Comm #13061	A.963 » more details accession code: VB.CC.2590.A963 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	Vegetation types within this alliance occur in dry areas in the lower alpine and upper subalpine habitats. They occupy a narrow belt immediately above timberline with a range of elevation from 2590-3810 m. Landforms can include dry, rocky slopes to mesic meadows, typically of early-melting snowpatches. The plant associations within this alliance are specific to well-drained, mineral soils of mesic environments. They occur primarily on protected, low slopes of moderately inclined (20-45%), non-southerly exposed terrain. Sites representing these associations are found on alluvial and colluvial parent materials of granitic, gneiss, and schist origins. The soils originating from these parent materials are Inceptisols. Communities within this alliance are characterized as cold-deciduous, temporarily flooded shrublands. The short-shrub layer is dominated by ~Salix glauca$ with 60-100% cover. The graminoid layer is typically continuous with 25-60% cover and dominated by ~Deschampsia caespitosa$. Other graminoids can include ~Carex heteroneura var. chalciolepis, Festuca brachyphylla$, and ~Trisetum spicatum$. The forb layer is sparse (10-25% cover), consisting of ~Artemisia scopulorum, Castilleja occidentalis, Geum rossii$, and ~Polygonum bistortoides$. Adjacent upslope communities are typically subalpine fir/Engelmann spruce.
Comm #13062	A.677 » more details accession code: VB.CC.2312.A677 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This alliance includes woodland vegetation dominated by ~Pinus virginiana$, possibly with a mixture of ~Pinus rigida, Pinus pungens$, and/or ~Quercus prinus$. Associations in this alliance are possible from central Pennsylvania southwest to Virginia and Tennessee, but tend to occur under extreme conditions (such as steep, shaley slopes) that maintain the open structure of the vegetation.

Comm #13066	Picea mariana - Abies balsamea / Sibbaldiopsis tridentata Shrubland » more details accession code: VB.CC.31342.CEGL006038	Eastern Ecology Working Group of...	0	This shrubby alpine krummholz occurs at high elevations in the Northern Appalachians of the northeastern United States and adjacent Canada. The setting is high, wind-exposed alpine peaks and exposed high-elevation summits, usually from 1067-1494 m (3500-4900 feet) elevation. Soils are thin organic Histosols or peat. The stunted trees form matted, wind-pruned alpine conifer thickets, usually of 60-100% cover. Dwarf-shrubs and herbs are occasional in openings among the shrubby trees. Bryoids, also in the openings, are sparse; decomposing organic litter makes up the remainder of the ground cover. The krummholz is dominated by a variable mixture of <i>Picea mariana, Abies balsamea</i>, and <i>Betula papyrifera var. cordifolia</i>. Dwarf-shrubs and herbs include <i>Ledum groenlandicum, Vaccinium uliginosum, Empetrum nigrum, Vaccinium vitis-idaea, Clintonia borealis, Cornus canadensis, Sibbaldiopsis tridentata, Trientalis borealis, Gaultheria hispidula</i>, and <i>Solidago macrophylla</i>. This association shares many species with subalpine spruce-fir forests (e.g., ~<i>Abies balsamea - (Betula papyrifera var. cordifolia)</i> Forest (CEGL006112)$$), but the low stature and matted form of the trees is distinctive.
Comm #13067	Pinus rigida / Schizachyrium scoparium - Sorghastrum nutans - Baptisia tinctoria Woodland » more details accession code: VB.CC.35513.CEGL003617	Southeastern Ecology Working Gro...	0	This association includes dry woodlands of the Cumberlands of Kentucky and possibly Virginia on steep, south- to southwest-facing slopes. This community is known from the Kentucky side of Pine Mountain, in the Cumberland Mountains (on the Virginia-Kentucky stateline). It has a canopy strongly dominated by <i>Pinus rigida</i>, also with some <i>Pinus virginiana</i> (around rock outcrops) and scattered <i>Quercus prinus</i> and sometimes <i>Quercus marilandica</i>. Canopy coverage varies from 10-80%. Scattered shrubs are present. <i>Schizachyrium scoparium</i> and <i>Sorghastrum nutans</i> dominate the herb layer, and <i>Baptisia tinctoria</i> is also very abundant. This vegetation is fire-maintained, but also strongly influenced by dry conditions.
Comm #13068	Juniperus virginiana var. virginiana / Schizachyrium scoparium Ruderal Forest » more details accession code: VB.CC.36269.CEGL003628	Southeastern Ecology Working Gro...	0	Results from fire suppression in glades and grasslands. This community is found throughout Oklahoma, ranging into the West Gulf Coastal Plain of Texas and into the Interior Highlands of Arkansas and Missouri.

Comm #13070	Pinus palustris - (Pinus serotina) / Ilex glabra - Gaylussacia frondosa - (Kalmia carolina) Woodland » more details accession code: VB.CC.35575.CEGL003647	Southeastern Ecology Working Gro...	0	<i>Pinus palustris</i> (and sometimes <i>Pinus taeda</i> or <i>Pinus serotina</i>) dominates the open canopy of this Mid-Atlantic Coastal Plain flatwoods. The shrub layer is often dense, dominated by <i>Gaylussacia frondosa, Ilex glabra, Gaylussacia baccata, Clethra alnifolia, Morella cerifera (= Myrica cerifera), Gaylussacia dumosa (= var. dumosa), Lyonia mariana</i>, and <i>Arundinaria gigantea ssp. tecta</i>. Other characteristic species include <i>Vaccinium crassifolium, Pteridium aquilinum var. pseudocaudatum</i>, and <i>Pyxidanthera barbulata</i>. This community is poorly understood, since few examples remain, and these are in poor condition. These communities are moist to wet longleaf pine flatwoods north of the range of <i>Aristida stricta</i>.
