Blanchard's Cricket Frogs, Acris crepitans blanchardi, historically occurred in Clay, Mason, Putnam, and Wayne counties of West Virginia. It has been since 1948 that a specimen was collected from these counties or any other in this state. The first objective of this study was to gather natural history information on A. c. blanchardi based on a population in Lawrence County, Ohio. The second objective of this study was to determine if A. c. blanchardi has been extirpated from West Virginia. The third objective was to determine differences between historical, potential, and current population sites based on vegetation sampling, predators, water chemistry, and environmental parameters including ultraviolet light penetration, relative humidity and air, soil, and water temperatures.
