What happens to carbon after a forest fire?
Most of us think of carbon being released into the atmosphere when forests burn. But some of it takes a different path. A portion is transformed into pyrogenic carbon, a stable form of carbon that can remain stored in soils and lake sediments for hundreds or even thousands of years.
In a new PhD project at SLU, Wint Wah Phoo is investigating how pyrogenic carbon is transported from burned forests to nearby lakes and how much of it is ultimately stored in sediments. The research combines fieldwork at prescribed burn sites with sediment studies to better understand a potentially overlooked part of the global carbon cycle.
The findings could improve climate models and carbon accounting while providing new insights into the role of fires in long-term carbon storage.
