White tailed deer, coyote, porcupine, skunk, beaver and thirteen-lined ground squirrels are some of the more common sightings. Prairie pocket gophers are rarely seen but are evident because of their prominent tunnel activities amongst the historic village sites. A large number of birds can be seen on a walk in the park.
