Fowler’s Toads are endangered in Ontario. Their main threat is habitat loss and degradation. The loss and degradation of dunes, beaches, and wetlands as a result of shoreline development and recreation use, reduces areas for breeding, hiding, burrowing, and hibernating.
Fowler’s Toads are primarily nocturnal and forage in the evenings for a wide range of insects, particularly ants and beetles. Like the American Toad, toxins and noxious secretions that deter predators are produced by glands in the toad’s skin. During the day, individuals burrow into the upper beach and dunes or hide under driftwood.
