ACT reserves are open to the public again after 1041 kangaroos were culled as part of a government program aimed at protecting vegetation and vulnerable species.

Now the cull has concluded, Mulanggari Grasslands, Red Hill Nature Reserve, Pinnacle Nature Reserve and Molonglo River Reserve (Kama section) have fully reopened.

They were among the six reserves across the ACT that were closed in June and part of July to allow for the annual Kangaroo Management Program.

Two other reserves will continue to have periodic closures for rabbit control.

ACT Conservator of Flora and Fauna Bren Burkevics said the ACT Government needed to balance kangaroo numbers with the wellbeing of other species and the wider environment.

“We go through extensive processes to calculate the number of kangaroos that are sustainable on each reserve,” he said.

“As we go through that process, we calculate the number of kangaroos that are estimated to be on each reserve, and then identify how many kangaroos have to be removed.”

“If we don’t manage kangaroos, they become overabundant and graze out some of these critical grasslands, which of course are home to a great many threatened species.”

The ACT will also continue to use GonaCon immunocontraceptive vaccine as a non-lethal way to control the kangaroo population. The vaccine is given to female kangaroos and leaves them infertile for about seven years.

“GonaCon will be an ongoing part of the Kangaroo Management Program, outside of culling operations,” Mr Burkevics said.

“We’re seeing some early pleasing results from the delivery of the GonaCon vaccine, which was first used last year.”

Mr Burkevics said the ACT Government hopes the vaccine will mean fewer kangaroo culls are needed in the future to manage the population.

“It’s not going to eliminate the need to cull kangaroos, but we really hope it reduces the need for and the volume of conservation culling,” he said

He said he was confident in the work of those involved in the cull, and thanked Canberrans for being patient while the reserves were closed.

“I think it’s fair to say that all of our conservation officers that have carried out this program have worked to exceed the national code of practice for the humane culling of kangaroos.

“I personally observed the operations on Red Hill and was extremely impressed by the quality, the robustness and the commitment that was delivered in terms of public safety and animal welfare,” he said.

While the kangaroo cull has finished, Mount Majura Nature Reserves and parts of Mount Ainslie will remain closed from 8 pm to 3 am on Tuesdays and Thursdays to allow for ongoing rabbit control operations.

“The management of rabbits and other invasive pests and weeds are another important part of the work we do in conservation and land management,” Mr Burkevics said.

Skeptic9999. There certainly have been some co-incidental(?) land developments post kangaroo ”culls” in some locations. You can’t really blame people for thinking the killing of kangaroos in Canberra nature reserves is related to urban and infrastructure development. If the official reasons for killing wildlife seem so spurious, then many people will try and make some sense of it. Making sense of the mass slaughter of wildlife is something a lot of people find very difficult. I’m sure you could understand that. It doesn’t matter if animals are ”abundant” or in precarious numbers, the wilful killing of kangaroos (in this instance) is reprehensible to people who despair about our governments’ cavalier attitudes to wildlife.
As for science having the final say: it is undeniable that, seen over many decades, land “management” in Australia, including supposed scientifically supported land management, has a disastrous history. This science-based land management has always been advocated by authoritative people who have claimed to know what is correct, only to be shown, subsequently, to have been grievously wrong. The outcomes have been shocklingly degraded soils and watercourses and the loss of native flora and fauna. In life and death cases for native animals in particular, it’s not just about science, it’s also about morality and ethics.

Hi Riot Act – can you please delete my previous comment as I accidentally pressed submit before I was finished. It has a number of spelling errors. The correct comment is –

Skeptic 9999 – that is not what I said.  After killing kangaroos new developments are rammed up against the nature reserves.  There is absolutely no guarantee that the land will remain as reserves.   True to form – a change in legislation will do it.  I have provided a link to the evidence of all the wrongdoing by this cruel and corrupt ACT Government – No transparency, no accountability, no oversight, “robokill” – garbage in garbage out, .  Make no mistake all the Ministers and public servants, even the retired ones, responsible for the ACT kangaroo “cull”, will be held to account for the extinction of EGKs from Canberra.

FACT CHECK-We can’t kill our way back to biodiversity. Instead compassionate conservation is gaining support within conservation science. Compassionate conservation promotes the treatment of all wildlife be done with respect, justice, and compassion. One of the guiding principles is peaceful coexistence. Whether species are common or rare, whether native or not, all wildlife have intrinsic value. It is well known that human activities harm wildlife. Compassionate conservation aims to find solutions that minimise that harm.

