A Timeline of Conservation

There is a remarkable history of conservation across this country, within the state of Wisconsin and closest to home, within Door County. The timeline below captures the arc and sweep of that history in summary form. 

The timeline is inspired by a new, two-part docuseries, Ridge and Swale, that tells the stories of those who fight for the land. 

Ridge and Swale is being released on Earth Day – Saturday, April 22 – with a special public showing at 7 pm at Door Community Auditorium, 3926 Hwy 42 in Fish Creek. Another public showing will take place Sunday, April 23, 3:30 pm, at Crossroads at Big Creek, 2041 Michigan St. in Sturgeon Bay. The docuseries will also be available for viewing online.Produced by Peninsula Filmworks, the series is made possible by its sponsors: the Peninsula Pulse, Destination Door County, The Ridges Sanctuary, Door County Medical Center and The Clearing.
