Fire has a role in ecosystem services; naturally produced wildfires are important for the sustainability of many terrestrial biomes and fire is one of nature's primary carbon-cycling mechanisms. Under a warming climate, it is likely that fire frequency and severity will increase…

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…
