2025 Bioblitz at Eagle Marsh

A Bioblitz is a 24-hour survey of all living organisms in a specific area, bringing together professionals and enthusiasts who specialize in different taxa to document biodiversity. On Saturday, May 31st, the Indiana Academy of Science hosted its annual Bioblitz at Eagle Marsh and Little River Wetlands in Fort Wayne—an 800+ acre area of restored wetlands and former farmland.

The Hoosier Herpetological Society was well represented, with members Ethan Estabrook, Brenten Ruest, Yusnaviel Garcia, and Jim Horton participating once again.

Morning Survey – Cool Temps, Turtle Traps, and Frogs

After orientation, the herp team began their survey. The morning started cool, in the upper 50s, so a lower herp turnout was expected.

We began by checking turtle traps set earlier by Dr. Michael Finkler and his team in wetland areas. The first two traps were empty, but the next two yielded several adult painted turtles. Along the wetland perimeter, we also observed a northern leopard frog and a gray treefrog.

While walking the edge of another wetland, Yusnaviel spotted a watersnake, though it escaped before a photo could be taken. An unidentified turtle was also seen slipping off a log into the water.

Afternoon Highlights – Blanding’s Turtle & Salamanders

After lunch, we moved to another wetland to scan for basking turtles. Using binoculars, a Blanding’s turtle was spotted resting on a snag. We managed to get close enough to confirm the ID and take a few photos. More painted turtles were seen basking nearby, rounding out our turtle sightings for the day.

Later, we ventured to a deep woodland pool, where Dr. Finkler’s team supplied dipnets for amphibian larva collection. We successfully found and identified smallmouth salamander larvae.

Evening Finds & Final Thoughts

On the way back, we discovered a juvenile eastern garter snake with bright orange sides. Other Bioblitz participants later reported sightings of Dekay’s brown snakes, a gray ratsnake, and another garter snake.

Despite cooler weather limiting herp activity, the Bioblitz still provided valuable data and a great day of fieldwork. Many thanks to the Indiana Academy of Science and Little River Wetlands Project for hosting another fantastic event!
