Landcare Research scientists have published some fascinating research recently looking at the damage possums do the forest canopy and the surprisingly long time it takes for larger trees to recover. The first paper was published in Ecology and Evolution earlier this year and full access is freely … [Read more...] about Landcare Research takes to the tree tops in latest possum research
If we knock back ferrets and feral cats will rabbit numbers soar? It is a concern that’s frequently raised, particularly in farming areas where rabbit control is already an issue. As rabbits are the main prey of ferrets and feral cats, it seems intuitively logical that rabbits will thrive without … [Read more...] about What about the rabbits?
Science isn’t just about the big breakthroughs – although they’re great when they happen. Mostly it’s about challenging assumptions, testing alternatives and finding new and better ways to do things. Change is incremental and improvements are constantly being integrated into the way things are … [Read more...] about GPS offers aerial application alternative
Just because you’re not catching anything, doesn’t necessarily mean all predators have been eradicated. Being certain that an area is completely predator-free is a challenge in island eradications where certainty is needed before endangered species can be reintroduced. But the problem also applies … [Read more...] about Rapid eradication assessment – with online app
Trap-wary stoats got caught out by a change in predator control regime according to research just published in July this year. The research, carried out by DOC scientists and published in the New Zealand Journal of Zoology, took place in the 9800 ha Whangarei Kiwi Sanctuary.

Possums – those cute Aussie furballs are decimating New Zealand forests – so why don’t we just develop our fur industry and make money from the problem? After all, that’s why they were introduced to New Zealand in the first place. More rural employment, less possums – the bush grows back and New … [Read more...] about Possums and more possums – is a fur trade the answer?
It’s called the Trojan Female Technique and it’s involves a mutation in females that makes all their male offspring infertile. Because it is a gene, not a virus, it stays within that particular species and is spread from one generation to the next by breeding, not by disease. It has the potential … [Read more...] about Trojan Possums – are they the next step?
Fundamental to a well-managed pest control programme is detecting what predators you have and monitoring the changes in abundance as your trapping regime progresses. Leg hold traps are a traditional way to achieve this, but may not be sensitive to possum presence when possum levels are at very low … [Read more...] about Detecting predators – can you count on chew-track-cards and WaxTags?
Rest assured, New Zealand’s scientific community are beavering away to find new and better ways to combat possums. These are just a few of the research reports investigating possum control recently published in the New Zealand Journal of Ecology. Firstly a poison bait evaluation was … [Read more...] about New ways to combat possums
The detrimental effects of New Zealand’s larger mammal predators are very well documented. Everyone surely knows the devastation caused by rats, possums and stoats. So what about mice? At this time of year they can be a nuisance in your pantry and a worry to your wiring – but what are the impacts of … [Read more...] about Skinks, geckos (and mice)
