This community is a dense, tropical, broad-leaved, evergreen forest with an open understory, occurring on areas of elevated rock. Canopies are typically 9-12 m and composed of trees 10-20 cm in diameter with scattered individuals that are up to 100 cm in diameter. Common canopy species include Metopium toxiferum, Krugiodendron ferreum, Swietenia mahagoni, Guapira discolor, Bursera simaruba, Coccoloba diversifolia, Lysiloma latisiliquum, Sideroxylon salicifolium (= Bumelia salicifolia, = Dipholis salicifolia), Sideroxylon foetidissimum (= Mastichodendron foetidissimum), and Ficus aurea. Well-developed subcanopies contain smaller individuals of canopy species and Eugenia axillaris, Eugenia foetida, Gymnanthes lucida, Thrinax radiata, Thrinax morrisii, Amyris elemifera, Drypetes diversifolia, Canella winteriana, Bourreria succulenta (= Bourreria ovata), Sapindus saponaria, Guajacum sanctum, etc. Species that occur as shrubs include Psychotria nervosa, Ardisia escallonoides, Guettarda elliptica, Guettarda scabra, Colubrina elliptica, Capparis flexuosa, and Eugenia rhombea. Only a few shade-tolerant herbs are found beneath the dense forest cover (Dichanthelium dichotomum, Oplismenus hirtellus ssp. setarius (= Oplismenus setarius), Lasiacis divaricata). Scattered orchids (Eulophia alta, Beloglottis costaricensis (= Spiranthes costaricensis), Cyclopogon cranichoides (= Spiranthes cranichoides), Stenorrhynchos lanceolatum (= Spiranthes lanceolata), Eltroplectris calcarata) and clumps of ferns (Nephrolepis exaltata, Nephrolepis biserrata, Thelypteris kunthii) may grow in areas with sufficient moisture. Other ferns (Adiantum tenerum, Tectaria heracleifolia, Tectaria fimbriata, Thelypteris reptans, Thelypteris sclerophylla) grow on the walls of solution holes. Herbaceous epiphytes are abundant and conspicuous (Campyloneurum phyllitidis, Pleopeltis polypodioides ssp. polypodioides, Phlebodium aureum, Vittaria lineata, Tillandsia spp.). |

Vegetation included in this alliance occurs in wet meadows in the Washington Cascades. It was described near Findley Lake at 1130 m elevation. Stands are found on the margins of lakes and in small depressions. Other information is not available. This vegetation includes subalpine wet meadows from the Cascade Mountains of Washington. Stands have a dense herbaceous layer (100% cover) by perennial graminoid Elymus hirsutus and the perennial forb Caltha leptosepala ssp. howellii. Associates include Aconitum columbianum, Carex spp., Trisetum sp., Senecio triangularis, Sanguisorba canadensis (= Sanguisorba sitchensis), Dodecatheon jeffreyi, and several others. Small differences in microtopography result in large variation in species composition. |

Juniperus virginiana Alkaline Bluff Woodland

This red-cedar alkaline bluff woodland occurs in the Ozarks region of the United States. Stands may have been of minimal extent on blufftops of the White River region in southwestern Missouri. Soils are rapidly drained, very shallow (0-40 cm), and occur over cherty limestone or dolomite, or with bedrock partially exposed at the surface. The vegetation contains an open-tree canopy, sometimes clumped or irregular due to the exposed bedrock. A shrubby or viney layer may or may not be present. Along bluffs, the herbaceous layer is variable. Tree dominants include <i>Juniperus virginiana</i>, with occasional hardwoods such as <i>Quercus muehlenbergii</i> or <i>Fraxinus americana</i>. Ground layer dominants include <i>Schizachyrium scoparium, Sorghastrum nutans</i>, and <i>Bouteloua curtipendula</i>. |

This association occurs on slopes and uplands and is restricted in Oklahoma to Cimarron County. It presumably should occur in immediately adjacent northern Texas, southeastern Colorado, southwestern Kansas, and/or northeastern New Mexico. Associated species include Bothriochloa saccharoides, Bouteloua eriopoda, Eriogonum jamesii, Melampodium leucanthum, Opuntia imbricata, and Zinnia grandiflora. |

Pinus echinata - Quercus falcata East Gulf Coastal Plain Forest
» more details
accession code: VB.CC.34961.CEGL004052

This association is one of several documented types of shortleaf pine - hardwood forests in the Upper East Gulf Coastal Plain. Stands are dominated by <i>Pinus echinata</i>, often with a significant hardwood component. The most characteristic hardwood, often the second most important overstory tree, is <i>Quercus falcata</i> (although other tree species may also be encountered in stands of this type, they are generally lacking from the overstory or found only in limited abundance). A number of subcanopy, shrub, and herbaceous species may also be present; the specific floristic composition may vary among stands based on a number of factors. This type should be compared to other <i>Pinus echinata</i> communities of the region; stands with high cover values of white oak are generally accommodated by ~<i>Pinus echinata - Quercus alba - Carya alba</i> East Gulf Coastal Plain Forest (CEGL004050)$$. Stands of this association are subject to frequent prescribed burning on the Tombigbee National Forest (Mississippi), and many are managed for red-cockaded woodpecker (<i>Picoides borealis</i>) on the adjacent Noxubee National Wildlife Refuge. |
