Increasingly frequent and intense wildfires threaten to push ecosystems beyond their ecological thresholds. Fire‐adapted forests can be vulnerable to ecosystem conversion under shortening fire‐return intervals. To evaluate the impacts of fire regime change, we contrasted Eucalyptus forests that retained canopy cover under tolerable regimes (reference forests) with alternative states of markedly reduced canopy. These alternativ...
