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

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?
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
Environmental monitoring is more than just a modern conservation buzzword. It’s an essential tool in determining whether all those volunteer hours put in by your community group is achieving positive, measurable change. Positive change is not just dead rats, dead possums and a truckload of weeds … [Read more...] about Monitoring matters
Braided river systems are rare throughout the world, but we have some superb examples in New Zealand, particularly in the Canterbury and Southland regions. New Zealand’s braided riverbeds are breeding grounds for some very special wildlife including the wrybill – the only bird in the world with a … [Read more...] about Braided rivers and predator monitoring
No-one wants to see the birds and other wildlife we’re trying to protect, killed or in any way harmed by the very methods we use to protect them from predators, either by consuming bait or being accidentally caught in traps. It’s a delicate balance and often a controversial subject where strong … [Read more...] about Bait residue issues
