National Park Service Acadia U.S. Department of the Interior Acadia National Park

Mammals, Amphibians, and Reptiles

Acadia National Park contains a variety of natural habitats that provide homes for many different animal species. The location of the park on the coast and the diversity of habitats explains this species richness. The size of these habitats and their separation from other habitats or larger natural habitats, however, limits the types of animals that are found here. Small animals adapted to smaller habitats are therefore more common, unlike the large mammals such as black bears and moose that require large areas and are rarely observed. The quieter and more patient you are, the greater your chances of finding and observing any animal, regardless of size. If you have any unusual wildlife sightings while you are exploring the park, please fill out a wildlife observation card at the visitor center, nature center, campgrounds, or park headquarters.
