Avicennia germinans / Sarcocornia pacifica Shrubland

This association comprises mangrove communities growing on exposures of Miami Formation oolite in the Lower Florida Keys. It is dominated by a rather sparse stratum of <i>Avicennia germinans</i> (20-60% cover), mostly rooting in solution cavities, stunted by lack of soil and hypersaline conditions. Rarely <i>Laguncularia racemosa</i> may be present. <i>Salicornia virginica</i> is scattered. No herbs are normally present. Oceanwards this community normally adjoins a deeper water <i>Rhizophora mangle</i> community. Landwards this community grades into a shrubless <i>Monanthochloe littoralis</i> community, which then grades into a <i>Conocarpus erectus</i> community. |

Stands of this forest are dominated by <i>Taxodium distichum, Nyssa biflora, Acer rubrum</i>, and <i>Magnolia virginiana</i>. It is known in Florida from Big Gum Swamp Wilderness, Osceola National Forest and farther east at Timucuan Ecological and Historic Preserve and may also occur directly to the north at Pinhook Swamp, Osceola National Forest and Okefenokee Swamp National Wildlife Refuge. There it occurs in a large, poorly drained flat area, with some poorly defined creeks which are tributaries of the Middle Fork St. Mary's River. The site is along the flat divide between the Atlantic drainage (St. Mary's River) and Gulf drainage (Suwannee River)At Timucuan it occurs along the Thomas Creek tributary of the Nassau River. This forest is dominated by <i>Taxodium distichum, Nyssa biflora, Acer rubrum</i>, and <i>Magnolia virginiana</i>. The subcanopy is composed of <i>Acer rubrum, Magnolia virginiana</i>, and <i>Persea palustris</i>. Shrubs are <i>Lyonia lucida, Morella cerifera, Persea palustris</i>, and <i>Leucothoe racemosa</i>. <i>Toxicodendron radicans</i> is an important vine, and <i>Dulichium arundinaceum</i> is the only sparse herb documented. In a stand from the Ocala National Forest, the canopy contains <i>Nyssa biflora, Taxodium distichum, Acer rubrum</i>, and <i>Pinus elliottii</i>. In addition, the subcanopy contains <i>Ulmus americana (= var. floridana), Ilex cassine, Persea palustris</i>, and <i>Sabal palmetto</i>. Shrubs include <i>Diospyros virginiana, Fraxinus caroliniana, Ilex cassine, Itea virginica, Morella cerifera, Nyssa biflora, Persea palustris, Quercus nigra, Toxicodendron radicans</i>, and <i>Vaccinium virgatum</i>. Vines include <i>Parthenocissus quinquefolia, Smilax bona-nox, Decumaria barbara</i>, and <i>Vitis aestivalis</i>. Herbs include <i>Woodwardia virginica, Hypoxis curtissii, Peltandra virginica, Dichanthelium</i> sp., <i>Osmunda regalis, Carex</i> sp., <i>Chasmanthium nitidum, Mitchella repens, Osmunda cinnamomea, Solidago latissimifolia</i>, and the epiphytic <i>Tillandsia bartramii</i>. |

Potamogeton spp. - Ceratophyllum demersum Great Plains Herbaceous Vegetation

accession code: VB.CC.18336.POTAMOGETONSPPC

Midwestern Ecology Working Group... |

This community type is found in the Great Plains of the United States in shallow to relatively deep (1 m) freshwater basins or bands in marshes or bays that remain flooded in all but the driest years. Vegetation varies from sparse to dense, with submersed rooted and free-floating macrophytes. Species composition varies with substrate, water depth, water chemistry, turbidity, water temperatures and other factors, but these are poorly understood. Dominant species in Nebraska include narrow-leaved pondweeds (Potamogeton foliosus, Stuckenia pectinata (= Potamogeton pectinatus), Potamogeton pusillus), Najas guadalupensis, and Zannichellia palustris. Ceratophyllum demersum and Utricularia macrorhiza can be locally abundant. In quiet bays, Potamogeton nodosus and Lemna spp. are common. In clear water with sandy bottoms Chara spp. may also be common. |

This association represents longleaf pine flatwoods dominated by <i>Pinus palustris, Quercus minima, Quercus pumila</i>, and <i>Aristida beyrichiana</i>. Some shrubs present in stands are <i>Serenoa repens, Vaccinium myrsinites, Ilex glabra, Asimina angustifolia (= Asimina longifolia), Vaccinium stamineum, Vaccinium darrowii</i>, and <i>Ceanothus microphyllus</i>. The herbaceous flora can be very diverse, dominated by <i>Aristida beyrichiana</i> with <i>Sericocarpus tortifolius (= Aster tortifolius), Liatris</i> spp., <i>Pteridium aquilinum, Eriogonum tomentosum, Carphephorus odoratissimus, Sporobolus floridanus, Sorghastrum secundum, Pityopsis aspera var. adenolepis (= Pityopsis adenolepis), Andropogon</i> spp., and <i>Baptisia simplicifolia</i>. |

This association has only been described from Canyon de Chelly and Dinosaur national monuments, but it is likely to occur on abandoned floodplain terraces of low-gradient rivers and streams throughout the eastern Colorado Plateau of Colorado, Utah, New Mexico and northeastern Arizona. The association is best developed on level valley bottom sites that no longer flood and that have been subjected to a long history of domestic livestock grazing. The vegetation underneath the open gallery canopy of <i>Populus deltoides ssp. wislizeni</i> consists primarily of upland plants and is dominated by aggressive exotic species such as <i>Bromus tectorum, Elymus repens, Acroptilon repens, Lepidium latifolium</i>, and <i>Poa pratensis</i>. Relict native grasses, shrubs and forbs may be present with relatively low cover. |

This association represents a "coastal strand" community dominated by <i>Serenoa repens</i> and <i>Ilex vomitoria</i>. This type ranges from Volusia County, Florida, to southern Georgia. Other characteristic species include <i>Sabal palmetto</i> and <i>Sideroxylon tenax</i>. It differs from coastal strand vegetation to the south in its characteristic codominance of <i>Ilex vomitoria</i> and the rarity or absence of more southern (subtropical) floristic elements such as <i>Coccoloba uvifera, Myrsine floridana, Forestiera segregata</i>, and <i>Myrcianthes fragrans</i>. The presence of <i>Sideroxylon tenax</i> and <i>Serenoa repens</i> and the absence of vines differentiate it from the dune "shrub/vine" thickets on barrier islands of North and South Carolina, i.e., ~<i>Smilax auriculata - Toxicodendron radicans</i> Vine-Shrubland (CEGL003885)$$. |
