context_page_description: Burns Bog is an ombrotrophic peat bog located in Delta, British Columbia, Canada. It is the largest raised peat bog and the largest undeveloped urban land mass on the West Coast of the Americas. Burns Bog was originally 10,000–12,000 acres before development. Currently, only 3,500 hectares remain of the bog.
  Burns Bog is habitat to more than 300 plant and animal species, and 175 bird species. Some of these animals are listed as endangered or vulnerable under the BC Provincial Government Species at-risk designations. The bog is also a major migratory stopover for various bird species on the Pacific Flyway.
  Burns Bog regulates water as well. The bog prevents flooding, maintains cool water temperatures in nearby rivers, holds water, and releases water in dry conditions. Burns Bog is an estuarine bog since it is situated at the mouth of the Fraser River and next to the Pacific Ocean. It is the only estuarine raised peat bog formed in a marine west coast climate.
context_section_description: The major characteristics of Burns Bog is that it is wet, acidic, and peat-forming. It is a wetland ecosystem with a diverse array of plant, animal, and insect species. A major component of Burns Bog is sphagnum moss, which is able to hold about 30 times its weight in water. Sphagnum moss can grow under wet and acidic conditions and it is the major building block of peat in Burns Bog. 
  Breakdown of organic matter in the bog progresses slowly due to low oxygen content and high acidity of the water.
  Burns Bog plays a major role in climate regulation. It helps to maintain the health of nearby creeks, which are critical salmon-bearing sites. The peat in the bog does this by cooling and filtering rainwater that comes in. This water then leaches into these salmon-bearing creeks.
  Burns Bog is also a major carbon sink. Since organic matter decomposes at a very slow rate in the bog, carbon stays in the bog. High acidity and the waterlogged conditions of peatlands such as Burns Bog prevent complete decomposition of fixed carbon. This prevents the carbon from escaping into the atmosphere. European scientists state that an area of peatland the size of a soccer field stores as much carbon as would be generated by driving a family car around the world three times.
