CEGL004200 Carya illinoinensis - Ulmus crassifolia / Elymus virginicus Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pecan - Cedar Elm / Virginia Wildrye Floodplain Forest
Colloquial Name: Lampasas Cutplain Pecan - Cedar Elm Floodplain Forest
Hierarchy Level: Association
Type Concept: This forest is currently only known from moderately well-drained alluvial floodplains of the Leon River and Cowhouse Creek in the Lampasas Cutplain of central Texas. It may also extend into adjacent ecoregions. The vegetation is characterized by a closed-canopy forest dominated by Ulmus crassifolia and/or Carya illinoinensis. The canopy may also include Celtis laevigata var. laevigata, Celtis laevigata var. texana, Fraxinus pennsylvanica, Quercus macrocarpa, Juniperus virginiana, and Ulmus americana. In addition to canopy species, the midstory often includes Acer negundo, Maclura pomifera, Sideroxylon lanuginosum, and Sapindus saponaria. The understory is typically open with scattered shrubs, including canopy saplings and Forestiera pubescens, Callicarpa americana, Cornus drummondii, Frangula caroliniana, and Ilex decidua. Herbaceous ground cover is typically greater than 75% cover of a mixture of graminoids and forbs, including Elymus virginicus (which can have high cover), Carex bulbostylis, Geum canadense, Sanicula canadensis, Ruellia drummondiana, Chasmanthium latifolium, Verbesina virginica, Commelina erecta, Vernonia baldwinii, Symphyotrichum drummondii var. texanum, and Cocculus carolinus. Vines, including Toxicodendron radicans, Parthenocissus quinquefolia, Smilax rotundifolia, Smilax bona-nox, and Vitis cinerea, are a common component of this association and are typically present in all strata.

Dynamics: Deep alluvial soils and infrequent flooding are important environmental factors for this community.
Environmental Description: This forest is found on deep, moderately well-drained alluvial soils of the Leon River and Cowhouse Creek floodplains in the Lampasas Cutplain of central Texas.
Geographic Range: This forest is currently only known from the Lampasas Cutplain of central Texas. It may also occur in Oklahoma. Further investigation is needed to determine the full global range of this vegetation.
