CEGL007951 Ulmus alata - Liquidambar styraciflua / Celtis laevigata / Trepocarpus aethusae Calcareous Floodplain Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Winged Elm - Sweetgum / Sugarberry / White-nymph Calcareous Floodplain Forest

Colloquial Name: Southern Loam Hills Calcareous Floodplain Forest (Disturbed Type)

Hierarchy Level:  Association

Type Concept: This calcareous floodplain forest occurs along the southwestern periphery of the Upper West Gulf Coastal Plain ecoregion of eastern Texas. Presumably this type has been degraded by past land uses, probably including "high-grading" (selective removal of commercially valuable oaks). In addition to Ulmus alata and Liquidambar styraciflua, Quercus nigra also reaches the overstory. Sabal minor may be abundant in the understory along with scattered Crataegus spathulata, Forestiera ligustrina, Ulmus crassifolia, Symphoricarpos orbiculatus, Arundinaria gigantea, Parthenocissus quinquefolia, and Celtis laevigata. Geum canadense, Ruellia caroliniensis, Arisaema dracontium, Carex blanda, Carex albolutescens, Carex cherokeensis, Carex amphibola, Carex abscondita may also be common.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This type represents variation in existing vegetation finer than what is currently considered necessary at the association level. Therefore it is designated provisional. Type was originally defined by Turner et al. (unpubl. data) from the Sam Houston National Forest. The absence of other typical hardwood bottomland species may be due, in part, to artificial disturbance or "high-grading."
