By suppressing all wildfires and incessantly burning fossil fuels, humans have upset the role that fire has historically played in providing ecological balance. We need to rethink our view of fire and accept its presence by changing how we manage…

Wildfires can result in significant social, environmental and economic losses. Fires in which dynamic fire behaviours (DFBs) occur contribute disproportionately to damage statistics. Little quantitative data on the frequency at which DFBs occur…

Researchers are increasingly examining patterns and drivers of postfire forest recovery amid growing concern that climate change and intensifying fires will trigger ecosystem transformations. Diminished seed availability and postfire drought have…
