Deep Creek concerns: Post-fire window closing as feral deer trample iconic national park in recovery

The Invasive Species Council is encouraging the state government to make the most of the opportunity to remove feral deer from Deep Creek National Park, as part of its recovery plan from the bushfire that burnt thousands of hectares earlier this year. 

Around 40% of the park – more than 4,500 hectares – was burnt in February 2026, leaving fragile landscapes exposed and highly vulnerable to damage from invasive species.

‘The months after a bushfire are among the best times to control feral animals, which congregate in the few remaining areas where feed is available. The open landscape makes it easy to locate feral animals and to use humane control methods such as aerial control to quickly reduce their numbers,’ Invasive Species Council Senior Advocate James Johnston said.

‘We are deeply concerned that we are seeing evidence already of feral deer within the bushfire recovery areas doing irreparable damage to this fragile environment. 

‘Currently, the park is closed 1 week per year for Pest Control, which is coming up later this month. 

‘Populations of feral deer have been stubborn to knock down historically here. Evidence shows that you have an 18-month window to make the most of bushfire recovery to knock down invasive populations. 

‘To capitalise on this opportunity, we encourage the state government to double its efforts and deploy additional resources while this window is still open. 

‘This could involve either deploying an extra helicopter or additional ground personnel in May. Alternatively, dedicating an additional week later in the year in the spring.

‘We have an opportunity to knock populations down more than in previous years, and the government would be remiss to let it pass.

‘We have been here before as a state – with the recovery after the Kangaroo Island fires, the government took the opportunity to remove remaining feral species and now we are heading towards a feral-free island.

‘Let’s replicate this in one of our most iconic national parks, Deep Creek, which has critical habitat to some of this state’s most endangered species – including the endangered western firetail.

‘We are encouraging the South Australian government to deploy extra resources to this program and make the most of this opportunity.’

Your gift is a lifeline for nature.

Our protected areas are being trashed, trampled, choked and polluted by an onslaught of invaders. Invasive species are already the overwhelming driver of our animal extinction rate, and are expected to cause 75 of the next 100 extinctions.

But you can help to turn this around and create a wildlife revival in Australia. 

From numbats to night parrots, a tax-deductible donation today can help defend our wildlife against the threat of invasive weeds, predators, and diseases.

As the only national advocacy environment group dedicated to stopping this mega threat, your gift will make a big difference.

A silent crisis is unfolding across Australia. Every year, billions of native animals are hunted and killed by cats and foxes. Fire ants continue to spread and threaten human health. And the deadly strain of bird flu looms on the horizon. Your donation today will be used to put the invasive species threat in the media, make invasive species a government priority, ensure governments take rapid action to protect nature and our remarkable native wildlife from invasives-led extinction, death and destruction.

    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.
