), consisting of peat or muck, with parent material of peat, muck or alluvium. These forests are Quercus lyrata-dominated and occur in seasonally flooded ponds in upland situations. These ponds may also have Liquidambar styraciflua and Nyssa biflora in the canopy. These canopy species also occur in the shrub layer with Acer rubrum. Herbaceous species, such as Eleocharis obtusa, can be present in the center of the pond, along with hummocks of Sphagnum. When these ponds draw down, leaf litter can comprise 60-70% of the ground cover, with only scattered herbs on the Sphagnum hummocks and at the bases of trees. Small thickets of Smilax rotundifolia occur around the edges of these ponds and on hummocks, with occasional Vaccinium pallidum. Additional species that occur on hummocks and tree bases include Toxicodendron radicans, Asplenium platyneuron, and moss species.
Comm #5292	Thuja plicata - Pseudotsuga menziesii - Abies grandis / Mahonia nervosa / Polystichum munitum Forest » more details accession code: VB.CC.37344.CEGL002848		0	This small-patch forest community occurs on gentle and middle slopes on all aspects within the Georgia Basin of British Columbia and adjacent Washington. These sites occur at elevations from 0 to 190 m. This plant community is characterized by a closed canopy of mixed conifers and a moderate shrub layer dominated by <i>Mahonia nervosa</i> and/or <i>Gaultheria shallon</i>, herb layer dominated by <i>Polystichum munitum</i>, and moss layer dominated by feathermosses. <i>Thuja plicata, Pseudotsuga menziesii</i>, and <i>Abies grandis</i> are usually present with high cover and typically codominate the overstory. The moderately well-developed shrub layer consists primarily of moderate cover of <i>Mahonia nervosa</i> and <i>Gaultheria shallon</i> together with low cover of <i>Rosa gymnocarpa</i> and <i>Vaccinium parvifolium</i>. <i>Polystichum munitum</i>, and often <i>Achlys triphylla</i> in British Columbia, dominate the moderately well-developed herb layer often with low cover of <i>Trientalis borealis, Rubus ursinus, Galium triflorum, Festuca subulata</i>, and <i>Trillium ovatum</i>. The moderately well-developed moss layer is dominated by high cover of <i>Eurhynchium oreganum</i> usually with low cover of <i>Leucolepis acanthoneuron</i> and <i>Hylocomium splendens</i>. It is distinguished from the similar but more species-poor ~<i>Pseudotsuga menziesii - (Abies grandis, Thuja plicata) / Mahonia nervosa - Gaultheria shallon</i> Forest (CEGL002845)$$ by high cover of rich-site indicator <i>Polystichum munitum</i> and other species such as <i>Tiarella trifoliata, Trillium ovatum</i>, and the moss <i>Leucolepis acanthoneuron</i>. It is distinguished from the similar <i>Pseudotsuga menziesii - Tsuga heterophylla / Gaultheria shallon / Polystichum munitum</i> Forest (Chappell 2005), which occurs more commonly in more moist climates, by the relative paucity of <i>Tsuga heterophylla</i> in relation to <i>Thuja plicata</i> and <i>Abies grandis</i>.

Comm #5295	Sphaeralcea (coccinea, parvifolia) Herbaceous Vegetation » more details accession code: VB.CC.31836.CEGL005366	Western Ecology Working Group of...	0	This herbaceous association occurs in valleys in the Colorado Plateau. Sites are flat to gently sloping on stream terraces, grabens, and canyon and valley bottoms at 1197-1687 m elevation. There is moderate to high ground surface cover of bare soil and low to moderate cover of litter (1-50 %). Some stands have moderate cover of biological soil crusts (30-40%). Substrate is sandy soil derived from alluvium or eolian sand. Disturbance appears important in some stands; small mammal burrows are present on some sites. Presence of ruderal species indicates recent or past disturbance. The vegetation is characterized by an open to moderately dense, perennial herbaceous layer dominated by <i>Sphaeralcea coccinea</i> or <i>Sphaeralcea parvifolia</i> (less often) with 4-15% cover, often with <i>Achnatherum hymenoides</i> and/or <i>Sporobolus cryptandrus</i>. Scattered shrubs and dwarf-shrubs may be present such as <i>Atriplex canescens, Ephedra</i> spp., <i>Krascheninnikovia lanata</i>, and <i>Opuntia</i> spp. Other herbaceous species include <i>Cryptantha</i> spp., <i>Plantago patagonica, Pleuraphis jamesii, Oenothera pallida</i>, and <i>Rumex hymenosepalus</i>. Introduced annual species such as <i>Bromus tectorum</i> and <i>Salsola tragus</i> may be present.
Comm #5296	Batis maritima Ruderal Dwarf-shrubland » more details accession code: VB.CC.31674.CEGL005401	Western Ecology Working Group of...	0	This ruderal dwarf-shrubland is currently sampled from a single national historical park in Hawaii, and this description is based on occurrences there. Additional global information will be added as it becomes available. It is found on low, level sites on ocean beaches or in marshy areas. Vegetation covers nearly all the ground on most sites. <i>Batis maritima</i> makes up nearly all the herbaceous stratum in most stands. <i>Sesuvium portulacastrum</i> and <i>Paspalum vaginatum</i> are common, though not dominant. There are essentially no woody strata in this community.
