CEGL007549 Quercus lyrata - Quercus phellos - Ulmus americana / Rhynchospora spp. Wet Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Overcup Oak - Willow Oak - American Elm / Beaksedge species Wet Forest
Colloquial Name: Red River Pimplemound Terrace Depression Oak Forest
Hierarchy Level: Association
Type Concept: This community occurs in seasonally flooded depressions in old meander scars on second terraces of ancient Red River alluvial valleys in Louisiana and possibly Arkansas and Texas. Microtopographic highs and lows (pimple mounds) are sometimes present. In these situations, this association occurs in the low areas between the mounds. It is not subject to riverine flooding. Characteristic canopy species include Quercus lyrata, Quercus phellos, Ulmus americana, Liquidambar styraciflua, Quercus nigra, Diospyros virginiana, Quercus stellata, Ulmus alata, Fraxinus caroliniana, and, less frequently, Salix nigra and Gleditsia aquatica. Herbaceous species are Polygonum hydropiperoides, Cardamine bulbosa, Amsonia tabernaemontana, Physostegia intermedia, Carex spp., Rhynchospora spp., Hibiscus lasiocarpos, Chasmanthium laxum, Pluchea sp., Bidens aristosa, Juncus sp., Panicum spp., Lycopus virginicus, and Hypericum hypericoides.
Diagnostic Characteristics: No Data Available
