The only species intimately associated with these wetlands are the tiger salamander, leopard frog, and chorus frog. Salamander larvae at high densities are an important component in the energy flow of the wetlands they inhabit. Aquatic birds that normally feed on fish also feed on larval salamanders.
Leopard frogs have an immense range in North America.
On the Dakota prairies, these frogs seem to prefer temporary and seasonal wetlands for courtship activities, but lay most of their eggs in semipermanent wetlands where the tadpoles require about 3 months to metamorphose into adults. The diminutive chorus frog is found over most of North America. The frogs congregate to breed in the early spring in seasonal and semipermanent wetlands. After breeding, they wander away from water bodies, but still require damp places to avoid desiccation.
