A 22-year study in Tongariro Forest has followed 142 radio-tagged North Island brown kiwi through 4 landscape-scale aerial 1080 operations, covering an area of 20,000 hectares. Not only did all 142 kiwi survive the 1080 drops, but the long-term study reveals a swag of other interesting information … [Read more...] about Long-range study follows kiwi for 22 years
Peanut butter is the standard rat attractant – and apparently, they’re pretty keen on chocolate and Nutella too. But researchers at Victoria University of Wellington’s ‘Centre for Biodiversity and Restoration Ecology’ have come up with some chemical compounds that wild rats seem to rate even better … [Read more...] about New clues in the search for synthetic lures
Recently there have been several research projects looking at predators in the alpine environments of the South Island. It’s a completely different ecosystem to the much-studied lowland forest systems and there’s still a lot to be learnt about the key predator threats to our alpine species and how … [Read more...] about Latest research from Otago University and DOC investigates rock wren and 1080
To achieve a predator free New Zealand by 2050 – or by any date – the majority of New Zealand will need to back that goal. Young people in particular need to want it to happen and be engaged in making it happen. After all, it’s their future, 30 years from now, that we’re talking about. Lauren … [Read more...] about PF2050 – do young people support the goal?
Rats are bad news for nesting birds – but quantifying exactly how rat density relates to nesting success of our smallest and rarest birds is difficult for a number of reasons. They’re rare – so there’s not a lot of them to study; they are likely to live in remote locations making observation … [Read more...] about Nesting fantails balance predators and weather risks
Back in 2017, PFNZ Trust talked to Otago Zoology student Jamie McAulay about his Masters research on the diet of stoats. Well the Masters is done and dusted and Jamie’s thesis is now available online through the University’s ‘OUR Archive’ site. So what has Jamie found out? Jamie McAulay The … [Read more...] about Jamie’s thesis reveals diet preferences of alpine stoats
Monitoring is an essential part of measuring the success of a predator control programme, but monitoring methods used in forests may not be directly applicable to wetlands. Tracking tunnels may not work, for example, where water levels fluctuate significantly. It was an issue that faced … [Read more...] about Monitoring methods trialled in Whangamarino wetland
Insects get eaten too. Scientists have reported that invertebrates have been found in 10-30% of cat guts and scats in the Mackenzie Basin, suggesting high country invertebrates, including some rare endemic grasshoppers, could be vulnerable to introduced mammal predators. Christchurch-based … [Read more...] about Insects get eaten too – so does predator control help grasshoppers?
New Zealand researchers have been taking a closer look at the family histories of Man’s long-time travelling companion – the rat. Genealogy meets gene analysis in this study, carried out by Auckland University researchers James Russell, Judith Robins and Rachel Fewster and published this month in … [Read more...] about Rat genetics tracks invasion back through time
Many of NZ's introduced mammal predators – including house mice – are good at climbing trees. To understand the impact they have on tree-nesting birds and other tree-living wildlife, we need to learn more about how predators use vegetation compared with the ground. Mice aren’t commonly found in … [Read more...] about Tree-climbing habits of predators studied
