Turning the tide on extinctions – priority actions on invasive species for the next Australian Government

A queen ant flies into a shipping container. A pregnant gecko slides into a package. A beetle bores into wooden furniture. Fungal spores waft onto a tourist’s boots. A cactus fancier places an online order. 

One trivial action – human or non-human, accidental or intended – can end up costing Australia billions. It can wipe out species. Degrade bushland. Make cities less liveable. Destroy crops and livestock. Harm people and pets. Turn diverse ecosystems into depauperate monocultures.

That is why Australia’s governments of all stripes have, despite setbacks, maintained the eradication program for red imported fire ants over the past 24 years. It’s why the Australian Government has committed >$100 million to prepare for the likely arrival of H5 bird flu. And it’s why thousands of trees have been felled in Perth in pursuit of a tiny fungus-farming beetle.

Over the past 200 years, the consequences of biological invasions have been catastrophic for Australia. Measured in species – at least 60 lost, including 6 this century, and at least another 60 likely in the next 10–20 years. Measured in dollars – $24.5 billion a year in measurable costs. Measured in heartbreak? For 2 in every 3 Australians, stopping extinctions is ‘very important’.

New invaders continue to establish. Established species continue to spread. The list of species heading to extinction due to invasive species continues to lengthen. Numerous reports warn of growing pressures on Australia’s border biosecurity system. Numerous studies, including the latest state of the environment report, document escalating damage. Australia’s invasion debt is huge. The extinction crisis is real. 

BUT ON THE SIDE OF HOPE: Many dedicated people, inside government and out, are working to reverse these trends. The Australian Government has committed to no new extinctions. Australia has some of the world’s best biosecurity experts, invasion biologists, innovators and on-ground practitioners. Passionate land managers and community groups are pouring in an enormous effort to undo the damage. The creation of island and mainland havens has averted extinctions. Transformative technologies are emerging.

Save the Snowies

The NSW government is one step away from allowing aerial control of feral horses in Kosciuszko National Park. This is huge news and a crucial step for our threatened native wildlife and the fragile alpine ecosystems they call home.

Dear Project Team,

[YOUR PERSONALISED MESSAGE WILL APPEAR HERE.] 

I support the amendment to the Kosciuszko National Park Wild Horse Heritage Management Plan to allow our incredible National Parks staff to use aerial shooting as one method to rapidly reduce feral horse numbers. I want to see feral horse numbers urgently reduced in order to save the national park and our native wildlife that live there.

The current approach is not solving the problem. Feral horse numbers have rapidly increased in Kosciuszko National Park to around 18,000, a 30% jump in just the past 2 years. With the population so high, thousands of feral horses need to be removed annually to reduce numbers and stop our National Park becoming a horse paddock. Aerial shooting, undertaken humanely and safely by professionals using standard protocols, is the only way this can happen.

The government’s own management plan for feral horses states that ‘if undertaken in accordance with best practice, aerial shooting can have the lowest negative animal welfare impacts of all lethal control methods’.

This humane and effective practice is already used across Australia to manage hundreds of thousands of feral animals like horses, deer, pigs, and goats.

Trapping and rehoming of feral horses has been used in Kosciuszko National Park for well over a decade but has consistently failed to reduce the population, has delayed meaningful action and is expensive. There are too many feral horses in the Alps and not enough demand for rehoming for it to be relied upon for the reduction of the population.

Fertility control as a management tool is only effective for a small, geographically isolated, and accessible population of feral horses where the management outcome sought is to maintain the population at its current size. It is not a viable option to reduce the large and growing feral horse population in the vast and rugged terrain of Kosciuszko National Park.

Feral horses are trashing and trampling our sensitive alpine ecosystems and streams, causing the decline and extinction of native animals. The federal government’s Threatened Species Scientific Committee has stated that feral horses ‘may be the crucial factor that causes final extinction’ for 12 alpine species.

I recognise the sad reality that urgent and humane measures are necessary to urgently remove the horses or they will destroy the Snowies and the native wildlife that call the mountains home. I support a healthy national park where native species like the Corroboree Frog and Mountain Pygmy Possum can thrive.
