Goannas and Baits

[Die Judicii]

Does anyone on here know if poison baits will kill goannas or not ?

I know a landowner that has been putting out baits around his hen houses for just on 3 months now.
He tells me that every morning the baits are all gone,,,,, but he's never yet found a dead carcass anywhere.

With these particular baits, foxes never get any further than 100 meters after consumption before dying.
We've sort of ruled out crows cos of past experiences, there are no dead foxes or cats, and with the sheer number of baits that are taken we've also ruled out feral dogs.
The only thing I can think of that may survive eating these baits is a LARGE goanna.
Anybody got any useful info as to what might be taking the baits ?

I'm going to put out 4 or 5 trail cameras in the next few days to see if I can catch the culprit on film.

Not sure what poison or compound you mate is putting out, DJ, you don't say, but recommended 1080 doses used for introduced species are safe for native animals.

Mate, from the literature I've got - fact sheets from credible test labs and the feral animal coordinator control bloke from the Southern Downs Council, the LD or lethal dose for cats, dogs, foxes, pigs whatever, from 1080 is not lethal. Not even close.

Any recommended LD in a 1080 bait is strictly controlled and farmers just can't spread 1080 around without supervision, thank goodness.
However our native Aussie animals have developed a natural resistance to 1080 because it's naturally occurring here. In the south-west of WA – where more fluoroacetate-bearing plants naturally occur – have an even higher natural tolerance to 1080.
Pea bush in WA, Gidgee in Qld and the NT contain sodium fluoroacetate poison so our animals have developed a natural resistance to it, even when concentrated - up to a point. This point is not even close to being reached deliberately in any 1080 baits in Aus, and it's not cumulative.

Goannas on my place routinely try and steal any meat baits laced with 1080, and are still there to steal the next round months later.
There is so much cr@p on social media, unfortunately repeated by parrots, saying 1080 kills everything else along with the target animal. It comes from not just greenies, but shooters as well.

A copy/paste from some data I have:
"The amount of 1080 injected into each wild dog and fox bait is deadly to those species but safe for native predators, including birds of prey (e.g. wedge-tailed eagles), reptiles (e.g. goannas) and the iconic spotted-tailed quoll. This is because they are much more tolerant to the poison than the wild dogs, foxes or feral cats the baits are designed to target.

Spotted-tailed quolls, the largest marsupial predator on the Australian mainland, thrive in areas of New South Wales that have aerial baited wild dogs and foxes for decades. Baiting reduces the risk of predation and competition for resources.

Intensive research undertaken within Kosciuszko National Park and the New England tablelands between 2002 and 2005 showed that spotted-tailed quoll populations were unaffected after individuals ate meat baits containing 1080 (Claridge et al., 2006, 2007, Kortner 2007).

The proof came from adding a special dye to the 1080 meat baits, one that can later be detected in their hair and whiskers of animals that have consumed baits. The whiskers from resident animals trapped after the baiting showed that many had eaten baits with some individuals consuming up to five. These same quolls were recaptured in following years and showed no ill effects from eating baits containing 1080. As a result, in 2006, NSW National Parks and Wildlife Service overturned their ban on 1080 aerial baiting for wild dogs based on this research.

Rather than being harmful, 1080 is Australia’s natural toxin. It’s target-specific, biodegradable, and an essential tool in the fight to protect Australia’s unique wildlife and ecosystems from the impacts of introduced, feral animals."

that's very enlightening wapati . thanks for posting

[Blr243]

Ditto. I learned from that info

[Die Judicii]

Yep, thanks for digging up all that, and posting it.

I didn't know 1080 was less lethan for natives, thank you.

You could always try setting up a trail camera to see what's in the area

As I said when I started this thread,, I was gonna put up a camera or two.
Did that, and checked em today.
From the three cameras I had spare and set up, I got good results.

Two foxes, one fat and healthy, and one very lean one.
And as a bonus, I also had some pics and Vids of a dog.

So I told old mate to dispose of his cache of the poison he was using, as it was obviously old, out of date, and ineffective.

thats some interesting info about the natives ,thanks I would have thought it didn't matter what ate them ,but there you go ,thanks
