CEGL007112 Quercus phellos - Quercus similis Pond Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Willow Oak - Bottomland Post Oak Pond Forest
Colloquial Name: Southern Interior Highlands Oak Flatwoods
Hierarchy Level: Association
Type Concept: This willow oak - bottomland post oak flatwoods is found in the Interior Highlands in Arkansas (and perhaps Oklahoma and Missouri). These flatwoods are characterized by a strongly fluctuating seasonal moisture regime (xerohydric). Stands of this community are codominated by Quercus phellos, which may be the sole dominant, along with Quercus similis. It occurs on poorly drained flats which usually have a fragipan. Additional characteristic overstory and midstory species include Quercus pagoda and Carya ovata. The flats are often mounded and may have substantial depressions that pond water (and if extensive enough, these may be classified as ~Quercus phellos Ozark Pond Forest (CEGL007402)$$ or ~Quercus lyrata Pond Forest (CEGL004642)$$). These geomorphic features allow hydrophytic species such as Quercus lyrata or mesophytic species such as Quercus alba, Quercus nigra, and Carya tomentosa to codominate, and even allow some xerophytic species such as Quercus stellata and Carya texana to occur, thereby allowing for high species diversity in stands of this type.

Floristics: Stands are codominated by Quercus phellos, which may be the sole dominant, and Quercus similis. Additional characteristic overstory and midstory species include Quercus pagoda and Carya ovata. Geomorphic variation allows hydrophytic species such as Quercus lyrata or mesophytic species such as Quercus alba, Quercus nigra, and Carya tomentosa (= Carya alba) to codominate, and even allow some xerophytic species such as Quercus stellata and Carya texana to occur, thereby allowing high species diversity.
Dynamics: Because of the summer-fall dry conditions, fire is frequent in the community, enhanced by the landscape within which the community exists - upland hardwood or upland pine hardwood forests or woodlands, dry to dry-mesic, that burn frequently. Windthrow is common because of shallow rooting depth, and ice damage occurs.
Environmental Description: Soils are slowly to very slowly permeable due to high clay content or the presence of a fragipan. This results in a shallow, perched water table during the rainy season (winter and spring) and limited available moisture during the summer and fall (xerohydric moisture regime), thereby restricting rooting depth and excluding mesophytic species. However, sites are often mounded and have depressions, allowing both mesophytic and hydrophytic species to become important. Because of the summer-fall dry conditions, fire is frequent in the community, enhanced by the landscape within which the community exists - upland hardwood or upland pine-hardwood forests or woodlands, dry to dry-mesic, that burn frequently.
Geographic Range: This association is found in the Interior Highlands of Arkansas, as well as possibly adjacent Missouri and Oklahoma.