Comm #5297	Sporobolus silveanus - Tridens strictus Herbaceous Vegetation » more details accession code: VB.CC.27202.SPOROBOLUSSILVE	Southeastern Ecology Working Gro...	0	This 'tallgrass' community is dominated by Sporobolus silveanus, with lesser amounts of Tridens strictus and Paspalum floridanum. Typically there is a distinct stratum of low-growing species including Dichanthelium linearifolium, Dichanthelium aciculare, Dichanthelium oligosanthes var. oligosanthes, Aira elegans, Eragrostis hirsuta, and Eragrostis capillaris. Areas which have been mowed or overgrazed may have Andropogon ternarius, Rudbeckia maxima, Marshallia caespitosa or scattered woody species such as Maclura pomifera or Juniperus virginiana var. virginiana. This community occurs on loamy, low pH upland soils classified as Alfisols. Low, circular mounds called mima or pimple mounds dot the otherwise flat to gently rolling landscape in the northeastern portion of the Blackland Prairie in eastern Texas.
Comm #5298	Quercus macrocarpa - Quercus (alba, ellipsoidalis, velutina) Woodland Alliance » more details accession code: VB.CC.18661.QUERCUSMACROCAR	Midwestern Ecology Working Group...	0	This alliance, found in the Midwest, occurs on wet-mesic to dry-mesic sites. Stands in this alliance can have a canopy ranging from moderately open to moderately closed, approximately 25-80%. There is often a moderate shrub canopy (30-50%) layer 1-2 m tall but this can be absent. Quercus macrocarpa is the dominant tree in nearly all stands in this alliance. It can also be prominent in the shrub layer. Celtis occidentalis and Quercus bicolor are common trees in wet-mesic stands, along with smaller amounts of Platanus occidentalis and Ulmus americana, while Quercus alba, Quercus muehlenbergii, Quercus rubra, and Quercus velutina are often found in mesic to dry-mesic stands. In the shrub layer, Corylus americana is the most abundant. It is often accompanied by Ceanothus herbaceus, Cornus foemina, Euonymus atropurpurea, and Prunus spp. The herbaceous layer contains species such as Andropogon gerardii, Carex pensylvanica, Elymus virginicus, Laportea canadensis, and Sorghastrum nutans. This alliance occurs in wet-mesic, mesic, and dry-mesic moisture regimes. The environmental conditions vary substantially with the moisture regime. Wet-mesic communities are typically found on terraces near rivers and streams. Mesic and dry communities are found on flat, rolling, or hilly topography. All communities are most often found on silt and loam soils, and upland communities are also found on coarse-grained soils. Fire is an important factor in maintaining the relatively open structure of upland stands in this alliance.
Comm #5299	Thuja plicata - Pseudotsuga menziesii - Tsuga heterophylla / Polystichum munitum - Dryopteris expansa Forest » more details accession code: VB.CC.37343.CEGL002849		0	This small-patch forest community occurs on rich, mesic or subhygric sites in coastal British Columbia at elevations from 0 to 650 m. The range of this plant community occurs at lower elevations on coastal British Columbia and north to Hardwicke Island, in lower elevation drainages of the Fraser River near Chilliwack, and in the eastern Coast Mountains. This plant community is characterized by a closed canopy with mixed conifers and a moderate shrub layer dominated by <i>Acer circinatum</i>, moderate herb layer dominated by <i>Polystichum munitum</i>, and sparse moss layer dominated by feathermosses with some leafy mosses. Overstories are closed and dominated by high cover of <i>Thuja plicata, Tsuga heterophylla</i>, and <i>Pseudotsuga menziesii</i>. The moderately well-developed shrub layer is dominated by moderate cover of <i>Acer circinatum</i> and low cover of <i>Vaccinium parvifolium</i> and regenerating <i>Thuja plicata</i> and <i>Tsuga heterophylla</i>. The moderately well-developed herb layer is dominated by low to moderate cover of <i>Polystichum munitum</i> with low cover of <i>Dryopteris expansa, Tiarella trifoliata, Rubus ursinus</i>, and <i>Pteridium aquilinum</i>. The moss layer can be sparse to moderately well-developed, with <i>Hylocomium splendens</i> and <i>Eurhynchium oreganum</i> as predominant species along with low cover of <i>Rhytidiadelphus loreus</i> and <i>Plagiomnium insigne</i>. This association is distinguished from the wetter <i>Tsuga heterophylla - Pseudotsuga menziesii - Thuja plicata / Polystichum munitum - Athyrium filix-femina</i> Forest (not in USNVC) by the high constancy of <i>Acer circinatum</i> and the lack of seepage indicator species such as <i>Rubus spectabilis</i> and <i>Athyrium filix-femina</i>.
Comm #5300	Dasiphora fruticosa ssp. floribunda / Rhynchospora capillacea - Scleria verticillata Shrub Herbaceous Vegetation » more details accession code: VB.CC.27186.DASIPHORAFRUTIC	Eastern Ecology Working Group of...	0	This fen vegetation occurs in seepage areas of marl deposits along the shores of calcareous lakes in New Jersey, New York, and perhaps elsewhere. Saturated, calcium-rich marl deposits support stunted vegetation that is often sparse. The dominant species are graminoids, including Carex flava, Eleocharis rostellata, Cladium mariscoides, and Rhynchospora capillacea. Additional species present include Scleria verticillata, Lycopus uniflorus, Parnassia glauca, Sarracenia purpurea, Schoenoplectus acutus (= Scirpus acutus), Oligoneuron ohioense (= Solidago ohioensis), Triglochin palustris, Juncus articulatus, Lobelia kalmii, Carex crawei, Panicum flexile, Equisetum variegatum, Utricularia minor, and Carex eburnea. Shrubs may occur sporadically and can include Dasiphora fruticosa ssp. floribunda (= Potentilla fruticosa), Juniperus horizontalis, and Thuja occidentalis. Nonvascular species can include Campylium stellatum and, in pools or along streambanks, Chara vulgaris.
