In 2013, many regenerating stands of Alpine Ash in Victoria’s Alpine National Park were killed by repeated wildfires over 10 years. The young trees had no seed capsules and did not resprout; most trees died and few seedlings replaced them.

To replace the dead stands, Alpine Ash seeds were aerially sown over 1,800 hectares. If these stands continue to be burnt in repeated fires, seeds will have to be sown again. At that time, should we sow Alpine Ash or another eucalypt that can resprout after wildfires, or perhaps a mix?

As climate change intensifies, there will be more days of extreme fire weather. For this reason, many areas are expected to become less suitable for Alpine Ash, and for other species. The burnt stands of Alpine Ash highlight a dilemma that we and our children will face more and more often as climate change intensifies.

To what extent should we try to save the species and ecosystems that currently occur in a particular area, and at what stage should we accept, or even assist, new plants and animals that are more suited to the new climate?

There are many things we can all do to help nature adapt to a new climate, but there are limits. As climate change intensifies, we will have no choice but to accept more changes in natural areas than we are accustomed to, or – if we choose to prevent changes – to accept more interventions. Ultimately, both options may catalyse new ways of thinking and working.

To suggest that we will need to “accept” more changes in natural areas does not imply that we should try to “like” these changes. We may not. Yet, we cannot disparage the new native species and altered natural areas that flourish under the new climate.

Our children will enjoy altered natural areas, like the forests of the Central Highlands, for many of the reasons that we do: as places to seek respite, holiday with friends and family, and enjoy nature. Even though those places have changed.

By accepting that natural areas will continue to change under a new climate, by intervening to curtail the changes we do not accept, and by respecting altered ecosystems as they adapt to the new climate, we ensure we do not devalue the natural places that our children and grandchildren will cherish, love and work to conserve.

To help nature adapt to a new climate

  • We are accepting that natural areas will change as climate change intensifies.
  • We are acknowledging the value of the new ecosystems that climate change will create.
  • We are making sure that we do not denigrate the new native species and the altered ecosystems that climate change will deliver.
