Element Concept

Global Summary: Talus slopes varying from very sparse to sometimes with substantial cover of Toxicodendron radicans and Parthenocissus quinquefolia, and with scattered herbs including Dicentra eximia, Dryopteris marginalis, Polymnia canadensis, and Dioscorea quaternata. Known from low elevations (below 2500 feet) in the Appalachians (e.g., Nantahala Gorge, North Carolina, and Neddy Mountain, Tennessee).

Global Environment: Known from talus slopes at low elevations (below 2500 feet) in the Appalachians (e.g., Nantahala Gorge, North Carolina, and Neddy Mountain, Tennessee).

Vegetation Description

Global Vegetation: Stands of this vegetation vary from very sparse to sometimes with substantial cover of Toxicodendron radicans and Parthenocissus quinquefolia, and with scattered herbs including Dicentra eximia, Dryopteris marginalis, Dioscorea quaternata. An (apparent) example of this vegetation in the Cherokee National Forest, Tennessee (Neddy Mountain #1) has coverage by Toxicodendron radicans, Parthenocissus quinquefolia, Dryopteris marginalis, Polymnia canadensis, Vitis rotundifolia, and foliose lichens.

Conservation Status Rank

Global Rank & Reasons: G2G3Q (14-Dec-1998). This community is of uncertain circumscription. Its global rank is dependent on its circumscription. As defined, it is definitely known to occur in North Carolina, and a stand attributed to this type has been found in Tennessee. It may also be found in other Appalachian states. It is unlikely to be common, since unforested talus slopes are limited in this region.

VII.C.1.N.b. Dunes with sparse woody vegetation

A.1858 Vitis rotundifolia - Parthenocissus quinquefolia / Triplasis purpurea Unstabilized Dune Sparsely Vegetated Alliance


Muscadine - Virginia Creeper / Purple Sandgrass Unstabilized Dune Sparsely Vegetated Alliance

Alliance Concept

Summary: This alliance consists of very sparsely vegetated large shifting coastal dunes (meda). The vegetation consists primarily of woody vines which reached the canopy of maritime forests now covered by the shifting (rogue) dunes. As the forest was covered by the shifting dune, woody vines were able to grow rapidly enough to avoid being covered, and now form low mounds on the surface of the dune which accumulate wind-blown sand. Scattered vegetation is present, particularly woody vines. Vitis rotundifolia, Parthenocissus quinquefolia, Campsis radicans, and Vitis cinerea var. floridana are particularly prevalent. Scattered clumps of pioneer herbs and subshrubs, such as Uniola paniculata and Hudsonia tomentosa occur in sheltered locations, particularly low on the dune.

Common Name:



Ecological System(s): Atlantic Coastal Plain Northern Dune and Maritime Grassland (CES203.264)

Status: Standard Circumscription Confidence: 1 - Strong

Concept Author(s): A.S. Weakley

Element Concept

Global Summary: This association consists of large, shifting dunes (meda15-50 m high in the Mid-Atlantic Coastal Plain of North Carolina. Scattered vegetation is present, particularly woody vines, such as Vitis rotundifolia, Vitis cinerea var. floridana, Campsis radicans, and Parthenocissus quinquefolia. Scattered clumps of pioneer herbs, shrubs, and subshrubs, such as Schizachyrium littorale (= Schizachyrium scoparium ssp. littorale), Panicum amarum, Ammophila breviligulata, Triplasis purpurea, Uniola paniculata, Cenchrus tribuloides, Diodia teres, Chrysopsis gossypina, Prunus serotina, and Hudsonia tomentosa occur in sheltered locations, particularly low on the dune. This community apparently harbors several globally rare invertebrates. Dunes with any substantial vegetation are not classified here. The best remaining examples of this sparse vegetation are Jockey's Ridge and Run Hill (Dare County, North Carolina). Former examples (now stabilized and vegetated) are the Seven Sisters (Currituck County, North Carolina), Kitty Hawk (Dare County, North Carolina), and Bald Head (Brunswick County, North Carolina). These are the highest dunes on the coast of eastern North America.

Global Rank & Reasons: G1 (31-Dec-1997). This community is much rarer now than in former times (though it was always rare), owing to human attempts (largely successful) to stabilize coastal vegetation (especially "rogue dunes").

VII.C.2.N.a. Sand flats

A.1860 Cakile constricta Sparsely Vegetated Alliance


Gulf Sea-rocket Sparsely Vegetated Alliance

Alliance Concept

Summary: Annual-dominated sand flats on island end flats and upper ocean beaches, within the reach of storm tides and extreme lunar tides. This alliance has more perennial species than the related Cakile edentula Sparsely Vegetated Alliance (A.1861), since the Gulf Coast shoreline is a lower-energy system, and the alliance is less dynamic and less frequently disturbed. Other characteristic species include Iva imbricata, Ipomoea pes-caprae, and Ipomoea imperati.

Common Name:



Ecological System(s): Florida Panhandle Beach Vegetation (CES203.266)

Status: Standard Circumscription Confidence: 3 - Weak

Concept Author(s): A.S. Weakley

Element Concept

Global Summary: This type represents the eastern Gulf Coast upper ocean beach community. Other characteristic species include Iva imbricata, Atriplex cristata (= Atriplex pentandra), and Ipomoea imperati. This community occurs along driftlines formed by the highest spring tides and, on stable coasts, is annually destroyed and re-formed. On prograding beaches or beaches re-building after storm destruction of the foredune, this community may form the initial nucleus on which the foredune (dominated by Uniola paniculata) is re-built (A.F. Johnson pers. obs.).

Conservation Status Rank

Global Rank & Reasons: G2G3 (9-Jan-2000). Community is damaged by the practice of raking heavy driftline deposits off the beaches for aesthetic reasons at some resorts and beach parks. This association is naturally restricted to narrow bands along the eastern Gulf Coast from Mississippi to the panhandle of Florida. It is altered or destroyed in areas of development or heavy recreational use.
