Harbor Island National Wildlife Refuge, National Wildlife Refuge on an island in Potagannissing Bay, Michigan
Harbor Island National Wildlife Refuge is a 695-acre protected area on a horseshoe-shaped island in Potagannissing Bay near Drummond Island. The landscape contains forests, wetlands, and natural shorelines that provide diverse habitats for wildlife.
The island was transferred from The Nature Conservancy to the U.S. Fish and Wildlife Service in 1983 to establish a protected natural area. This transition marked the start of formal management and conservation efforts to preserve the landscape and wildlife.
The refuge draws birdwatchers and nature enthusiasts who come to observe rare species like bald eagles and loons in their natural habitat. People value the island as a place where wildlife thrives without human interference.
Visitors need a boat to reach the island since there are no bridges from the mainland; the nearest launch points are Drummond Island Yacht Haven and Township Park. Weather conditions can change quickly on the water, so it is wise to check forecasts and plan boat trips accordingly.
The island contains a mature white pine stand on the eastern shore and an old-growth oak forest on the north side. These distinct forest sections offer visitors examples of the different tree communities that developed naturally in northern Michigan.
