Native to streambanks, floodplains, and other moist areas of the eastern United States, the River Birch is notable for its distinctive exfoliating bark and ability to withstand higher temperatures, unlike other native birch species. Betula nigra was included in both Bartram’s Catalogue of American Trees, Shrubs, and Herbacious Plants (1783) and as a native tree “useful for fabrication” in Jefferson’s Notes on the State of Virginia (1780s). The hard, strong, close-grained wood was once used for furniture-making and wooden objects such as ox yokes and hoops for rice casks.
