Mer Bleue Conservation Area
The Mer Bleue Conservation Area is a 33.43 km2 (12.91 sq mi) protected area east of Ottawa in Eastern Ontario, Canada. Its main feature is a sphagnum bog that is situated in an ancient channel of the Ottawa River and is a remarkable boreal-like ecosystem normally not found this far south. Stunted black spruce, tamarack, bog rosemary, blueberry, and cottongrass are some of the unusual species that have adapted to the acidic waters of the bog.
The area provides habitat for a large number of species, including beaver, muskrat, waterfowl, and the rare spotted turtle (Clemmys guttata). A 1.2 km boardwalk allows visitors to explore a section of the bog. There are hiking trails that follow raised areas along the edges of the bog and cross-country skiing trails for use in winter. The conservation area is managed by the National Capital Commission.
The value of this unique wetland was not always recognized. During World War II, the Royal Canadian Air Force used this area for bombing practice. Now, this area has been designated as a Wetland of International Significance under the Ramsar Convention since October 1995.
The name "Mer Bleue" (French, meaning "blue sea") is thought to describe the bog's appearance when it is covered in morning fog.
