CEGL002107 Quercus virginiana - Quercus nigra / Chasmanthium latifolium Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Live Oak - Water Oak / Indian Woodoats Forest
Colloquial Name: Live Oak - Water Oak Forest
Hierarchy Level: Association
Type Concept: This bottomland hardwood forest occurs along small rivers and streams within the historic coastal prairie matrix, now mostly in agriculture or pasture, that once covered the large parts of the Pleistocene terraces of the Beaumont, Lissie and possibly Willis formations of the upper Texas coast. It also occurs within the large bottomland hardwood system that spans the lower reaches of the Colorado, San Bernard and Brazos rivers (Columbia Bottomlands), where they traverse this historic coastal prairie matrix. The canopy may be codominated by Quercus virginiana and Quercus nigra or dominated solely by Quercus nigra. Other trees that may be present include Carya illinoinensis, Ulmus americana, Ulmus crassifolia, Celtis laevigata, and Platanus occidentalis within its range. Understory components include Ilex vomitoria, Crataegus spp., and Ilex decidua. The patchy herbaceous layer may include Calyptocarpus vialis, Chasmanthium latifolium, Elephantopus carolinianus, Elymus virginicus, Phanopyrum gymnocarpon, Paspalum langei and Geum canadense. Characteristic woody lianas include Nekemias arborea, Campsis radicans, Cocculus carolinus, Smilax bona-nox, Toxicodendron radicans, and Vitis mustangensis. The exotics Poncirus trifoliata, Solanum pseudocapsicum and Triadica sebifera are also present in some examples.

Floristics: The canopy may be codominated by Quercus virginiana and Quercus nigra or dominated solely by Quercus nigra. Other trees that may be present include Carya illinoinensis, Ulmus americana, Ulmus crassifolia, Celtis laevigata, and Platanus occidentalis within its range. Understory components include Ilex vomitoria, Crataegus spp., and Ilex decidua. The patchy herbaceous layer may include Calyptocarpus vialis, Chasmanthium latifolium, Elephantopus carolinianus, Elymus virginicus, Phanopyrum gymnocarpon (= Panicum gymnocarpon), Paspalum langei and Geum canadense. Characteristic woody lianas include Nekemias arborea (= Ampelopsis arborea), Campsis radicans, Cocculus carolinus, Smilax bona-nox, Toxicodendron radicans, and Vitis mustangensis. The exotics Poncirus trifoliata, Solanum pseudocapsicum (= Solanum capsicastrum), and Triadica sebifera (= Sapium sebiferum) are also present in some examples.
Dynamics: No Data Available
Environmental Description: Some occurrences of this association are found on sandy river terraces and natural levee ridges that receive overbank flooding. Other occurrences are located within historic floodplains that no longer receive regular overbank flooding but are saturated to the surface for periods of time during the growing season. The hydrology of the lower, flatter, poorly drained portions of these forests appears saturated, while the higher, better drained portions appear temporarily flooded.
Geographic Range: As currently described, this association is limited to the historic and current floodplains of the Brazos, San Bernard and Colorado rivers and their tributaries in the Gulf Coast Prairies and Marshes of Texas (Ecoregion 31).
