This plant association is a minor type in south-central Alaska's rainforests. It occurs on floodplains and undisturbed north-aspect foot slopes with less than 15% slope and at less than 30 m (100 feet) elevation. Picea sitchensis is the dominant conifer with Tsuga heterophylla occasionally occurring as a minor associate. There are no shrub species dominant in this type, but Alnus viridis ssp. sinuata (= Alnus crispa ssp. sinuata), Oplopanax horridus (= Echinopanax horridus), Vaccinium ovalifolium, and Rubus spectabilis may be present. Lysichiton americanus is well represented in the undergrowth. Herbaceous species with high constancy but low cover include Rubus pedatus, Cornus canadensis, Tiarella trifoliata, Streptopus amplexifolius, Dryopteris expansa (= Dryopteris dilatata), Gymnocarpium dryopteris, and Phegopteris connectilis (= Thelypteris phegopteris). |

This coastal grassland community occurs in northeastern Florida, ranging from Volusia County, Florida, northwards into Georgia and South Carolina. In Florida, this community occurs "primarily on the broader barrier islands such as Amelia, Little Talbot, and Anastasia islands" (Johnson and Muller 1993), and "only on prograding coasts" (Johnson and Muller 1993b). The dominance of woody vines and forbs and relative rarity of grasses (<i>Uniola</i> only in 4 of 10 stands, <i>Spartina patens</i> in 2 of 10 stands in northeastern Florida) may separate these communities from related communities in the Carolinas. Other characteristic species recorded from Florida include <i>Triplasis purpurea, Sideroxylon tenax, Yucca gloriosa, Morella cerifera (= Myrica cerifera), Ipomoea imperati, Uniola paniculata, Spartina patens, Hydrocotyle bonariensis, Opuntia pusilla, Opuntia stricta</i>. This community differs from the less woody dune community in the same geographic area, the ~<i>Uniola paniculata - Hydrocotyle bonariensis</i> Herbaceous Vegetation (CEGL004040)$$. |

This maritime shrubland association represents a more southern version of ~<i>Quercus virginiana - (Ilex vomitoria)</i> Shrubland (CEGL003833)$$ found in the Southern Atlantic Coastal Plain and dominated by <i>Serenoa repens</i>. It is described from a single plot at Canaveral National Seashore, and thus, its status is provisional until additional data are acquired. |

