Zetterberg Preserve at Point Betsie

Michigan

Point Betsie contains diverse natural communities, including wetlands, dunes, beaches, and forests.

Why Is This Preserve Significant?

The dunes at Pt. Betsie are part of the largest freshwater dune system in the world, which covers 275,000 acres of Lake Michigan shoreline. The Pt. Betsie dunes provide critical habitat for rare species, including Pitcher’s thistle. They have also been identified as a potential nesting site for piping plover as the population of this endangered species recovers. The Nature Conservancy works with partners through the Michigan Dune Alliance to conserve this rare coastal ecosystem.

What Can I See Here?

Point Betsie is a dynamic mosaic of shifting sand dunes, wetlands, boreal forest and sandy Lake Michigan beaches constantly battered by wind, ice, waves and currents moving along the shore of the lake. This globally imperiled open dune habitat provides a place where threatened species such as Pitcher’s thistle, fascicled broomrape and the Lake Huron locust can thrive.

Dune vegetation includes marram grass, beach pea and hoary puccoon with forested islands of balsam fir, paper birch, red oak and creeping juniper. Peaceful ponds among the dunes swell and shrink in sync with water levels in Lake Michigan, attracting migrating birds such as the semipalmated plover. Cedar waxwings flit through pockets of forest while spotted sandpiper and killdeer scurry over the sand. 

Point Betsie became a preserve through the generosity of Steve and Connie Zetterberg. In 1988 the Zetterbergs donated the original 71 acres of virgin sand dunes which became the Zetterberg Preserve at Point Betsie—property that had been in their family for generations. After having been preserved by the Zetterberg family, Point Betsie is now maintained by TNC and cherished by generations of Michiganians.

For your safety and to protect this fragile ecosystem, please STAY OFF the dunes. Consider a hike along the shoreline instead of through the preserve to prevent dune erosion. Please note the photo of the state and globally threatened Pitcher’s thistle to help you avoid trampling plants.

Preserve is adjacent to the Point Betsie Lighthouse, which is open for tours Memorial Day to Columbus Day. The beach is not part of the Preserve. Respect private landowners that live adjacent to the Preserve by not trespassing.

The rare Pitcher’s thistle blooms in July with cream-colored flowers. Point Betsie also offers excellent bird watching opportunities during the spring and fall migrations, which are in May and late August through September respectively.

Natural hazards to be aware of include poison ivy and leafy spurge, which can cause skin irritations. Walking the sand dunes of this preserve is strenuous, and there are dangerous lake currents offshore. Be sure to bring plenty of water with you when you visit.
