CEGL008468 Ulmus crassifolia - Celtis laevigata / Ilex decidua / Elymus virginicus Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Cedar Elm - Sugarberry / Possum-haw / Virginia Wildrye Floodplain Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs on alluvial terraces and floodplains along rivers and streams in central and southern Texas. Composition is quite variable, but the overstory is typically dominated by Ulmus crassifolia and Celtis laevigata. Other characteristic overstory species may include Ulmus americana, Fraxinus pennsylvanica, Tilia americana var. caroliniana, and Carya illinoinensis. Midstory trees that may reach into the overstory include Acer negundo, Juglans major, Juglans microcarpa, Sapindus saponaria var. drummondii, Sideroxylon lanuginosum, and Styphnolobium affine. Typical components of the generally open understory include Ilex decidua, Forestiera pubescens, Cornus drummondii, Symphoricarpos orbiculatus, and occasionally Lindera benzoin and Juniperus ashei. The herbaceous layer is dense in patches and may include Elymus virginicus, Chasmanthium latifolium, Setaria scheelei, Carex amphibola, and Verbesina virginica.

Floristics: Composition is quite variable, but the overstory is typically dominated by Ulmus crassifolia and Celtis laevigata. Other characteristic overstory species may include Ulmus americana, Fraxinus pennsylvanica, Tilia americana var. caroliniana (= Tilia caroliniana), and Carya illinoinensis. Other trees that form a midstory, sometimes reaching into the overstory, may include Acer negundo, Juglans major, Juglans microcarpa, Sapindus saponaria, Sideroxylon lanuginosum, and Styphnolobium affine (= Sophora affinis). Typical components of the generally open understory include Ilex decidua, Forestiera pubescens, Cornus drummondii, Symphoricarpos orbiculatus, and occasionally Lindera benzoin and Juniperus ashei. The herbaceous layer is dense in patches and may include Elymus virginicus, Chasmanthium latifolium, Setaria scheelei, and Verbesina virginica.
Dynamics: Though this association is found within floodplains, flooding is usually infrequent and of short duration.
Environmental Description: This association occurs on alluvial terraces and floodplains along rivers and streams in central and southern Texas. Soils are typically calcareous and loamy.
Geographic Range: This association is found in eastern and southern Edwards Plateau, northern Tamaulipan Thorn Scrub and possibly southeastern Chihuahuan Desert ecoregions.
