A survey of vernal, pool-breeding Ambystoma was conducted during the springs of 1984-1986 in Hardin County, Ohio. Four species (A. jeffersonianum, A. maculatum, A. texanum and A. t. tigrinum) and several Ambystoma hybrids were collected. Only A. texanum had previously been reported from Hardin County. Ambystoma texanum dominated collections from the Blanchard River and Hog Creek drainages; A. maculatum and A. t. tigrinum were more common in the Scioto River drainage. These differences in distribution are probably due to variations in topography and vernal pool depth.
