A forgotten 30-year forest experiment just delivered a huge surprise
A long-term forestry experiment in Victoria, Australia, has provided new insights into how mountain ash forests regenerate after logging. The study compared various silvicultural methods, finding that clearfelling remains the most effective approach for regeneration in these specific forests.
Why it matters
This research provides evidence-based data to help resolve long-standing debates between conservationists and the timber industry regarding sustainable forest management.
What's the best way to manage a forest? Australians have argued about this for decades. The debate is often framed as binary: do we protect forests entirely, or harvest trees to support local economies and communities?
The reality is more interesting, as our new research on a long-forgotten experiment in Victoria's mountain ash forests reveals.
Since the 1970s, scientists and the public have questioned the use of clearfell logging - where all trees in a block of forest are cut down. Conservationists argued it destroys habitat for rare species and reduces the forests' ecological value. Foresters said mountain ash is adapted to catastrophic bushfires, and clearfelling is the forestry equivalent .
The argument was heated and the polarization unhelpful. But the underlying questions about the impacts of clearfelling, and how they compared to less intensive forestry options, remained unresolved.
