Canada: Sphagnum peat moss production and sustainability
In Canada, these wetlands appeared after glaciers melted and water collected in shallow depressions on poorly drained soils under cool, moist and oxygen poor conditions. This environment has limited bacterial action due to cool temperatures. Therefore, the rate of sphagnum moss plant growth exceeds the rate of decomposition. Over time, the slow decomposing moss debris accumulated, forming a peat deposit that in some places can exceed 6 meters in depth. The rate at which peat accumulates in Canadian peatlands ranges from 0.5 to 1 mm per year.
