CEGL008469 Quercus phellos - (Quercus lyrata) / Carex joorii - Saccharum baldwinii Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Willow Oak - (Overcup Oak) / Cypress Swamp Sedge - Narrow Plumegrass Floodplain Forest
Colloquial Name: Caddo Lake Bottomland Oak Flat
Hierarchy Level: Association
Type Concept: This association occurs on lower portions of islands and levees that gently slope downward into wetter swamps of Caddo Lake, Texas, and likely includes related vegetation of adjacent Louisiana and Arkansas. The description is based on the work of Van Kley and Hine (1998). These areas are seasonally flooded on poorly drained soils. Stands are typically dominated by Quercus phellos with lesser amounts of Quercus lyrata, Nyssa sylvatica, and Liriodendron tulipifera. Important shrubs include Crataegus opaca, Diospyros virginiana, Styrax americanus, Ilex decidua, and Forestiera acuminata. Diagnostic understory species are Carex joorii and Saccharum baldwinii. The understory vegetation may also include Hibiscus moscheutos, Brunnichia ovata, Boehmeria cylindrica, Acalypha virginica, Hypericum hypericoides, Berchemia scandens, Dichanthelium dichotomum, Trachelospermum difforme, and Toxicodendron radicans. Seedlings of Diospyros virginiana, Styrax americanus, Quercus lyrata, and Liquidambar styraciflua may be abundant.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Van Kley and Hine (1998) proposed three community subtypes: willow oak flat, dominated by willow oak and Carex joorii; willow oak mounds with dense Saccharum; and overcup oak flats (lower, wetter, than willow oak flat).
