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)
For thousands of New Zealand’s sub-Antarctic mice, the next few weeks are the final countdown. With just a few weeks to go until mouse eradication begins on the sub-Antarctic Antipodes, this week’s Friday read looks at some of the key Antipodes-based research which has led us to this point - to the … [Read more...] about Antipodes and the impact of mice
Rats are, perhaps, the ultimate invader – with a little bit of help through the centuries from humans. Where-ever we go they go too, so that ship rats have ended up on some of the remotest of the world’s islands. Today’s research review looks at studies into rats on islands, aspects of rat biology … [Read more...] about Rats as island invaders
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
Possums are a huge problem in New Zealand – and consequently the subject of a great deal of research. Most of that research, understandably, focuses on the forests and forest remnants where they are most commonly found. But what about those urban possums, patrolling the rooftops at night, raiding … [Read more...] about Understanding possums
Stoats are a cunning opponent and serious villain in New Zealand’s battle to save our native species. They’re efficient predators, can travel long distance and are good swimmers. They’re also notoriously bait-shy. So what can recent NZ research tell us about the best ways to tackle … [Read more...] about Tackling stoats
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
