CEGL008443 Quercus alba - Quercus stellata / Ostrya virginiana - Acer floridanum / Chasmanthium sessiliflorum Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: White Oak - Post Oak / Hophornbeam - Southern Sugar Maple / Longleaf Woodoats Forest

Colloquial Name: White Oak - Post Oak Subcalcareous Forest

Hierarchy Level:  Association

Type Concept: This dry oak-hickory forest occurs on subcalcareous substrates in northern Alabama, northwestern Georgia, and possibly adjacent states. It is dominated by Quercus alba and Quercus stellata, with other canopy components including Quercus shumardii, Quercus rubra, Carya glabra, Carya tomentosa, and Pinus echinata. The subcanopy is well-developed and consists of Ostrya virginiana, Acer floridanum, Nyssa sylvatica, Ulmus alata, and Juniperus virginiana var. virginiana. Shrubs and woody vines include Vaccinium stamineum, Crataegus sp., Toxicodendron radicans, and Smilax glauca. Herbs can include Chasmanthium sessiliflorum, Dichanthelium boscii, Dichanthelium spp., and Carex spp.

Classification Comments: This community needs additional rangewide assessment. It occurs in the same landscape as ~Quercus muehlenbergii - Quercus shumardii - Carya (carolinae-septentrionalis, ovata) Forest (CEGL007808)$$, ~Quercus alba - Quercus rubra - Quercus muehlenbergii / Cercis canadensis Forest (CEGL002070)$$, and ~Quercus shumardii - Quercus muehlenbergii - Acer (floridanum, saccharum) / Ostrya virginiana Forest (CEGL008442)$$. It is moister and less extremely calcareous than CEGL007808, somewhat drier and less calcareous than CEGL002070, and much drier and less calcareous than CEGL008442.

Floristics: This forest has a closed canopy dominated by Quercus alba and Quercus stellata, with other canopy components including Quercus shumardii, Quercus rubra, Carya glabra, Carya tomentosa (= Carya alba), and Pinus echinata (NatureServe Ecology unpubl. data). The subcanopy is well-developed and consists of Ostrya virginiana, Acer floridanum (= Acer barbatum), Nyssa sylvatica, Ulmus alata, and Juniperus virginiana var. virginiana. Shrubs and woody vines include Vaccinium stamineum, Crataegus sp., Toxicodendron radicans, and Smilax glauca. Herbs can include Chasmanthium sessiliflorum, Dichanthelium boscii, Dichanthelium spp., and Carex spp. A stand tentatively assigned here from the Talladega National Forest contains Carya tomentosa, Acer leucoderme, and some other taxa which were not part of the original description, but the plot is generally compatible with this type.

Dynamics:  This community is presumably quite stable. Low-intensity surface fires probably naturally burned into stands of this community from more xeric upslope communities.

Environmental Description:  This association occurs on dry (upper slope, south-facing) sites over mixtures of calcareous and non-calcareous rocks, or over subcalcareous rocks. A stand from the "Red Knobs" landform in a small portion of the Ridge and Valley (221Jb) which is part of the Cherokee National Forest has been attributed to this type.

Geographic Range: This community is known from calcareous and subcalcareous areas of the southern Cumberlands and Southern Ridge and Valley provinces of Alabama, southern Tennessee, and probably northwestern Georgia.
