Tree Frog

There are 20 species of amphibians that have been found within the Lakeshore. These include blue-spotted, spotted, four-toed and red-backed salamanders; mudpuppies; central newts; eastern American and Fowler’s toads; Blanchard’s cricket frogs; spring peepers; gray tree frogs; bullfrogs; and western chorus, green, Pickerel, northern leopard, and eastern wood frogs. The various species will serenade visitors from early spring into mid-summer. Areas near small lakes and marshes or moist areas in the hardwood forests are the best spots for listening to their calls and for the opportunity to see an amphibian.
