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. The results showed why … [Read more...] about Research shows what’s working for kiwi and kaka
How do you change public behaviour - for example, persuade cat owner's to bring their pets inside? Is education the answer? Is education enough? If people just knew more about conservation issues would they become supporters and adopt conservation values themselves? Not necessarily. The reality is … [Read more...] about Influencing conservation behaviour – the role of social psychology
Research and innovation mean that the options for helping out our native species are increasing all the time. First there were small, predator free island sanctuaries, then bigger islands and then there was Zealandia – the world’s first fully fenced urban ecosanctuary. Mainland sanctuaries … [Read more...] about Doing the sums – what are the best predator control options?
Peanut butter has long been used as a lure for rats. Possums have a fondness for the scent of cinnamon. But are they the all-time favourite foods of rats and possums? Researchers at Victoria University of Wellington used chew cards to check out what really tickles the tastebuds of two of our more … [Read more...] about Better baits and better trapping
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?
Scientific research often involves painstaking, meticulous measurement, sometimes repeated over a period of years before the work is completed – then it has to be analysed, written up equally meticulously and an academic publisher found. Not everyone has the patience or the persistence, but the … [Read more...] about Research takes the long view on native species
Many of New Zealand’s native wildlife species are not only unique, they’re downright weird. Take our singing short-tailed bats for example. Auckland University researchers Cory Toth et al have been studying their behaviour and have confirmed that they’re lek breeders. Like the kakapo parrot, male … [Read more...] about Batty behaviour intrigues scientists
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
