Proceedings of the Back Bay Ecological Symposium
Back Bay Ecological Symposium
(First Paragraph) Past authors who documented the distributions of eastern North American amphibians and reptiles illustrated the southeastern corner of Virginia as the northern limit of distribution for many species (Conant 1958, 1975; Martof et al. 1980). These maps were not sufficiently detailed to allow resolution of specific areas; the entire region was completely shaded.
