<\/p>\n\u201cOnly a small amount of the carbon that is released through combustion is the trees and the plants you are seeing above ground,\u201d he said. <\/p>\n
\t<\/p>\n
\u201cWildfires can burn off per square meter anywhere from half-a-kilogram to three-four-five kilos of carbon per square meter in a peatland.\u201d <\/p>\n
Olefeldt explained northern peatlands cover three per cent of the global land area, but they store about 25 per cent of the global soil carbon. That\u2019s because the plant material that accumulates in peatlands decomposes very slowly, which is the result of the waterlogged conditions where oxygen doesn\u2019t get under the water table. As plant material such as mosses accumulate year-by-year, carbon becomes captured and buried. <\/p>\n
\u201cThey are one of the largest carbon stores in the world, so they have provided this ecosystem service to us for a long time,\u201d Olefeldt said. <\/p>\n
\u201cThey had a cooling effect on the climate by taking carbon dioxide out of the atmosphere and storing it in the soil carbon, and ideally we would want that to continue to not revert into where peatlands are sources of carbon dioxide to the atmosphere which in turn creates this feedback loop where it actually amplifies the rate of warming.\u201d <\/p>\n
The rate which peatlands can become a source of wildfire emissions can be determined either through satellite observations or measurements by taking soil samples from the surface. Olefeldt noted burnt peatlands can become sources of emissions for several years and can also become a home to what\u2019s called zombie fires, which can smolder throughout the winter and then restart as an above ground wildfire in the spring. <\/p>\n
University of Saskatchewan Lecturer and Renewable Resource Management Program Coordinator Bryan Mood also spoke of the importance of peatlands as a carbon sink. He teaches an undergraduate course specifically focused on forest soils, which examines peatland environments, especially ones that are culturally significant to local communities. <\/p>\n
\u201cWhen we look at peatlands, they are actually a critical terrestrial carbon sink,\u201d Mood said, stating they store between 400 and 550 gigatons of carbon across the world. <\/p>\n
\u201cThose peatlands in terms of its ecosystem services to carbon have been well established as one of the world\u2019s largest terrestrial carbon sinks, but on the other side of it, those systems provide a lot of services to local communities through things like water filtration or different types of food and habitat for things like woodland caribou or a number other species and bird species as well, so very important in the general ecosystem of Saskatchewan.\u201d <\/p>\n
As wildfires destroy peatland, Mood said that means there are fewer areas people can use peatland and further pressure on areas where they can. Protecting those spaces, particularly for Indigenous people, is critical to maintaining traditional practices. <\/p>\n
