CEGL004068 Quercus alba - Quercus falcata - Quercus velutina / Ostrya virginiana Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: White Oak - Southern Red Oak - Black Oak / Hophornbeam Forest

Colloquial Name: Southern Crowley''s Ridge Dry-Mesic Oak Forest

Hierarchy Level:  Association

Type Concept: This dry-mesic oak forest occurs on rich, loessal soils of the southern portion of Crowley''s Ridge, Arkansas, on middle and upper slopes and undulating narrow finger ridges. Examples are dominated by Quercus alba and Quercus falcata, with a significant component of Quercus velutina. The subcanopy includes the overstory species as well as Ostrya virginiana, Cornus florida, Carya tomentosa, Liriodendron tulipifera, and Magnolia acuminata. A number of species may be present in the herbaceous layer.

Floristics: This forest has a closed canopy dominated by Quercus alba. Quercus falcata is locally diagnostic of this type and suggestive of the intermediate moisture status (it tends to be absent from more mesic stands, while drier stands support Quercus stellata). Cornus florida appears to also indicate this moisture status. Quercus velutina may be common in the overstory of these stands but is also common in more mesic stands on Crowley''s Ridge (NatureServe Ecology unpubl. data). Other woody species may include Ostrya virginiana, Cornus florida, Carya tomentosa (= Carya alba), Carya pallida, Diospyros virginiana, Ulmus alata, Liriodendron tulipifera, and Magnolia acuminata (NatureServe Ecology unpubl. data). A number of species may be present in the herbaceous layer, including Maianthemum racemosum, Sanicula canadensis, Toxicodendron radicans, Campsis radicans, Smilax bona-nox, Chasmanthium sessiliflorum, Dichanthelium boscii, Polystichum acrostichoides, Carex spp., and others.

Dynamics:  The landscape in which this community occurs is highly dissected and surrounded by ravines and bottomlands. These factors suggest that naturally occurring fire events would have been rare. However, it is not clear how stable this oak-dominated forest would be given continued invasion of more mesic species from the surrounding areas. Some form of fire management may be necessary to maintain oak dominance and regeneration.

Environmental Description:  This association has been documented from southern Crowley''s Ridge, Arkansas, on upper to middle slopes. This landscape is highly dissected, and dry uplands are quite uncommon and restricted in size. This forest occurs downslope of the driest forests known in the area. The loessal soils on which this type is found appear to be rich and productive, facilitating the development of closed-canopy forests.

Geographic Range: As currently understood and documented, this community is restricted to loess soils of Crowley''s Ridge, Arkansas. It is unclear if this type occurs in related areas of Missouri.
