Abstract:

Concern about declining amphibians is increasing worldwide. Recent reports indicate that the range of Blanchard's cricket frog (Acris crepitans blanchardi) is decreasing from north to south. This study surveys both historic and new possible sites for Blanchard's cricket frogs in southwestern Minnesota.

Three visits were made to each of ten locations in the southwestern Minnesota counties of Pipestone, Rock, and Nobles. These sites included five historical locations and five new locations. At least one diurnal visit was made to each site to evaluate the habitat.

There were no extant populations of Acris crepitans blanchardi found in southwestern Minnesota. The habitat appears to be suitable for cricket frogs, despite modifications to the original habitat. Future work needs to be done to determine the cause of the apparent decline in range of the cricket frog.
