The area surrounding the Great Lakes is a haven for temperate terrestrial orchids. Among the distinct geological features is the Ridges Sanctuary at Bailey's Harbor, Door County, Wisconsin. A survey of the Ridges shows that it is home to 28 species of North American native terrestrial orchids. A combination of objective fieldwork and demographic research is used to create an orchid habitat management plan. An educational component for the project is included to discourage wild collection of native orchids by visitors to the Ridges Sanctuary.
