The summer of 2021-22 will be remembered for the extraordinarily destructive flooding across eastern Australia. At the same time, however, western Tasmania was experiencing extreme drought, with some areas receiving their lowest rainfall on record.
This drought fits an observed drying trend across the state, which will worsen due to climate change. This is very bad news for the ancient wilderness in the state’s World Heritage Area, where the lineage of some tree species stretch back 150 million years to the supercontinent Gondwana.
The drying trend has seen a steady increase in bushfires ignited by lightning, imperilling the survival of Tasmania’s Gondwanan legacy, and raising profound fire management challenges. Indeed, climate change means we’re on a learning curve, and the usual practices of managing fire are no longer necessarily fit for purpose.
