Purpose and significance of Isle Royale National Park

The purpose of Isle Royale National Park is to:

Preserve and protect the park's wilderness character for use and enjoyment by present and future generations.

Preserve and protect the park's cultural and natural resources and ecological processes.

Provide opportunities for recreational uses and experiences that are compatible with the preservation of the park's wilderness character and park resources.

Provide park-related educational and interpretive opportunities for the public.

Provide opportunities for scientific study of ecosystem components and processes, including human influences and use, and share the findings with the public.

Isle Royale National Park is significant because:

This maritime park, an international biosphere reserve, encompasses a remote and primitive wilderness archipelago isolated by the size and power of Lake Superior.

Isle Royale is world renowned for its long-term wolf/moose predator/prey study. The park offers outstanding possibilities for research in a remote relatively simple ecosystem where overt human influences are limited.

Park waters contains the most productive native fishery and genetically diverse lake trout populations in Lake Superior.

A dark shinning rock outcrop glistens from the rain.

The last glacier receded from this area about 10,000 years ago. As the glaciers melted, they formed a huge lake which permanently separated Isle Royale from the mainland. Today, the coolness of the big lake (Lake Superior) creates a climate in which artic plant species grow.
