History and Background
Henry Cowles was a botanist from the University of Chicago. He published an article entitled "Ecological Relations of the Vegetation on Sand Dunes of Lake Michigan," in the Botanical Gazette in 1899 that established Cowles as the "father of plant ecology" in North America. The article brought international attention to the intricate ecosystems existing on the dunes.
The trail is a partnership between the National Park Service and the Town of Dune Acres.
