Biomass burning is a common force in much of the developing tropical world and has wide-ranging environmental impacts. Fire is an important component in tropical deforestation and is often used to clear broad expanses of land for shifting agriculture, dispose of crop residue,…

This paper's title - "Can we restore the fire process? What awaits us if we don't?" - represents an ecologist's view of the world. I submit that this view is unrealistic. The first clause uses the term "restore" which implies reestablishing the fire process of the past. The…