So instead of continuing to live in our colonial past of over-exploiting wildlife, where the language for killing is coded as “culling”, “population control”, “hunting”, “environmental damage”, the ACT Government needs to move to protecting our wildlife and restoring lost wildlife habitat for future generations.

Furthermore, how can anyone believe anything the ACT Government says when it is a matter of public record that at the ACAT 2013 hearing, Don Fletcher, one of the architects of the kangaroo killing program, made the astonishing admission that TAMS’ assertions that the cull will protect threatened species are just “PR”. At the same hearing, he also admitted his only basis for asserting that kangaroos have a negative impact on reserve ecosystems is that kangaroos eat grass. The CSIRO Plant Industries Report in 2014 confirms the expert opinion expressed at those hearings:  ie-the Government’s use of grass mass as the indicator for diversity is patently absurd.  It is the number and variety of plants and animals, not mass of vegetation that gives all species the best chance to live and thrive.

In addition, Don Fletcher admitted that the purpose of the cull was not to stop damage being done by the kangaroos but to prevent damage that might possibly done in the future if all aspects of his assumptions and modelling were correct (WHICH HE ADMITTED THEY WERE NOT).

Thanks for starting your comment with an acknowledgement that it required a Fact Check.

The anti-cull brigade sure do come out with some weird stuff to justify their support of the continued degradation of our environment and biodiversity caused by Kangaroos.

Chook58, I note you don’t dispute the finding of non-facts in your earlier replies, eg your claim that the culled areas have been developed (false). Great! Please stick with that.

Can you provide a URL or some ORIGINAL evidence from ACAT for these words you are putting in the mouth of the ACT Government, because they sound a bit much like a ‘straw man’.

And please please please provide some scientific evidence for your claim, which we have been hearing for many years, that ‘eastern grey kangaroo populations already in steep and alarming decline’. Animal activists like you have been asserting the EGKs would go extinct in culled reserves since the year dot, but so far the kangaroos have been resolute in disobeying your predictions!

Given your record with the facts, even just here in the comments on this story, Why would we not prefer to believe the ACT Government?

Your reply demonstrates it requires very little thought and no effort whatsoever to scapegoat kangaroos for the environmental damage caused by humans.

FACT CHECK: None of the culled areas has been developed Karl Herzog. It is one of the lies made up by right-to-lifers, and has been around since Defence started culling in the Belconnen Naval Transmission Station in 2007. That area inside the security fence has been claimed many times to have been developed, but it has not. (Go, look for yourself!) Only the area outside the fence has been developed. Ditto for all the other cases, eg Chook58 claims here that Googong was culled in 2004 to provide for the Googong Estate development, but the cull was in the reserve around the reservoir and the development was on the Googong and Beltana freehold properties. (Different places with similar names.) Ditto for all the reserves culled, eg Callum Brae, Jerrabomberra East, Jerrabomberra West, Mullanggari, Gungaderra, MT Painter, The Pinnacle, and Mt Majura NATURE RESERVES. They are all there still, not developed and probably never will be developed. Facts matter to some of us. And a map can be a very handy thing when claims are being made about where events took place.

Hi Don Fletcher – the EPSDD claimed there were 1748 kangaroos on Red Hill in 2022, they then apparently killed 500, this should leave 1248 kangaroos. In the recently released Conservation Management Advice Report for 2023, they are now saying there are 842 kangaroos on Red Hill. Please kindly explain where the 406 remaining kangaroos have vanished to? Given you yourself stated that kangaroos do not do mass migration so did these kangaroos just vanish into thin air?

Can you give the rest of us the URLs or references where we can see these count and cull numbers for ourselves? Is the 842 significantly different from the expected post-cull values?

After 14 years of the annual “cull”, killing kangaroos has proved nothing! Developers, with the approval of Andrew Barr and Rebecca Vassarotti, are master designing out kangaroos from the Bush Capital. As far back as 2004 Googong’s population of kangaroos was decimated to make way for the suburb of Googong, in 2007 kangaroos were slaughtered to make way for the suburb of Lawson and on it goes. In Red Hill the killing of kangaroos is to make way for 152 units around the Federal Golf Course.

It is impossible to reconcile the Government’s position for killing kangaroos with the facts.  Their alleged science was exposed as nonsense during the 2009, 2013 and 2014 ACAT hearings, and in numerous well-researched submissions made during “public consultations” on the 2010 and 2017 Kangaroo Management Plans.  The CSIRO Plant Industries Report in 2014 confirms the expert opinion expressed at those hearings.

