The A24 self-resetting trap has been around for a year or two now, but development of the product and testing of its capabilities continues, along with evaluations of how best to utilise the traps in ‘real world’ predator eradications. Darren Peters from DOC, along with the team from Goodnature have … [Read more...] about A24 vs Stoats – island experiment deemed a success
Conservation genetics has implications for all sorts of conservation measures whether it be choosing the source birds for a translocation to a new sanctuary to ensure sufficient genetic diversity, ‘forensic’ type investigations to identify the source of a newly arrived predator on an island (where a … [Read more...] about Conservation geneticists want to build a bridge to DOC
Breakthrough genetic technologies are likely to play a key role in achieving a predator-free future. But it’s important that we understand what the various technologies are now – as they’re being developed - not when they’re about to be implemented. We need to debate the issues and become as … [Read more...] about What’s the story with genetic pest management (GPM)?
A predator-free New Zealand is going to require landscape scale removal of possums, rats, ferrets, stoats and weasels – and possibly other species such as mice and feral cats as well. The problem – or at least one of the problems – is how do you humanely remove some species without endangering … [Read more...] about Genome-mining to find toxins that are species-selective
When scientists Patrick Garvey (University of Auckland), Alistair Glen and Roger Pech (Landcare Research, Lincoln) tested the response of 18 wild-caught stoats to the scents of bigger, dominant predators, the response of the stoats was the opposite of what they expected. The researchers used towels … [Read more...] about Predator scent may be key to developing long-life lures
Rats are a uniquely serious problem on islands such as New Zealand where there has been a rodent-free evolution of our wildlife and plantlife, but scientists around the world are also looking for better ways to control rats because of their disease-carrying and food-spoilage attributes. Black … [Read more...] about Canadian researchers come up with innovative rat-luring techniques
If you want to measure the abundance of birds in a forest you can count how many you see or record the birdsong you hear. But how do you monitor whether your predator control is increasing invertebrate diversity? As some of our larger invertebrates such as tree weta and stick insects are likely to … [Read more...] about Frass drop – finding clues from the poos
‘Raptors vs aliens’ – it sounds like the latest Hollywood blockbuster, but it’s actually the title of a paper published in the NZ Journal of Zoology at the end of last year. Written by NZ Landcare Research scientists A.S. Glen and R.P. Pech, along with two Australian authors, the research … [Read more...] about Raptors vs aliens – might it work?
‘Citizen Science’ and academia worked together in a research project near Nelson to determine the effectiveness of a predator control programme in boosting bird numbers and also to evaluate the usefulness of a bird survey method as an easy-to-use monitoring tool for volunteer conservation groups. … [Read more...] about Alternative bird survey method investigated
While PFNZ Trust focuses on 5 key introduced predator species (possums, rats, ferrets, stoats and weasels), we acknowledge that domestic pets – both cats and dogs – are also introduced predators and are potential killers of native wildlife if allowed to stray. Wandering dogs can and do kill kiwi and … [Read more...] about Tracking cats on Rakiura/Stewart Island
