Short- and long-term effects of fire on carbon in US dry temperate forest systems
Matthew D. Hurteau, Matthew L. Brooks
2011, BioScience (61) 139-146
Forests sequester carbon from the atmosphere, and in so doing can mitigate the effects of climate change. Fire is a natural disturbance process in many forest systems that releases carbon back to the atmosphere. In dry temperate forests, fires historically burned with greater frequency and lower severity than they do...
