Shortly after Michigan joined the American Tree Farm program in 1949, Carlotta Ewing
had the Wilderness certified as a state-sanctioned Tree Farm. She and her husband
A.E. Ewing in 1921 bought 199 acres of wooded duneland along the lakeshore and
named it the Wilderness. Carlotta earned the Tree Farm designation because of her
environmental concerns and conscientious forest management since the beginning of
the Wilderness. The sign, visible from Lakeshore Drive for years, was posted near the
entrance. Today it is stored in a Wilderness cottage. Thanks to Marilyn Green for the
photograph.
In 2024, Ottawa County had 22 Tree Farms with an aggregate of 1,339 acres.
