Nestled on the picturesque north shore of Lake St. Francis, the Cooper Marsh Conservation Area is the proud Legacy of the late Mr. William Cooper Sr., a past Chair of the Raisin Region Conservation Authority. This cherished wetland is part of the larger Charlottenburgh Marsh - one of the most significant wetlands in all of Ontario. The RRCA actively maintains, protects, enhances and restores this natural area.

Follow the wetland boardwalks to explore the marsh and isolated ponds. Climb the viewing platforms and visit the viewing blinds to enjoy more than 130 species of birds that call Cooper Marsh their home. Drop by the Visitors Centre to take in taxidermy displays, view specimens under a microscope, and discuss your wildlife sightings with RRCA staff. Join one of the educational programs at Cooper Marsh run by the River Institute. Tours lead by RRCA staff, River Institute or volunteers may be offered when resources permit. 

Wetland birds that breed at Cooper Marsh Conservation Area include the Osprey, American Bittern, Virginia Rail, Sora, Green Heron, Wood Duck, Pied Billed Grebe, Black-Crowned Night Heron, Sandhill Cranes and the rare Least Bittern. The Marsh contains a wide variety of amphibians, turtles and fish. In the spring and fall migrations, many bird species visit the Marsh.

The Conservation Area and trails are open all year round. As the Cooper Marsh Conservation Area is a protected habitat, bicycles, dogs and motorized vehicles are prohibited on the trails.
