"Landscapes that have escaped fire for decades or centuries tend to harbour
vital structures for wildlife, such as tree hollows and large logs. But these
“long unburnt” habitats can be eliminated by a single blaze.
The pattern of fire most commonly experienced within an ecosystem is known as
the fire regime. This includes aspects such as fire frequency, season,
intensity, size and shape.
Fire regimes are changing across the globe, stoked by climate and land-use
change. Recent megafires in Australia, Brazil, Canada and United States
epitomise the dire consequences of shifting fire regimes for humanity and
biodiversity alike.
We wanted to find out how Australian fire regimes are changing and what this
means for biodiversity.
In our new research, we analysed the past four decades of fires across southern
Australia. We found fires are becoming more frequent in many of the areas most
crucial for protecting threatened wildlife. Long unburnt habitat is
disappearing faster than ever."
