Stopping the “next rabbit”: Australia needs a National Feral Deer Action Plan

The feral deer population has exploded so much in recent years that people have referred to them as the next rabbit plague. Australia now has millions of feral deer and, without action, scientists predict they could soon inhabit nearly every ecosystem across every part of the continent.

The feral deer population has exploded so much in recent years that people have referred to them as the next rabbit plague. Australia now has millions of feral deer and, without action, scientists predict they could soon inhabit nearly every ecosystem across every part of the continent.

The good news is a draft National Feral Deer Action Plan has been developed and is open for consultation. Make a submission before the deadline at 5pm on 20 March 2023 or read on to learn more about why a plan is needed and how a national approach can be a game changer.

The rise and rise of feral deer

The spread of feral deer through Australian landscapes has been explosive. They have doubled their range since 2002 when they numbered about 200,000. Today, their numbers are estimated to be between 1-2 million, but in the absence of a comprehensive survey we don’t precisely know.

The combined potential range of the six species of feral deer currency spreading through Australia. The Climatch algorithm used to generate this map predicts which habitat and climate will be suitable to one or more species of feral deer (dark red indicating most suitable, dark green indicating least suitable). Map from the National Feral Deer Action Plan.

For many communities, deer have become an inescapable pest. You can learn more about their impacts on our bushland, environment and community by reading our background briefing on feral deer.

Uncontrolled, feral deer populations can grow by 34 to 50% every year. So far, they have been concentrated in the eastern and southern parts of Australia.

In Victoria, feral deer inhabit nearly 40% of the state. In New South Wales, they cover about 22% and are expanding their range by about 1 million hectares every year – that’s roughly the size of four ACTs!

Tasmania’s feral deer population is reported to have surpassed 100,000. Estimates suggest that tally will soar to 1 million and cover half the island state by 2050 if the Tasmanian government fails to respond to the scale of the problem.

Time for urgent action

For too long, some state governments have relied on recreational deer hunting to control feral deer numbers. While there can be a role for recreational hunters in management, exploding feral deer numbers mean we must invest in coordinated, science-based, systematic efforts to deal with the problem effectively and without delay. We can’t lay the responsibility of widespread feral deer control on recreational hunters alone, and governments must back intensive and targeted professional operations to lead feral deer control programs.

We also need a wake up call for the Victorian and Tasmanian governments. Both states still legally protect feral deer as a game animal for hunters, rather than declare them as a pest like every other state. This reflects an outdated colonial attitude to feral deer, but has serious implications for landholders in those states who have to wade through excessive bureaucratic permitting processes and pay shooters out of their own pocket to control feral deer on their properties.

We need change. All of our federal, state and territory governments must come together to revoke these legal protections of feral deer and work together to stop their continued spread. The Invasive Species Council is working with local communities and advocating with governments to help bring about this change.

The Plan

The good news for Australian bushland, farmers and the community is that a draft National Feral Deer Action Plan has been developed by a working group that included representatives from state and federal governments, farmers, shooters and the Invasive Species Council. This is the first time we have ever had a nationally coordinated response to dealing with this serious invasive species.

Implementing this national plan is our best shot at avoiding wall to wall deer across the continent.

The Plan sets out what is needed to stop the westward spread of deer and protect our precious places and wildlife in areas where deer are already established.

It seeks to create a containment buffer zone that stretches from western Victoria, through the central west of NSW, to Rockhampton in Queensland. The aim is for surveillance and removal efforts to eradicate feral deer populations to the west of the containment zone and hold back the tide of feral deer spreading from the east.

This containment zone is welcomed by the Invasive Species Council, although it could be more ambitious, and better aligned to plans already adopted by the South Australian and Tasmanian governments.

The three zones outlined in the draft National Feral Deer Action Plan.

There will also be a focus on reducing feral deer populations around sensitive ecosystems, including those in the Australian Alps and in World Heritage-listed areas like the Tasmanian Wilderness and the Blue Mountains.

While we wish specific sections were more ambitious, the Invasive Species Council fully supports the thrust of the Plan. Now is the time for unity and action to stop feral deer from becoming Australia’s next rabbit plague.

We must ensure that the plan is adopted and properly funded by the federal government and all state and territory governments early next year. This is where you come in.

Without significant resources from the federal government and a commitment to action from state governments, the plan is just a plan. You can register your support for the draft plan during the public consultation period that is open until 5pm, 20 March 2023.

To make it as simple as possible, we have set up a form you can complete that instantly sends a submission to the national deer management coordinator, with the option to add your own message detailing your personal concerns or experience with feral deer.

This plan is our chance to stop feral deer from being added to the list of Australia’s most devastating invasive species.

If we fail to check the proliferation of feral deer now, Australia will be overrun. Our World Heritage and National Heritage areas will lose understories, lose trees, lose waterways and lose out-competed native herbivores. Suburban households will see parks and gardens ruined. Farmers will lose hundreds of millions in damage to crops and lost pasture while having to spend more to shoulder growing management costs. And more motorists may lose their lives.

Australia needs the National Feral Deer Action Plan, and the plan needs your support. Send your feedback today.

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.

Do you need help?

    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.
