CEGL002091 Ulmus (americana, rubra) - Quercus muehlenbergii Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (American Elm, Slippery Elm) - Chinquapin Oak Floodplain Forest
Colloquial Name: Southern Elm - Chinquapin Oak Mesic Floodplain Forest
Hierarchy Level: Association
Type Concept: This forest is known from floodplains in the Crosstimbers Region of Oklahoma and Texas. The canopy of this forest is characteristically dominated by some combination of Ulmus americana, Ulmus rubra, and Quercus muehlenbergii. Other characteristic species include Aesculus glabra, Celtis laevigata, Quercus macrocarpa, Quercus rubra, and Frangula caroliniana, the latter as a shrub.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The discussion of the proper placement of this association has been a subject of contention since 2001. At that time, it was proposed that it be moved to a non-wetland part of the hierarchy. Information on it is incomplete. In the revised hierarchy, the best placement is in a floodplain macrogroup and group, with CEGL002090, even though it is less wet and more "mesic" than CEGL002090. Hoagland (2000) places this in an Ulmus (americana/rubra) Forest Alliance, and states that the habitat of that alliance is "wet to mesic soil in riparian corridors" which implies that the global placement in ~Fraxinus pennsylvanica - Carya illinoinensis - Quercus macrocarpa Great Plains Floodplain Forest Alliance (A3680)$$ is plausible. More information is needed.

Environmental Description: Hoagland (2000) places this in his Ulmus (americana/rubra) Forest Alliance, and states that the habitat of that alliance is "wet to mesic soil in riparian corridors." There is a contrast with the wetter ~Ulmus americana - Celtis (laevigata, occidentalis) - Fraxinus pennsylvanica Floodplain Forest (CEGL002090$$. Both associations may be in floodplains, with this association (CEGL002091) going up onto mesic slopes. More information is needed.
Geographic Range: This forest is known from the Crosstimbers Region of Oklahoma and Texas. Hoagland (2001) states that it is distributed in "eastern Oklahoma with localized occurrences in the west."