Many Canberrans are unaware the ACT government has its own cousin of Robodebt, which it is just as wildly inaccurate and even more cruel. ACT’s “Robokill” is a legislated and automated calculator that routinely estimates four times more kangaroo than are actually present on Canberra reserves. Consequently, the kill calculator requires kangaroos are killed much faster than they can possibly replace themselves. With eastern grey kangaroo populations already in steep and alarming decline, reducing their birth rate is no better, from an ecological point of view, than increasing their death rate. Both changes the kangaroo’s gene pool diversity and population dynamics forever.

Instead of wasting hundreds of thousands of public money every year killing kangaroos, Barr and Vassarotti are deliberately ignoring the humane and viable alternative.  That is to build a series of wildlife corridors to connect Canberra’s Nature Reserve system and allow wildlife and people to move around the city safely.

Nah Chooky58. Here are a few facts to counter some of your propaganda:
1) Canberra is exceptionally well provided with wildlife corridors that have been used by small pioneering groups of kangaroos to reach every suburb, and in some cases to establish new kangaroo populations in areas that had no kangaroos previously, eg Weston Park. However the nature of EGKs is that they are faithful to a home range and as adults, highly reluctant to move from it (though juveniles do disperse), so there is no mass movement of hundreds of EGKS between reserves.
2) The Government kangaroo counts have been checked by experts and are correct. Uneducated protestors repeatedly challenge them (same with all wildlife controversies, eg the horses in Kosciuszko) but have yet to produce any credible skerrick of evidence to challenge them.
3) You LOST all your court cases. What was ‘exposed as nonsense’ was YOUR evidence, not your opponent’s evidence. For example the Animal Lib kangaroo counts were less than the numbers subsequently shot in the same areas, which was a small proportion of the total.
4) On the Environment ACT web page are references to 8 papers showing impacts of kangaroos on other native species, including threatened species. No one would claim that kangaroos impact everything. They are highly beneficial to some things and have neutral effects on some others, as some research shows, eg the report you mention, but that report does not mean that the other undesirable effects are not happening, including the ones recorded in those papers.

Skeptic9999. Regarding the government kangaroo counts which you say have been checked by experts and are correct. In 2022, the kangaroo population on Mt Ainslie/Mt Majura was 2,770. Where are these kangaroos? People have been searching for them and have been unable to find anything close to that number. Please advise. As you’ve stated in Point 1 they are loyal to their home range so I am sure you can advise the approximate locations where they can be found.

Motojohhno,
It’s hard to find something you’re actively trying not to see with your eyes closed.

Hi Motojohnno61, I have followed other wildlife controversies as well as the Eastern Grey Kangaroos in Canberra Nature Park and your comment is a very polite (thank you!) version of the commonest comment I see, which is expressing doubt about the official numbers of animals. The interesting thing, is that the most widely used counting method (Line Transect Distance Sampling on foot, or from a ‘platform’ such as a helicopter or a ship) is known to almost always underestimate slightly. But non-ecologists frequently express the view that the counts must be overestimating wildly, based on their casual inspection of the area. So there is a huge gap between what these non-ecologists see

There is a huge gap between what these non-ecologists see, and what the science reveals. I’d love to see how I can explain better than that.

Presumably it is also hard for untrained people to accept other numbers too, like the number of stars in the visible universe, the number of cells in your body, the number of atoms in a gram of a substance etc. But they get more impassioned about the number of horses, deer, kangaroos, etc. Worse with fish. Commercial fishing people really really cant believe the scientists about numbers in some of those cases.

I know it’s not nice but I understand the need for a cull however, I’m not convinced the recent cull is necessary. If anything I suspect it’s got more to do with the real estate expansion then the environment. I’ve noticed the areas they’re culling are where suburbs are being built.

No-one, NO-ONE has committed so much to finding practical ways to do kangaroo fertility control as the ACT Government. With various research partners it has been participating in this effort since 1997, meanwhile keeping an eye on other researchers trialling different agents at Melbourne Uni, Macquarie Uni and Sydney Uni. Now Gonacon, first researched and imported by CSIRO, has proved to be by far the best agent so far. The first female Eastern Grey Kangaroos were treated with Gonacon in 2008, in Canberra, in joint research involving CSIRO, Newcastle Uni and EPSDD. Those females treated with one Gonacon injection as sub-adults lived long infertile lives and grew extra well, having been freed from the cost of reproduction. (Meanwhile another two products trialled at the same time both failed.)

The current population-level deployment in unfenced reserves is a big challenge and will be an international breakthrough if it works well. I can hardly wait for the next few years to hear how it goes.
