Burns Bog

The Burns Bog is the largest domed peat bog on the west coast of North America. It covers an area of about 40 square kilometres (15 square miles) and occupies a quarter of Delta, British Columbia, about 25 km (16 mi) southeast of downtown Vancouver, and is bounded by BC Highway 10 on its south, the Annacis Highway on its east, and River Road, along the South Arm of the Fraser River on its northwest. It is named after the former owner, Patrick Burns of Burns Meat Packaging. Its indigenous name is Maqwum, or in proper Hunquminum orthography, Ma?qwem . The word simply means "bog" but may refer to a specific plant growing in the location as well.

The bog's ecosystem sustains a wide variety of flora and fauna, including 24 species of mammal and 150 bird species. Numerous zoning codes have been enacted to protect the bog from development and retain its original state in hopes of preservation for future generations. The bog is thought to be a major regulator of the region's climate, since there is no drainage and all the rain fall is ultimately evaporated. Highway 91 and flood control measures for nearby farms have cut off periodic flooding and drainage that previously fed into the bog. The Burns Bog has black bears roaming freely.

According to Environment Canada and other groups, the bog ecosystem is under threat from the proposed South Fraser Perimeter Road.

The southern part of the bog contains a landfill for the city of Vancouver.
