Burning Season Begins: Habitats at Risk in East Gippsland - Part 1 Colquhoun Forest, Lake Tyers.
Walking along Blackfellow's Arm in Lake Tyers State Park a few months ago, you might have done what a GECO volunteer did: stopped in their tracks at bird calls they had never heard before. Through a clump of she-oaks, dark shapes huddled in a branch. The phone camera wasn't good enough to be certain.
The recording was sent to the . Their verdict: almost certainly a trio of Glossy Black Cockatoos, two adults and a fledgling.
It was a first encounter with one of Victoria's most threatened and specialised birds. A 2025 FOI request obtained by Gippsland Environment Group estimated only around 100 Glossy Black Cockatoos remaining between Colquhoun Forest and the NSW border. Local naturalists think the number may be even lower, with fewer than 50 birds believed to occur between Lakes Entrance and the Snowy River. The Black Summer fires destroyed nearly two-thirds of their Victorian habitat, and the birds that survived are now almost entirely dependent on small, unburnt coastal she-oak stands along this narrow stretch of East Gippsland coast.
Forest Fire Management Victoria is planning to burn through the heart of it this season.
Three burns are of immediate concern in this area. The Colquhoun burn (GP-TBO-NOW-0504) covers 1,373 hectares of forest along the Mississippi Creek trail, known habitat for Glossy Black Cockatoos, Greater Gliders, Yellow-bellied Gliders, Masked and Powerful Owls, Gang-gang Cockatoos, and Grey-headed Flying-foxes. The S***f Gully burn near Nowa Nowa (GP-TBO-NOW-0641) covers 1,197 hectares around 6 kilometres south of Nowa Nowa, in the same coastal forest corridor where that trio of Glossies was recorded at Blackfellow's Arm. And the Trident Arm burn (GP-TBO-NOW-0298) covers 402 hectares around 10 kilometres south-southeast of Nowa Nowa, in a patch of old-growth forest with almost no recorded burn history. Of the three burns, only 4 hectares of the Trident Arm area has ever been treated, which tells you something important: this is some of the most ecologically intact country left in the region, and it is on the burn schedule.
All three burns are planned for autumn, which overlaps directly with the Glossy Black Cockatoo's breeding season. Nestlings in hollows cannot escape. Adults lose their food source at the moment they are feeding chicks.
The Glossy Black Cockatoo feeds almost exclusively on the seeds of Black She-oak trees. Fire kills these trees outright. Even a low-intensity burn causes the cones to shed their seeds before the birds can reach them. For a population this small, confined to this narrow corridor, losing feeding habitat across any one of these burns is not a minor disturbance. It is a serious risk to the species' survival in Victoria.
The ecological cost extends beyond the Glossies. A DEECA-funded study by Bluff found that hollow-bearing trees in planned burn areas were 28 times more likely to collapse than in unburnt forest, with around one in four collapsing after a single burn. These are trees that take up to 200 years to form hollows large enough for a Greater Glider. Roadside clearing by contractors is already underway ahead of these burns, and the damage to habitat is cumulative and largely irreversible.
For old-growth forest like Trident Arm, which has largely escaped fire for long enough to develop the structural complexity that threatened species depend on, a single planned burn does not just set back recovery. It destroys what took generations to build, on a management rationale that the science increasingly does not support.
GECO is calling on Forest Fire Management Victoria and the Minister for Environment to:
- Immediately halt the Colquhoun burn (GP-TBO-NOW-0504), the S***f Gully burn (GP-TBO-NOW-0641), and the Trident Arm burn (GP-TBO-NOW-0298) pending proper ecological assessment.
- Refer all three burns to the Federal Department for assessment under the EPBC Act, given the likely significant impact on nationally listed threatened species including the Glossy Black Cockatoo, Greater Glider, and Powerful Owl.
- Publicly release the ecological risk assessments for all three burns, including what species surveys have been conducted, how threatened species impacts have been assessed, and what safeguards are proposed.
No burn of this scale, in habitat this important, should proceed without that information being publicly available.
