In 1918, W. L. McAtee described the “magnolia bogs” as a distinctive habitat present in a few dozen places on the innermost Coastal Plain (near the Fall Line) in the Washington, D.C., area. Occurring where cool water seeps from hillside gravel deposits, these specialized wetlands are characterized by the presence of the native sweetbay magnolia (Magnolia virginiana) as well as other distinctive plants, such as peat moss (Sphagnum) and poison sumac (Toxicodendron vernix). While many of McAtee’s localities have been destroyed or badly degraded by development over the past decades, a few good examples remain. This natural community of VA is now Critically Impaired globally and statewide, G1/S1.
