CEGL004196 Quercus macrocarpa - Carya illinoinensis / Cornus drummondii - Frangula caroliniana Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bur Oak - Pecan / Roughleaf Dogwood - Carolina Buckthorn Floodplain Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest is found on well-developed alluvial floodplains and terraces along major streams and rivers in the Lampasas Cutplain in central Texas. Soils are deep, variable in texture and poorly drained to well-drained. Typically, Quercus macrocarpa and Carya illinoinensis codominate the canopy of this forest. Other characteristic canopy trees may include a variable mixture of Ulmus crassifolia, Ulmus americana, Celtis laevigata var. laevigata, Celtis laevigata var. texana, Juniperus virginiana, Morus rubra, and Juglans nigra. The midstory includes many canopy species and some small trees, including Cornus drummondii, Frangula caroliniana, Ilex decidua, and Sideroxylon lanuginosum. The understory, which can be dense in patches, may include many of the above plus Forestiera pubescens, Viburnum rufidulum, and Ptelea trifoliata. Components of the sparse to patchy ground cover include Geum canadense, Sanicula canadensis, Ruellia drummondiana, Ruellia humilis, Chasmanthium latifolium, Galium circaezans, Desmodium tweedyi, Verbesina virginica, Vernonia baldwinii, Desmodium paniculatum, 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.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is classed in a pecan-dominated alliance (~Fraxinus pennsylvanica - Carya illinoinensis - Quercus macrocarpa Great Plains Floodplain Forest Alliance (A3680)$$) because of the strong component of Carya illinoinensis and because it often grades into vegetation dominated by Carya illinoinensis but missing Quercus macrocarpa. More investigation is needed to understand the relationship of this vegetation to ~Quercus macrocarpa - Quercus shumardii - Carya cordiformis / Chasmanthium latifolium Floodplain Forest (CEGL004544)$$ in ~Liquidambar styraciflua - Fraxinus pennsylvanica - Acer rubrum Flooded & Swamp Forest Alliance (A3625)$$.
