Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: River Birch / Black Willow / Shrubby St. John''s-wort - Peppervine Floodplain Forest
Colloquial Name: East Gulf Coastal Plain Riverfront Forest
Hierarchy Level: Association
Type Concept: This temporarily flooded riverfront association is found along temporarily flooded natural levees and floodplains of brownwater rivers in the East Gulf Coastal Plain, where Betula nigra-dominated vegetation occurs south of the range of Platanus occidentalis. The canopy is dominated by Betula nigra, with Liquidambar styraciflua and an occasional Pinus taeda. Quercus laurifolia may also occur in some examples. The subcanopy may contain Salix nigra, Salix caroliniana, Acer rubrum, Carpinus caroliniana, Planera aquatica, and Cornus foemina. Hypericum prolificum is a prominent shrub in some examples. Vines, such as Smilax bona-nox, Campsis radicans and Nekemias arborea, are common. Herbs (Alabama) include Penthorum sedoides, Sagittaria sp., Polygonum sp., Mimulus sp., Leersia hexandra?, and Boehmeria cylindrica. Other herbs (Florida) include Panicum rigidulum, Solidago leavenworthii, Symphyotrichum sp., Dichanthelium commutatum, Saccharum baldwinii, Paspalum laeve, Amsonia rigida, Carex sp., and Justicia ovata.
