CEGL007992 Taxodium distichum - (Nyssa aquatica) - Carya aquatica / Planera aquatica Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bald-cypress - (Water Tupelo) - Water Hickory / Planertree Floodplain Forest
Colloquial Name: Upper West Gulf Coastal Plain Saturated River Channel
Hierarchy Level: Association
Type Concept: This hydric, permanently flooded forest community occurs in the channels and on the low banks of small to medium-sized rivers with swift currents (not a swamp) on the Upper West Gulf Coastal Plain of southern Arkansas. The low banks flood frequently, deeply (2.4+ m [8+ feet]), and remain inundated with swift flows for long periods. The soils are unknown. The canopy is open to partially closed with tall (37+ m [120+ feet]), buttressed, emergent Taxodium distichum and a midstory of Nyssa aquatica (where extant). The channels are dominated by Taxodium distichum frequently with Nyssa aquatica. The low bank is also dominated by Taxodium distichum with Carya aquatica and Planera aquatica. The same species sometimes form a shrub layer especially when beaver are present. No shrubs, woody vines, or herbaceous layer is extant. No litter or duff layer is extant, but large woody debris is common. This community abuts ~Betula nigra - Platanus occidentalis / Berchemia scandens / (Arundinaria gigantea) - Boehmeria cylindrica Floodplain Forest (CEGL007983)$$ and other riverfront forest communities. High-quality examples are known from Big Cypress Unique Area and Moro Bottoms Natural Area (without Nyssa aquatica). The type location is in Dallas County, Arkansas. This community is also known from Cleveland County and is likely extant throughout the Ouachita River Basin.
