Reptiles and amphibians, or herpetofauna, have the highest extinction rates of any vertebrate group. We established a herpetofauna monitoring research project at Michigan State University’s Corey Marsh Ecological Research Center (CMERC) to better understand the diversity and abundance of local herpetofauna populations. The two focal survey methods were passive acoustic recording of frogs and capture-mark-recapture of turtles using aquatic traps. Additionally, we implemented salamander false cover surveys in partnership with the Salamander Population Adaptation Research Collaborative Network (SPARCnet). We identified eight species of frogs and three species of turtles in total between 2022 - 2024. Frog species at CMERC included spring peepers (Pseudacris crucifer), western chorus frogs (Pseudacris triseriata), eastern gray treefrogs (Hyla versicolor), green frogs (Lithobates clamitans), wood frogs (Lithobates sylvaticus), northern leopard frogs (Lithobates pipiens), bullfrogs (Lithobates catesbeianus), and American toads (Anaxyrus americanus). Turtle species at CMERC included painted turtles (Chrysemys picta), common snapping turtles (Chelydra serpentina), and Blanding’s turtles (Emydoidea blandingii). Salamander species at CMERC solely included the blue-spotted salamander (Ambystoma laterale). We also assessed frog reproductive phenology (timing of calling) for P. crucifer, P. triseriata, H. versicolor, and L. clamitans. We found that calling frequency is related to the time of year for all four species, but most strongly with early spring breeders such as P. crucifer and P. triseriata. Similarly, P. crucifer calling frequency has a low negative correlation with temperature, suggesting that P. crucifer is especially reliant on low early spring temperatures and may be more sensitive to the effects of climate change. Our results provide important baseline herpetofauna data for CMERC and will help guide future habitat restoration, wildlife conservation, and monitoring efforts on the site. Finally, the project has collectively engaged ~500 students, postdocs, faculty, and community partners, providing both research professional development and networking opportunities.
