Discover the Mer Bleue bog!

The Mer Bleue Bog in Ottawa is one of the most outstanding natural features of the Greenbelt. The 3,500-hectare conservation area has a northern eco-system more typical of the Arctic than Ottawa Valley. At Mer Bleue you will find interpretive boardwalks, sand ridges, cross-country ski trails and forests. Mer Bleue is the largest bog and natural area in Canada’s Capital Region and the second largest bog in southern Ontario.

A Northern Boreal Landscape

Mer Bleue provides a unique opportunity to see a northern boreal landscape minutes from a large city. This 7,700-year-old bog provides habitat to many species of regionally rare and significant plants, birds and other wildlife. It also supports plants and wildlife populations that are typical of northern boreal bogs.

The Amazing Mer Bleue!

Mer Bleue bog plays an important part in stabilizing the climate. It is one of the most studied bogs in the world. A permanent research station at the centre of the bog measures the amount of carbon dioxide and methane that is released by the wetland. For more information, read about the Peatland Carbon Study.

Mer Bleue is recognized in Canada and abroad. It is a:

  • Wetland of International Importance under the Ramsar Convention on Wetlands
  • Provincially Significant Wetland
  • Provincially Significant Life and Earth Science Area of Natural and Scientific Interest (ANSI).
