Alcoa Mine Rehabilitation Failure

05 December 2024

US bauxite miner Alcoa’s mine site rehabilitation efforts in the Northern Jarrah Forests have been slammed by Western Australia’s leading scientists and conservation organisations.

A recent independent scientific assessment has given Alcoa only 2-stars for its bauxite mine site rehabilitation in the Northern Jarrah Forest (NJF). This is well below the 5-star rating the company and government agree is needed to restore a self-sustaining forest ecosystem. The report has been brought together with other evidence of forest rehabilitation failure by Alcoa and fellow bauxite miner South32 in a fact sheet published by the End Forest Mining campaign.

The document highlights that Western Australians have been sold a lie that rehabilitation is working. Returning mining pits to a functional Jarrah forest is not possible due to the removal of the essential bauxitic substrate on which these ancient forests have evolved.

One of the report’s authors, Professor Kingsley Dixon stated:

“The scientific community is clear: it is not a lack of knowledge but a lack of ecological fabric to create a Jarrah forest that is the issue”

Compared to unmined forests, 20-year-old rehabilitation has fewer plant species, more weeds, Jarrah trees forking closer to the ground and fewer Marri trees which are important for fauna habitat and ecological resilience.

To date none of Alcoa’s rehabilitation has been signed off by the WA Government as successfully completed in 60 years of mining.

“The Cook government must face the facts and halt bauxite mining expansions.

The forest that remains must be protected if we want to have safe drinking water, climate, nature and continued access to Perth residents’ favourite weekend destination.”

Write to the Premier, the Ministers for Environment, Mines and Water and your local MPs to ensure the Cook Government knows that Western Australians want an end to the irreversible damage from mining forests for bauxite.

Protect the tingles from prescribed burning, for good

Tingles are a large, ancient tree species that are only found in a small area in WA’s Southwest, close to Walpole. They can live for more than 400 years, reach heights over 55 metres and have the largest base of any eucalypt, and provide critical habitat to many threatened plants and animals. They are vulnerable to frequent fire.

In December 2024, Giants East, a tingle forest block in the famed Valley of the Giants, was torched as part of the Department of Biodiversity, Conservation and Attractions (DBCA)’s prescribed burning program. 

More than 100 giant trees collapsed in the intense burn, with flames reaching the tops of many trees in one of the worst outcomes seen by WA’s prescribed burning program.

After persistent community action, three tingle-karri blocks,  Nornalup, Coalmine and Mount Clare received a reprieve at the end of 2025 and were removed from the burn plan until July 2026. 

But these blocks, and other tingle forests, aren’t safe forever. They could be on the burn plan for 2026-27. There must be a commitment from the WA Government to permanently protect tingles from prescribed burning and revise how fire is managed in these areas.

Over time, tingle forests self-thin and become naturally less flammable. Left unburnt, they are less of a fire risk than forests burnt in the last 30 years. 

In a drying climate that is increasingly prone to bushfires, it’s important to be bushfire ready, but prescribed burning shouldn’t be the only tool in our bushfire prevention kit. It is vital that the Southwest’s prescribed burning practices reflect current science and a changed climate, and funding is directed towards rapid detection and suppression of bushfires.

It is of the highest priority that the tingles are protected from fire not just in this burn plan, but for good.
