Several parks and reserves across the ACT will be temporarily closed for an animal control program targeting pest species.

In the Thermal Assisted Aerial Control program, vertebrate pest species are culled from key conservation areas, water catchments and semi-urban areas in the ACT.

It means parts of Namadgi National Park, Tidbinbilla Nature Reserve, the Murrumbidgee River Corridor and Molonglo River Reserve, along with some adjacent land, will be closed in May.

The closures will be staggered over several weeks.

ACT Parks and Conservation Service’s executive branch manager Michaela Watts said the closures are put in place for the public’s safety while the ACT Government carries out the annual program.

“Vertebrate pest species such as pigs and deer can threaten the native ecosystems and habitats of threatened species in the ACT’s parks and reserves,” she said.

“This program has been running in the ACT since 2021 and focuses on reducing the impact these vertebrate pest species have on our natural environment. Last year we expanded to include areas of rural properties adjacent to our conservation areas.

“Feral pigs and deer are established in many areas of the ACT, and ongoing control is required to reduce the impact of these animals.”

Ms Watts said the program was the best option to manage the animals’ populations.

“Aerial shooting is the most effective and humane method of control available for large feral animals,” she said.

“Thermal imaging cameras are used to detect and target animals, increasing the effectiveness and animal welfare outcomes.

“Extensive safety precautions will be in place, including buffer zones, signage and sweeps prior to all operations. The community should also be aware that aircraft may be operating within the closed areas.”

The specific closure dates are below:

  • Bullen Range Nature Reserve: 8 May – 18 May
  • Gigerline Nature Reserve: 8 May – 18 May
  • Rob Roy Nature Reserve (South): 8 May – 18 May
  • Stony Creek Nature Reserve 8 May – 16 May
  • Molonglo River Reserve: 12 May – 16 May
  • Tidbinbilla Nature Reserve: 15 May – 16 May
  • Namadgi National Park (West): 16 May – 27 May
  • Namadgi National Park (Naas – East): 19 May – 28 May
  • Namadgi National Park (North): 19 May – 28 May
  • Lower Cotter Catchment: 19 May – 28 May
  • Googong Foreshore: 26 May – 29 May.

Also, the Australian Alps walking track will be closed from the Mt Tennent summit to the NSW border in Murrays Gap from 16 to 27 May.

The Mt Tennent Summit Track from the Namadgi Visitor Centre will remain open throughout the control program.

The Murrumbidgee Discovery trail will be closed from Pine Island to Casuarina Sands, which includes a section of the Centenary trail between Kambah Pool and Pine Island, during this period.

In 2024, the program resulted in the killing of 284 feral pigs, 357 feral deer, 119 feral goats, and seven feral horses from populations in Namadgi National Park, the Murrumbidgee River Corridor, Molonglo River Reserve, and Googong.

The ACT Government’s approach to invasive species management prioritises animal welfare. All control activities are undertaken in accordance with best practice and humane control of feral animals.

What damage are these animals causing ScribbyGum? Be specific otherwise your comments simply reflect the same ignorant, unscientific message from this wilfully dishonest ACT government

chook58, There is no measurable damage from deer, pigs, goats or horses; well I hope not. Proper management PREVENTS damage. Likewise, good management would be removing few animals per year because pest density is being successfully kept low.

There are shelves of scientific books about the damage done by vertebrate pests, even including books about damage specifically by pigs, goats and horses. And there are countless scientific papers in peer reviewed journals about all of the target species. Here is one example: Ramsey et al (2023). ‘The application of catch–effort models to estimate the efficacy of aerial shooting operations on sambar deer (Cervus unicolor)’. Wildlife Research 50, 688-700. https://doi-org.ezproxy.canberra.edu.au/10.1071/WR22123
If your knowledge of the field is such that you have seen none of that, you are best advised to trust what the scientists say, based on their training, qualifications and career experience.

There are even books based on study of feral pigs in the ACT, such as ‘Applied Population and Community Ecology’ and ‘Wildlife Damage Control’, both by Emeritus Professor Jim Hone at the Uni of Canberra, (available in bookshops).

pestsmart.org.au provides vast resources once you know what to look for but items are not easily grouped by search topics, e.g. ‘impact of feral pigs’. Many state governments have fact sheets and the like on their web pages, which give a better introduction, eg https://www.dpi.nsw.gov.au/biosecurity/vertebrate-pests/managing-vertebrate-pestsm
Included in the above is this brief guide which has some references to further information https://www.dpi.nsw.gov.au/biosecurity/vertebrate-pests/managing-vertebrate-pests

chook58, as children, we think of animals as humans writ small. Children might judge a fox for killing a bandicoot or a rabbit. A more mature view appreciates that justice is inapplicable; that in reality the bandicoot is not innocent and the fox guilty. Animals can be neither guilty nor innocent.

That animals are never guilty does not mean they do no harm. Scientists concur that introduced species are a major cause of biodiversity loss. There is often no non-lethal alternative.

You do not enjoy being informed of the killing. But that does not mean it is unethical. I hope that governments will forever disregard both the views of children on this topic and complaints such as yours, that animals should not be killed because they are innocent scapegoats, through no fault of their own.

Fox killing rabbit = good.
Fox killing bandicoot = bad

All this “brainless” ACT Government is good at is kill, kill, kill when there are plenty of non-lethal measures. Any thinking person knows that the Australian landscape has been radically changed since European settlement. We can’t kill our way to biodiversity. Introduced animals, through no fault of their own, have been abandoned to fend for themselves. They are being used as scapegoats for the damage caused by people.

The control of these large, ecosystem-altering foreign species is evidently being continued annually in the conservation reserves. Well done ACT Government, and all who are responsible.

In reply to this annual announcement, hunters have previously complained that the meat should not be ‘wasted’, and that hunters could do the job cheaper. Ecology says both complaints are wrong.

First, the nutrients that grew the meat came out of the environment and need to go back. If the large herbivores are continually harvested for meat, either the soils will become even less fertile than they are by nature, or we would have to fertilise national parks, like farms. So please leave carcasses to rot, ACT Government, as is being done in NSW with horses, deer, pigs and goats.

Second, hunters customarily go where the deer and other target animals are abundant. Maximum yield of deer carcasses is obtained when the population is reduced by about 10%. However for the impact of a species to be reduced, its abundance must be kept low, typically around 90% below maximum. Voluntary hunting does not work well for that circumstance.

As experts have repeatedly advised (ecologists and animal welfare vets with ballistic expertise), heli-shooting is the method of choice for reducing most populations of unwanted large animals because it is more efficient and more humane than other shooting alternatives. And heli-shooting is greatly improved by thermal-assist. So until research comes up with humane, target specific and efficient poisoning options for deer and these other pest species, thermal assisted heli-shooting is the way to protect our parks.

I hope those feral pests don’t have internet access. 😐

Why? I don’t get the joke, can you explain it?

Because they’ll know when to hide

Because now they know when to hide.

Yeah, still don’t get the joke due. Seems lame.

Actually I take it back, I’m wrong, that’s on me.

You’re doing a joke about animals hiding, when I misread it as having a go at people concerned with the treatment of animals. My bad.

Where are all the kanagroo lovers…. I’m guessing pigs, goats, deer and horses dont count when it comes to saving animals, but you need to save Skippy
