Mer Bleue

Mer Bleue Bog is a 33.43 km2 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 many species, including beaver, muskrat, waterfowl, and the rare spotted turtle. 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.
