CEGL008587 Quercus stellata - Pinus taeda Flatwoods Wet Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Post Oak - Loblolly Pine Flatwoods Wet Forest
Colloquial Name: West Gulf Coastal Plain Post Oak - Loblolly Pine Flatwoods
Hierarchy Level: Association
Type Concept: This association is found in the West and Upper West Gulf Coastal Plain ecoregions of eastern Texas and possibly adjacent areas of western Louisiana and Arkansas. Stands occur in slight topographic depressions or shallow ponds on Pleistocene high terraces. These forests are considered to be seasonally flooded since during average years they hold water for a portion of the growing season, albeit for very short duration. These areas may be best thought of as "flatwoods" as the source of the water in the depressions results from precipitation. These areas are dominated by Quercus stellata and Pinus taeda with average canopy cover of 80% or greater. No other tree species have been documented in the canopy of known examples. The understory is very open to sparse and contains Chasmanthium sessiliflorum and Chasmanthium laxum and relatively few additional species.

Floristics: Stands are dominated by closed to somewhat open forests in which the canopy and subcanopy cover is composed almost exclusively of Quercus stellata and Pinus taeda. The aspect of the pond is open under the canopy especially when compared to surrounding upland forests which may be densely shrubby. These ponds have a very sparse shrub and herbaceous layer which is not floristically rich. Shrubs include Ulmus alata, Ilex vomitoria, and Callicarpa americana. The sparse understory contains Chasmanthium sessiliflorum, Chasmanthium laxum, Carex glaucescens, and relatively few additional species (NatureServe Ecology unpubl. data).
Dynamics: No Data Available
Environmental Description: Stands of this association occur in slight topographic depressions or shallow ponds on Pleistocene high terraces. Soil moisture fluctuates widely throughout the growing season depending largely upon rain events which are well distributed throughout the year. Surface soils in these depressions appear to be finer textured than adjacent areas which may slow drainage of these areas. In addition, soils may have a hardpan which impedes the downward migration of water into the subsoil, causing a shallowly perched water table. The hardpan may also impede movement of water up to the dry surface soil from deeper, more moist soil in the summer and restrict the potential rooting depth of vegetation within these depressions. These depressions have been documented on soils mapped as Keithville-Sawtown on the Angelina and Sabine national forests (NatureServe Ecology unpubl. data).
Geographic Range: This forest is known from eastern Texas. It may also occur in western Louisiana and/or southern Arkansas.
