Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Live Oak - Pecan Woodland
Colloquial Name: Texas Upper Coastal Prairie Live Oak - Pecan Woodland
Hierarchy Level: Association
Type Concept: This woodland of the Upper Coastal Prairie region of Texas occurs within a matrix of coastal grassland. It is characterized by an open, patchy canopy with grass-dominated openings. The overstory is dominated by Quercus virginiana and Carya illinoinensis with lesser amounts of Celtis laevigata var. laevigata, Quercus stellata, and Ulmus alata. The understory typically includes Ilex vomitoria, Crataegus spp., Diospyros virginiana, and Sideroxylon sp. Common herbaceous species include Paspalum plicatulum, Axonopus spp., and Schizachyrium scoparium. This community occurs over heavy-textured, neutral or basic soils on elevated areas within the coastal prairie. It is found in floodplains, but is rarely flooded.

Floristics: This mainly deciduous woodland is characterized by an open, patchy canopy with grass-dominated openings. The overstory is dominated by Quercus virginiana and Carya illinoinensis with lesser amounts of Celtis laevigata var. laevigata, Quercus stellata, and Ulmus alata. The understory typically includes Ilex vomitoria, Crataegus spp., Diospyros virginiana, and Sideroxylon sp. Common herbaceous species include Paspalum plicatulum, Axonopus spp., and Schizachyrium scoparium.
Dynamics: Fire and edaphic characteristics are thought to have played a role in the maintenance of this community in a woodland state. In the absence of fire, the canopy may approach forest stature.
Environmental Description: This woodland occurs within a matrix of coastal grassland, over heavy-textured, neutral or basic soils on elevated areas within the of the Upper Coastal Prairie region of Texas. It is found in floodplains, but is rarely flooded.
Geographic Range: This community occurs only within a small area on the Gulf Coast of Texas (Upper Coastal Prairie), on uplands between the Colorado, San Bernard, and Brazos rivers.
