CEGL005024 Populus deltoides / Pascopyrum smithii - Panicum virgatum Floodplain Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Eastern Cottonwood / Western Wheatgrass - Switchgrass Floodplain Woodland
Colloquial Name: Cottonwood / Western Wheatgrass - Switchgrass Floodplain Woodland
Hierarchy Level: Association
Type Concept: This association has been identified in the panhandle of northern Texas. The woodland occurs on mesic sites near rivers and large streams. Soils are sandy and formed from alluvium. The canopy is moderate and formed almost exclusively of Populus deltoides. Shrub cover is sparse. Perennial grasses dominate the understory forming a moderate to dense herbaceous stratum. Pascopyrum smithii and Panicum virgatum are the dominants, usually with lesser amounts of Elymus canadensis.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The global information was derived from data from northern Texas but is very similar to an association proposed from Colorado data (Populus deltoides / Pascopyrum smithii - Panicum obtusum Woodland). The relationship of these two associations and the possibility of combining them need to be further investigated.

Physiognomy and Structure: No Data Available
Floristics: This community is an open woodland with tree canopy cover averaging 25-35%. Populus deltoides is the major tree species. Few shrubs are present in general, but scattered Rhus trilobata, Baccharis salicina, Amorpha fruticosa, Prunus gracilis, and shrubby Celtis laevigata occur. Shrub cover is usually less than 10%. The understory vegetation is mainly perennial grasses with cool-season grasses dominating. The major species of grass is Pascopyrum smithii. Lesser amounts of Elymus canadensis also occurs. The predominant warm-season grass is Panicum virgatum. This understory is often shaded most of the day. Grasses make up the majority of the understory with forbs usually being 10 to 15%. Most frequently found forb species include Ambrosia psilostachya, Gaura suffulta, Gaura coccinea, Heterotheca subaxillaris (= Heterotheca latifolia), Symphyotrichum ericoides (= Aster ericoides), and Glycyrrhiza lepidota.
