Once again, we are hearing that Australia’s forests are being ‘reshaped’ by climate change as droughts, heat waves, rising temperatures and bushfires drive ecosystems towards collapse.
Ecologists have long predicted that climate change would have major consequences for Australia’s forests. Now they believe those impacts are already unfolding. Mountain Journal has often reported on this, for instance:
- In Tasmania, research has confirmed the trend towards more extreme fire seasons. It suggests that we reached a ‘tipping point’ sometime around the year 2000 and that, since then, there has been an increase in the number of lightning-caused fires and an increase in the average size of the fires
- Fires have decimated some populations of Alpine Ash and Snow Gum
- Mountain Ash forests could collapse as a result of climate change
A new report, covered in The Guardian describes one of the processes driving the change, called the ‘interval squeeze’.
