Type Concept: This dense, broad-leaved, winter-deciduous riparian copse is dominated by Cephalanthus occidentalis, usually as tall shrubs (6-9 m [20-30 feet]) but in some areas reaching to 18 m (60 feet). It prefers quiet waters like sloughs and oxbow lakes, but is restricted to intermittently flooded, seasonally saturated floodplains. It requires poorly aerated, fine-textured soils with seasonal flooding and a high water table. Cephalanthus occidentalis is the sole or dominant shrub in the canopy. Other species that may be present include Cornus sericea, Salix lucida ssp. lasiandra and Salix exigua. Shrubs typically are less than 10 m in height; the canopy is continuous, intermittent or open. The herbaceous layer can be sparse or grassy.
