Humbug Marsh Reptiles & Amphibians

Amphibians and reptiles are an important component of the Humbug Marsh ecosystem and are recognized as key biological indicators of environmental quality. Seven species of amphibian and reptile were observed during a 2005 survey. Of particular importance was the observation of a juvenile Elaphe vulpine gloydi (eastern fox snake), a species protected throughout its range and listed as Threatened in Michigan. This coastal marsh-dependant species is an important member of these ecosystems and is currently a candidate species being considered for Federal protection. Several areas in Humbug Marsh provide valuable hibernacula habitat for this snake. Mifsud (2005) estimates that at least nineteen additional species of herpetofauna may occur within the complex. Historically, Humbug Marsh provided habitat for Acris crepitans (Blanchard's cricket frog), now extirpated from the Detroit River corridor. Potential exists for the return of this species, provided wetland restoration is emphasized throughout the region. Future surveys are needed, but data has shown that the type of habitat found within Humbug Marsh has the potential to support several species listed as Special Concern in Michigan as well as a number of "Species of Greatest Conservation Need" identified by the Michigan Department of Natural Resources Wildlife Action Plan.
