Overview Map

Chambers Island has always meant forests.


Hidden from the shore and the beaches, three thousand wooded acres and wetlands have existed for millennia. To safeguard the natural character of this extraordinary place, the Chambers Island community turned to the Door County Land Trust. Together they are seizing the opportunity to preserve these forests and save them from development, zoning re-evaluation and subdivision, which could mean loss of a pristine natural area forever.

Realizing the dream...

In just 2 ½ years after the Chambers Island Nature Preserve’s official start, 168 private individuals and foundations and governmental agencies have helped

  • Preserve almost 700 acres of forest land by early next year.
  • Save more than a mile of Lake Mackaysee shoreline, which means less pressure on such a small but precious asset.
  • Collect more than $1.6 million in private donations/pledges, and acquire another $1.2 million in state and federal matching funds.
  • Conduct summer exploration hikes/talks. We are all just beginning to appreciate the more than 170 bird species and the 350 plant species on Chambers - several of which are rare or threatened.
  • Preserve the only muskeg found in the islands of Green Bay and the Grand Traverse Island Chain.
  • Fight invasive species like Phragmites, garlic mustard and gypsy moths.

But we have a new challenge in getting to the finish line.

  • The Chambers Island Nature Preserve is no longer eligible for matching funds from the Wisconsin Knowles-Nelson Stewardship Fund, which now prioritizes land near population centers for recreational purposes.
  • The Door County Land Trust team is seeking other possible public funding to preserve/restore Great Lakes wetlands to help make up for the loss of state funds. We are identifying foundations unrelated to Chambers but supporting conservation that may help us.
  • And we need continued help from all of you!
