CEGL007955 Pinus taeda - (Quercus spp.) / Ostrya virginiana - Sabal minor Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Loblolly Pine - (Oak species) / Hophornbeam - Dwarf Palmetto Forest
Colloquial Name: West Gulf Coastal Plain Subcalcareous Loblolly Pine - Water Oak / Palmetto Riparian Forest
Hierarchy Level: Association
Type Concept: This Pinus taeda-dominated forest occurs in the southwestern extremity of the Upper West Gulf Coastal Plain of Texas and may occur elsewhere in the region. The most characteristic feature of this community is the strong dominance of Sabal minor. The overstory is dominated by Pinus taeda, followed closely by Quercus nigra, Ostrya virginiana, and Liquidambar styraciflua. Ostrya virginiana and Fraxinus americana are the most important midstory species. The understory is strongly dominated by Sabal minor with patches of sedges (Carex spp.) and other herbaceous species infrequently scattered throughout. Many of the plant species present are believed to indicate a rich nutrient and/or pH status in the region.

Classification Comments: This type may represent the western expression of ~Pinus taeda - Quercus alba - Carya tomentosa / Acer floridanum - (Acer leucoderme) Forest (CEGL007524)$$. The region of occurrence appears to represent a geographic area where range attenuations of important tree species takes place. For example, this area appears to be largely outside the range of Quercus alba and Acer leucoderme as well as Fagus grandifolia.

Floristics: The most characteristic feature of this community is the strong dominance of Sabal minor. The overstory is dominated by Pinus taeda. Portions of this community which receive temporary flooding from the stream may have some hardwoods in the overstory as well. Typical species are Quercus nigra, Ostrya virginiana, and Liquidambar styraciflua. The upland edges of this community, further away from the creek bank, may lack additional overstory trees. Additional overstory and subcanopy species include Quercus shumardii, Quercus texana (= Quercus nuttallii), Quercus similis, Ulmus alata, Ulmus americana, Morus rubra, Ilex opaca, Celtis laevigata, and Fraxinus americana. Ostrya virginiana and Fraxinus americana are the most important midstory species. The midstory and shrub layer may also include Forestiera ligustrina, Ilex decidua, Callicarpa americana, Crataegus spathulata, and Ulmus rubra. Parthenocissus quinquefolia is abundant in the understory, with the next most numerically important species being Carex albicans var. australis (= Carex physorhyncha), Carex cherokeensis, Carex abscondita, and Toxicodendron radicans. Patches of Thelypteris kunthii may be abundant at the base of the slope.

Environmental Description: This association has been documented from the Fleming Formation in eastern Texas on soils mapped as the Gowker series. Contrary to the hypothesis suggested by floristic indicator species, namely that the soils would be clayey and/or rich in nutrients and/or high in pH, soil samples revealed a pH of 5.6, with an upper surface texture dominated by sand, and relatively low levels of both calcium (99 ppm) and magnesium (22 ppm) (Turner et al. unpubl. data). This type is found at the base of a gradual sloping upland along lower slopes and flats near riparian areas. The lowermost portions of this community grade into small stream floodplains which could receive some temporary flooding (NatureServe Ecology unpubl. data). Small seepage areas are present along this ecotone.
Geographic Range: This type is known from eastern Texas and may be present in Arkansas and western Louisiana.
