Name: Betula nigra - Quercus laurifolia - Taxodium (distichum, ascendens) / Crataegus aestivalis Forest Reference: NatureServeExplorer 9/14/2010 Description: This association occurs on relatively young deposits of sand along blackwater rivers, generally on point bars, but sometimes as a poorly developed natural levee along other portions of the river. These substrates are older and more stable than those of the open sand bar communities but younger than those of other floodplain communities. Vegetation is of varying structure, ranging from forest to woodland, often with leaning trees and no clearly defined strata. The canopy is generally dominated by Betula nigra, Taxodium sp., and various bottomland oaks. Crataegus aestivalis, Fraxinus caroliniana, and in more southerly areas, Planera aquatica are often present. Shrubs are generally sparse, but patches of Cyrilla racemiflora, Alnus serrulata, Vaccinium elliottii, or other species of riverbanks or bottomland hardwoods may be present. Herbs are generally sparse. They most typically include species of open bars, such as Panicum rigidulum, and may also include species of swamps, such as Polygonum spp. (= Persicaria spp.) and Hymenocallis spp.  Accession Code: urn:lsid:cvs.bio.unc.edu:commConcept:28542-{A7426034-CACF-4353-914B-5D877A612D04} Plot-observations of this Community Concept: 1
