Impact of global change and forest management on carbon sequestration in northern forested peatlands
Northern peatlands occupy approximately 4% of the global land surface and store about 30% of the global soil carbon (C). A compilation of C accumulation rates in northern peatlands indicated a long-term average rate of C accumulation of 24.1 g m 2 year 1 . However, several studies have indicated t...

Northern peatlands occupy approximately 4% of the global land surface and store about 30% of the global soil carbon (C).

Peatland development is related to precipitation and temperature, and climate change is expected to have an important impact on the C balance of this ecosystem.
