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

It’s a delicate balance and often a controversial subject where strong … [Read more...] about Bait residue issues
The battle for the bush (and swamp, riverbed and shore) is being fought not just on the ground in New Zealand, but also in research labs and on computer screens around the country. New ideas are being brainstormed and innovations in predator control are being computer-modelled and tested in the … [Read more...] about Mice, rats and multi-capture traps
