Fraxinus americana - Carya glabra / Symphoricarpos orbiculatus - Rhus aromatica / Piptochaetium avenaceum Woodland
Translated Name: White Ash - Pignut Hickory / Coralberry - Fragrant Sumac / Blackseed Speargrass Woodland
Common Name: Piedmont Granitic Dome Woodland (Basic Type)
Unique Identifier: CEGL003684
Classification Approach: International Vegetation Classification (IVC)
Summary: Woodlands dominated by Fraxinus americana and Carya glabra, occurring in nutrient-rich soils apparently derived from plagioclase-rich granitic rocks in the Piedmont of North Carolina and Georgia. Other canopy species include Quercus prinus, Juniperus virginiana var. virginiana, Ulmus alata, Carya pallida, and Pinus virginiana. Shrub species include Symphoricarpos orbiculatus, Rhus aromatica var. aromatica, Ptelea trifoliata, Spiraea betulifolia var. corymbosa, Vaccinium stamineum, Vaccinium arboreum, Viburnum rufidulum, Juniperus virginiana var. virginiana, and Chionanthus virginicus. Typical herb species include Piptochaetium avenaceum, Arabis laevigata, Arabis canadensis, Arabis hirsuta var. pycnocarpa (= Arabis hirsuta var. adpressipilis), Anemone virginiana, Anemone berlandieri, Asplenium platyneuron, Melica mutica, Tradescantia ohiensis, Packera obovata (= Senecio obovatus), Allium cuthbertii, Phlox nivalis ssp. hentzii, Aquilegia canadensis, Cunila origanoides, Verbesina occidentalis, Woodsia obtusa, and Carex pensylvanica.



Classification

Classification Confidence: Low
Classification Comments: Possibly needs to be broadened in concept to include other circumneutral woodlands with more or less this canopy, but possibly other shrub components, such as Philadelphus inodorus and Philadelphus hirsutus. This association was originally defined for woodlands developed on nutrient-rich granitic domes in the far western Piedmont of North Carolina; very similar communities occur on Stone Mountain, Georgia, with various plants rare in Georgia, including Ribes curvatum (G4) and Viburnum rafinesquianum (= var. rafinesquianum). More information is needed to determine the status of this type on the Oconee National Forest and nearby Piedmont National Wildlife Refuge (Georgia).

Ecological System Unique ID Ecological System Name
CES202.328 Southern Piedmont Glade and Barrens


NatureServe Conservation Status
Global Status: G2 (11Dec1998)
Rounded Global Status: G2 - Imperiled
Reasons: This community is known from only 5-10 sites, where it occurs in areas of 10 to about 250 acres. All known sites are on Piedmont granite domes with apparently nutrient-rich seepage, perhaps related to plagioclase veins. Known locations are in the Brushy Mountains of North Carolina (Alexander and Wilkes counties, North Carolina, such as Joe Mountain, Little Joe Mountain, Sugarloaf Mountain, Pores Knob, and Little Mountain), and on Stone Mountain, Georgia. Some sites have been degraded by logging or pasturing. Joe and Little Joe Mountain is a Nature Conservancy preserve, and Stone Mountain is a state park (though with heavy recreational use).

Environmental Setting

Wetland Indicator: N
Environmental Summary: These woodlands occur in nutrient-rich soils apparently derived from plagioclase-rich granitic rocks in the Piedmont of North Carolina and Georgia. The known sites are on granite domes with apparently nutrient-rich seepage, perhaps related to plagioclase veins. The placement in a "glade"-related Ecological System is due to its association with granitic domes.
