A northern boreal landscape

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

Climate research

The 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.
