Yes, Brodifacoum was used and aerially applied for the Brook Sanctuary.
As have most other of the offshore predator free islands.

It certainly was aerial dropped there. Not only did my wife work for them but I also knew the managers of the campground right next to the sanctuary at the time

That’s obtuse. The 5 percent death rate is with repellent. The higher by kill rates are without repellent at max sow rate.

Only needs to be 'controlled' sufficiently to allow native populations to flourish though, remembering that a level of browse is desirable to ensure regen and spread of certain species' seeds. 'Uncontrolled' populations of deer (or to put it the other way deer populations controlled by the available levels of food) are insanely damaging to bush and prevent a lot of flora replacement from growing through. Possum, rat, cat, and mustelid have the potential to be more damaging on native bird as especially cats and mustelids don't have other options for food when birds and eggs run out...

Conversely 'uncontrolled control' leads to issues with bykill, species damage and non-tracked effects (invertebrates, amphibians, bats, aquatic) so there has to be an acceptable level of where we say that's it we've cracked it.

Bit like the numbers of sheep quoted in NZ - a very well educated, scientifically generated wild arsed guess!

Bingo, gold star right there.

well allow me to wade on in here....
when thousands of possums were being shot,poisoned or whacked on the noggin with a 16oz claw hammer,the population was being lowered daily..... they would however have still been rooting like rabbits in the rooting season and repopulating country,HOWEVER.... there was less possum poontang to be doing the funky chicken than there would have been had the said shooting poisoning and noggin whacking been happening..so LOGIC WOULD SUGGEST the population was lowering by degrees


and I do not believe you need a degree to conclude that all the shooting,poisoning and noggin whacking was helping lower the poulation

and again I do not believe you need a degree to conclude that doing more shooting,poisoning and noggin whacking would still help to lower the population again....

The trust trying to eradicate Grey squirrels in the UK are making huge inroads with a bait that sterilises them from what I have read somewhere recently (wish I could remember where) and I have long advocated that is what we should be pushing for rather than poison.

This is good. It bypasses the issue with GMO to ensure eg a possum/rat only produces male offspring. The issue there is if a rat gets on a ship it could be all over for the country they get to.

Always identify your target beyond all doubt because you never miss and I will be missed
