A Landscape in Peril: The Snow Gum’s Fight for Survival
The Australian Alps, a majestic expanse of rolling mountains and pristine landscapes, now bear a somber sheen. Once vibrant with the rich greens and striking bark of Snow Gums (Eucalyptus pauciflora), these regions are increasingly haunted by the silver skeletons of dead trees.
With climate change, invasive species, and bushfires wreaking havoc, the Snow Gum is teetering on the brink of extinction. Yet, hope remains as conservationists, scientists, and communities rally to save this iconic species.
A Symbol of the Australian Bush
The Snow Gum is synonymous with Australia’s alpine landscapes. Its smooth, multicolored bark and ability to thrive in freezing conditions make it a vital part of these ecosystems. Beyond its aesthetic appeal, the Snow Gum plays a crucial role in supporting alpine wildlife, including birds, insects, and marsupials like the endangered mountain pygmy possum.
However, its resilience is being pushed to the limit. Only 1 percent of healthy, unburnt Snow Gum woodland remains in Victoria, hightlighting the urgency of action.

The Snow Gum Summit: A Call to Action
To address this crisis, Friends of the Earth Melbourne will host the inaugural Snow Gum Summit from 14 to 16 February 2025 at Dinner Plain Village in Victoria’s high country. This event aims to unite leading academics, outdoor groups, First Nations custodians, land managers, and community associations to collaborate on interventions to halt the Snow Gum’s decline.
The summit’s agenda is ambitious yet critical:
- Expert Presentations: Leading researchers will shed light on the threats facing Snow Gums, including dieback caused by the Phoracantha longhorn beetle and the impacts of climate change.
- Workshops and Discussions: Attendees will brainstorm actionable strategies to protect existing habitats and restore degraded areas.
- Guided Bush Walks: Participants will visit special remnants of old Snow Gum forests on the Bogong High Plains and Mt Wills, experiencing firsthand the beauty and fragility of these ecosystems.
With tickets capped at 80 attendees, the Snow Gum Summit aims to make a significant impact while keeping discussions intimate and productive.
The Threats Facing Snow Gums
1. Climate Change
Warming temperatures and reduced snow cover are drastically altering the Snow Gum’s habitat. Prolonged droughts and more frequent bushfires add to the stress, often overwhelming the tree’s natural resilience.
2. Dieback Disease
A more immediate and visible threat is dieback, caused by Phoracantha beetles. These pests bore into trees, disrupting their vascular systems and leaving them vulnerable to secondary infections. The beetle population has exploded due to changing environmental conditions, exacerbating the problem.
3. Bushfires
While Snow Gums are adapted to recover from occasional fires, the increasing intensity and frequency of megafires, such as the 2019-2020 Black Summer, are preventing regeneration. Seedlings and younger trees often perish before reaching maturity.
4. Human Activities
Tourism, ski resort development, and land clearing for agriculture have reduced the extent of Snow Gum habitats. These activities also increase the risk of introducing diseases and pests.
Conservation Efforts and How to Help
Efforts to save the Snow Gum are growing, but success depends on widespread support. Here’s how individuals and communities can contribute:
Support Conservation Groups
Organizations like Friends of the Earth Melbourne, Greening Australia, and the NSW Biodiversity Conservation Trust are at the forefront of protecting Snow Gums. Volunteering, donating, or joining their initiatives can make a difference.
Advocate for Climate Action
Reducing carbon emissions and supporting renewable energy policies are crucial to mitigating climate change, a primary threat to alpine ecosystems.
Participate in Reforestation Projects
Planting native trees in fire-affected or degraded areas helps restore habitats. Reforestation Australia and local Landcare groups often run community planting days.
Combat Dieback
Report signs of dieback to local authorities or conservation groups. Avoid transporting firewood or timber between locations to prevent the spread of Phoracantha beetles.
Practice Responsible Tourism
When visiting alpine regions, stick to designated trails, avoid disturbing vegetation, and adhere to fire safety guidelines.
Educate and Engage
Raising awareness about the Snow Gum’s plight and engaging in citizen science programs can amplify conservation efforts. Apps like iNaturalist allow individuals to contribute valuable data on tree health and distribution.
A Fight for the Future
The Snow Gum’s decline is a stark reminder of the fragility of Australia’s unique ecosystems. Yet, the upcoming Snow Gum Summit exemplifies the collective determination to ensure this iconic tree remains a living symbol of the alpine landscape. Through education, collaboration, and direct action, there is hope to turn the tide and secure a future where Snow Gums thrive once more.
As the landscape of the Australian Alps changes, so too must our approach to conservation. The Snow Gum’s survival depends on us all.