This alliance consists of moderate- to high-elevation rocky summit communities of the southern and central Blue Ridge (metamorphic rock portions of the southern and central Appalachians), on various rock types, including amphibolite, metabasalt (greenstone), gneiss, and others. There are several globally rare communities contained in this alliance. More common vegetation in this alliance will have ~Saxifraga michauxii$ as a characteristic component; other species are variable, but may include ~Saxifraga virginiensis, Saxifraga micranthidifolia, Carex$ spp., ~Schizachyrium scoparium$, and others. Examples at high elevation exhibit a sparse vegetative cover of grasses, forbs and shrubs rooted in rock fissures and occur in a matrix of ~Picea rubens - Abies fraseri$ Forest. On rock outcrops of highly fractured felsic to mafic bedrock (over 1980 m), typical species include ~Carex misera, Abies fraseri, Menziesia pilosa, Heuchera villosa, Rhododendron catawbiense, Saxifraga michauxii, Sorbus americana, Oclemena acuminata (= Aster acuminatus), Solidago glomerata$. Other characteristic species are ~Minuartia groenlandica$ and ~Polypodium appalachianum$. On rock outcrops of felsic Anakeesta slate in the Great Smoky Mountains (from 1646-1987 m), typical species include ~Saxifraga michauxii, Carex misera, Calamagrostis cainii, Rhododendron carolinianum, Solidago glomerata, Oclemena acuminata, Abies fraseri$, and ~Leiophyllum buxifolium$. Other characteristic species are ~Gentiana linearis$ and ~Calamagrostis cainii$. At low to middle elevations (1256-1713 m) in the southern Appalachians on outcrops of mafic rock, or on felsic rock where perennial seepage exists, the sparse vegetation consists of graminoids, forbs, and shrubs. It is surrounded by deciduous forests dominated by ~Quercus rubra, Acer rubrum var. rubrum$, and occasionally ~Tsuga caroliniana$. Typical species here include ~Saxifraga michauxii, Coreopsis major, Schizachyrium scoparium, Kalmia latifolia, Dichanthelium acuminatum, Danthonia spicata$, and ~Paronychia argyrocoma$. Other characteristic species include ~Campanula divaricata, Solidago bicolor$, and ~Allium cernuum (= Allium allegheniense)$. On amphibolite, metabasalt, metagabbro, or metagraywacke bedrock from 1350-1870 m elevation within a matrix of ~Quercus rubra$ Forest or high elevation grasslands and shrublands, the vegetation includes ~Saxifraga michauxii, Danthonia spicata, Krigia montana, Carex misera, Angelica triquinata, Athyrium filix-femina ssp. asplenioides, Rhododendron catawbiense$, and ~Heuchera villosa$. Other characteristic species are ~Sanguisorba canadensis, Sibbaldiopsis tridentata, Hylotelephium telephioides (= Sedum telephioides), Houstonia purpurea var. montana, Geum radiatum, Solidago spithamaea$, and ~Huperzia appalachiana$. In the central Blue Ridge mountains of Virginia, at elevations of 850-1200 m, this alliance occurs on greenstone (metabasalt, a mafic metamorphic rock). Characteristic herbaceous species include ~Hylotelephium telephioides, Solidago simplex var. randii, Heuchera pubescens, Deschampsia flexuosa, Houstonia longifolia (= Houstonia longifolia var. compacta), Dennstaedtia punctilobula, Campanula divaricata, Agrostis perennans, Carex pensylvanica, Saxifraga michauxii, Arabis lyrata, Allium allegheniense?, Phlox subulata ssp. brittonii, Sibbaldiopsis tridentata, Liatris turgida, Huperzia appalachiana, Polypodium appalachianum, Gymnocarpium appalachianum$, and ~Oclemena acuminata$. Shrubs include ~Physocarpus opulifolius, Sorbus americana, Betula alleghaniensis, Quercus rubra, Ribes rotundifolium, Diervilla lonicera, Hamamelis virginiana, Ilex montana, Kalmia latifolia, Menziesia pilosa$, and ~Abies balsamea$. Rare alpine disjunct species are sometimes present, including ~Juncus trifidus$ and ~Trisetum spicatum$. |

Large areas dominated by algae in southern Florida and the West Indies. This community is a seasonally flooded wetland over oolitic limestone, which develops an oozy marl surface which has an algal periphyton (100% cover) with embedded and emergent Chara spp., and sometimes also a very sparse growth of Utricularia spp. and/or Eleocharis spp. Vascular plants are absent apparently because of extremely harsh chemistry (physiologically it is probably very difficult for a plant to access any cation other than Ca2+, which swamps out all other cations), and competition with the dominant algae. Individual occurrences can cover hundreds or thousands of acres, and on North Andros Island in the Bahamas this community probably makes up about 100 square miles out of the total 1000-square-mile island. |

This scrub aspen - oak community type occurs in the upper midwestern United States in the pine barrens region of Wisconsin. Stands occur on sandy, somewhat acid soils. Frequent fires reduce the woody vegetation to a scrub layer. The vegetation is comprised of a scrubby, fire-tolerant woody layer between 1 and 3 m tall, with a rich herbaceous layer. The scrub or brush layer contains Quercus macrocarpa, Quercus ellipsoidalis and Populus tremuloides. Various shrub species may also occur, including Corylus americana, Gaylussacia baccata, Rosa spp., Vaccinium angustifolium, and Salix spp. The herbaceous layer resembles that of open pine barrens, with species such as Comptonia peregrina, Gaultheria procumbens, Pteridium aquilinum, and other prairie forbs present. |
