Abstract

Abstract Climate-induced changes in fire regimes in south east Australia have the potential to alter ecosystem and ecohydrological resilience in native Eucalyptus forests. A drier, hotter climate is triggering short-return, high-intensity, mega-fire events across Australia. In Victoria, over 189,000 ha of fire-sensitive, Eucalyptus regnans and Eucalyptus delegatensis forests have been burned two or more times within the past 18-years. Under these multiple burn conditions, fire-sensitive forests are highly vulnerable to ecological tipping points. Naturally occurring E. regnans is a dominant species in the higher rainfall regions of south east Australia. However, short interval fires (15-20 y..
