P. 2011. Classifica...	0	This association occurs on open granitic domes (exfoliated outcrops of granite or gneiss) with shallow saturated soils, occurring where a small stream flows over the rock. It may also occasionally occur as narrow bands along streams flowing over exfoliated or dipslope surfaces on forested mountainsides. The flora is quite variable among examples but shares the characteristics of having an unusual mix that includes some species of Coastal Plain affinities or otherwise unusual for the region, mountain wetland species, some species characteristic of bogs, and usually some species of rock outcrops. The species occurring with the highest constancy in known examples are <i>Oxypolis rigidior, Drosera rotundifolia</i>, and <i>Rhynchospora</i> spp. Some wetland orchid species, e.g., <i>Platanthera clavellata, Calopogon</i> sp., <i>Pogonia ophioglossoides</i>, or others, are almost always present. <i>Sarracenia rubra ssp. jonesii (= Sarracenia jonesii)</i> or <i>Sarracenia purpurea</i> are sometimes abundant. <i>Osmunda cinnamomea</i> or <i>Osmunda regalis</i> are often abundant.
Comm #7306	Alnus oblongifolia / Baccharis salicifolia Forest » more details accession code: VB.CC.28042.ALNUSOBLONGIFOL	Western Ecology Working Group of...	0	This association is found along Palomas Creek and probably elsewhere in the Black Range (Sierra County) and the mountains of southwestern New Mexico and southeastern Arizona. Stands are known to occur along moderate-gradient (1.0-1.5%), lower montane stream channels at around 1525 m (5000 feet) elevation. Flooding is probably frequent, at least within a five-year return interval. Soils are cobbly and have been identified as moist sandy-skeletal Aeric Fluvaquents. This type is characterized by young, open stands of Alnus oblongifolia poles and saplings, with abundant Baccharis salicifolia in the shrub layer. Young Juglans major may also occur. Among the forbs, Apocynum cannabinum is well-represented, and the vines Vitis arizonica, Clematis ligusticifolia, and introduced Parthenocissus quinquefolia are common to well-represented.
Comm #7307	Physocarpus opulifolius - Alnus serrulata / Osmunda regalis - Parnassia grandifolia - Eryngium integrifolium Shrubland » more details accession code: VB.CC.37547.CEGL007048	Govus, T. 2011. Documentation of...	0	This shrub-dominated seepage vegetation is apparently restricted to the northern Georgia Blue Ridge and is associated with a ring of ultramafic geology that surrounds Brasstown Bald. A similar type of vegetation occurs on Bluff Mountain in North Carolina. This community has a somewhat mixed physiognomy ranging from shrub thicket with small scattered patches of open herbaceous vegetation. In general it occurs as a saturated shrubland dominated by <i>Physocarpus opulifolius, Alnus serrulata, Photinia pyrifolia (= Aronia arbutifolia), Acer rubrum var. trilobum</i>, and <i>Hypericum prolificum</i>. The herbaceous layer is relatively patchy but is quite diverse. Herbaceous species include <i>Osmunda regalis, Oxypolis rigidior, Parnassia grandifolia, Calopogon tuberosus, Andropogon glomeratus, </i><i>Pycnanthemum virginianum</i><i>, Schizachyrium scoparium, Xyris torta, Viola cucullata, Rhynchospora capitellata, Thelypteris palustris, Fuirena squarrosa, Rudbeckia fulgida, Solidago patula, Trautvetteria caroliniensis, Vernonia noveboracensis</i> and <i>Aristida longispica</i>.
Comm #7308	Alnus serrulata Saturated Southern Interior Shrubland » more details accession code: VB.CC.34733.CEGL007059	Southeastern Ecology Working Gro...	0	This association represents saturated shrub vegetation dominated by <i>Alnus serrulata</i> from the Interior Low Plateau and Upper East Gulf Coastal Plain ecoregions of the southeastern United States. This association occurs as stands adjacent to streamside or hillside herbaceous seepages, or as shrub-dominated inclusions in various types of saturated forest. It also may be found as small patches in wetlands which are influenced by beaver activity. These sites may occur on the edges of floodplains along low-gradient streams. Hydrology of some sites may also be influenced or enhanced by roads and other human construction. In the Western Highland Rim of Tennessee, small-scale saturated areas dominated by <i>Alnus serrulata</i> may form at the margins of seepage areas otherwise dominated by herbaceous plants, which are classified as ~<i>Carex lurida - Carex leptalea - Parnassia grandifolia - Juncus brachycephalus - (Xyris tennesseensis)</i> Herbaceous Vegetation (CEGL004161)$$. Saturated vegetation dominated by <i>Alnus serrulata</i> at Fort Benning, Georgia (East Gulf Coastal Plain - Upper East Gulf Coastal Plain transition region), on the upper ends of beaver ponds, is placed here, at least until another specific association is developed if necessary. These are shrub-dominated inclusions in a <i>Nyssa biflora</i> saturated forest.

Comm #7310	Pinus palustris Planted Forest » more details accession code: VB.CC.35580.CEGL007176	Southeastern Ecology Working Gro...	0	This association includes young, monospecific plantation stands of <i>Pinus palustris</i> that are maintained for the extraction of forest products. The core concept of these stands are those which are mechanically planted to dense, often perfect rows of planted <i>Pinus palustris</i> or otherwise dense, young stands which are managed and maintained for the extraction of forest products. Stands are typically established with mechanical planting, but may also be established through other means. In most cases these stands support almost no other tree species in the overstory, and typically very little understory. This association rarely exceeds 20-40 years of age on most timberlands. In North and South Carolina, pinestraw is commonly harvested from these forests. This association does not include natural or near-natural <i>Pinus palustris</i> forests that retain some natural ground layer components and that will be managed for restoration of a natural longleaf pine community even though the <i>Pinus palustris</i> may have been planted.
