Comm #5351	A.731 » more details accession code: VB.CC.2364.A731 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This alliance consists of non-tidal shrublands dominated by ~Rhizophora mangle$. ~Rhizophora mangle$ is generally the monodominant shrub, and characteristically forms an open to even scattered shrub stratum, in contrast to most tidal ~Rhizophora mangle$ communities. Various herbs, such as ~Eleocharis cellulosa$, with ~Utricularia purpurea, Utricularia$ spp., ~Rhynchospora tracyi, Crinum americanum$, and the macro-alga ~Chara$ sp., may be common. This alliance occupies more highly stressed sites than the I.A.5.N.f ~~Rhizophora mangle$ Tidal Forest Alliance (A.83)$$ and has shorter individual trees (less than 5 m and usually only 0.5-2 m tall).

The natural...	0	This vegetation occurs in seasonally flooded upland ponds in the Ridge and Valley and adjacent Cumberland Plateau of Alabama and Georgia (and possibly Tennessee). Vegetation is zoned with an outer ring of trees, a series of interior zones of shrubs, herbs and vines, and a central area with or without standing water year round depending on precipitation. Tree species include <i>Nyssa biflora</i> (which is most abundant and diagnostic), <i>Liquidambar styraciflua</i>, and <i>Acer rubrum var. rubrum</i> (which are present but not diagnostic). There are two shrub zones, one dominated by <i>Cephalanthus occidentalis</i> and another slightly higher one dominated by <i>Lyonia lucida</i>. The greenbrier <i>Smilax laurifolia</i> is also present. Herbaceous dominants include <i>Woodwardia virginica</i> and <i>Osmunda regalis var. spectabilis</i> in a fern zone, with <i>Carex glaucescens, Dulichium arundinaceum</i>, and <i>Panicum virgatum (= var. cubense)</i> in a grass-sedge zone. A deeper open-water zone contains <i>Torreyochloa pallida (= Glyceria pallida), Potamogeton pulcher</i>, and <i>Utricularia gibba (= Utricularia biflora)</i>. Many plants found in this habitat are otherwise restricted to the Coastal Plain, at least in Georgia.
Comm #5357	Schoenoplectus pungens - Fimbristylis (castanea, caroliniana) Herbaceous Vegetation » more details accession code: VB.CC.31234.CEGL004117	Eastern Ecology Working Group of...	0	This interdunal swale community of the Eastern Shore of Virginia and Maryland is characterized by dense cover of <i>Schoenoplectus pungens (= Scirpus pungens)</i> and/or <i>Spartina patens</i>, with <i>Fimbristylis castanea</i> or <i>Fimbristylis caroliniana</i>. There is usually shallow standing water present in these swales in the spring, when <i>Schoenoplectus pungens</i> or <i>Spartina patens</i> is generally dominant with few other associates except species of <i>Eleocharis</i>. By late summer a number of other species such as <i>Fimbristylis castanea</i> and <i>Sabatia stellaris</i> contribute more substantial cover. Other herbs contribute very little to the overall vegetative cover. These associated species include <i>Andropogon virginicus, </i><i>Andropogon glomeratus, </i><i>Eleocharis rostellata, Phragmites australis, Pluchea foetida, </i><i>Pluchea odorata, Cyperus filicinus, </i><i>Juncus scirpoides, Hydrocotyle umbellata, Eleocharis parvula, Panicum amarum, Fimbristylis autumnalis, Sabatia stellaris, Ptilimnium capillaceum, Fuirena pumila</i>, and <i>Juncus canadensis</i>. Diagnostic species are <i>Schoenoplectus pungens</i> and <i>Fimbristylis castanea</i>. Related vegetation of the Atlantic coast from North Carolina southward is accommodated under ~<i>Fimbristylis castanea - Schoenoplectus pungens</i> Seasonally Flooded Herbaceous Vegetation (CEGL003790)$$.
Comm #5358	Picea engelmannii / Calamagrostis canadensis Forest » more details accession code: VB.CC.26772.PICEAENGELMANNI	Western Ecology Working Group of...	0	This forest plant association occurs on cool, moist sites at low to high elevations in the Rocky Mountains of Montana, Wyoming, and southeastern Idaho. It is generally restricted to flat to gently sloping sites with poor drainage, such as fen and lake margins, toeslopes, and low stream and river terraces. This community usually is saturated for a good portion of the year, and stands have a high water table year round. The ground surface in these stands is characterized by a large amount of microtopography stemming from wind-thrown trees. The overstory is dominated by Picea engelmannii or Picea engelmannii X glauca hybrids, and Abies lasiocarpa may also be present. Not infrequently Pinus contorta is a long-persisting seral component. Shrub canopy coverage is low, although the diversity of shrub species present is fairly high. Calamagrostis canadensis and Calamagrostis stricta are diagnostic species when well-represented; usually under these shaded forest conditions Calamagrostis canadensis dominates the ground layer, often forming what appears to be a pure grass sward.

Abundant species are Diodia teres, Croton willdenowii, Sporobolus vaginiflorus var. ozarkanus (= Sporobolus ozarkanus), and Talinum spp. Characteristic species include Isanthus brachiatus (= Trichostema brachiatum), Sporobolus clandestinus, Sporobolus vaginiflorus var. ozarkanus, Portulaca smallii, Polygonum tenue, Symphyotrichum parviceps (= Aster parviceps), Talinum teretifolium, Talinum mengesii?, Ruellia humilis, Cyperus granitophilus, Bulbostylis capillaris, Commelina erecta var. erecta, and Manfreda virginica. Some additional herbs include Packera anonyma, Matelea decipiens, Lithospermum canescens, Piptochaetium avenaceum, Erigeron strigosus, Schizachyrium scoparium, Blephilia ciliata, and Sisyrinchium sp. Wetter areas have Zephyranthes atamasca. Some shrubs which are present on the margins include Symphoricarpos orbiculatus, Rhus aromatica, Ulmus alata, Celtis tenuifolia, Viburnum rafinesquianum, Hypericum hypericoides, and Vitis rotundifolia.
Comm #5360	Halodule beaudettei Permanently Flooded - Tidal Herbaceous Alliance » more details accession code: VB.CC.26263.HALODULEBEAUDET	Southeastern Ecology Working Gro...	0	This alliance occurs in tropical and warm-temperate estuarine waters. Halodule beaudettei (= Halodule wrightii) may be monodominant or may occur in admixtures with other seagrass species. This alliance can occur in shallower waters than other seagrass alliances, since Halodule beaudettei tolerates exposure to the atmosphere at low tide. Following bottom disturbance, Halodule beaudettei is usually the first colonizer, and in some situations later succeeds to other seagrass communities. This alliance is widespread in waters of Florida and Texas, and present in lesser amounts in other states. About 80,000 hectares are dominated by Halodule in Core and Pamlico sounds in North Carolina, where Halodule occurs substantially disjunct from the main body of its distribution farther south. It also occurs in inlets on the eastern coast of Florida. Halodule beaudettei is the most common seagrass found along the Gulf Coast of Texas and is often found occurring with minor amounts of the shorter stature Halophila engelmannii and the annual Ruppia maritima.
