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
Birds can spend a significant portion of their lives at roosting sites – up to two thirds of their time – so it makes sense that suitable sites are important to them. With translocation being a key strategy in rare species management, it would be good to know what features our bird species value in … [Read more...] about What makes a great kiwi burrow?
Weka are largish, robust-looking and with a keen curiosity that suggests they’re no birdbrains. They’re also opportunist pilferers if there’s chook food around or even leftovers in the dog’s bowl. They’re tough enough that in some cases they’ve had to be eradicated from offshore islands because of … [Read more...] about Weka are tough – but are they tough enough?
Cats, cat management and the impact of cats on conservation – it seems that everyone in New Zealand has an opinion and a significant proportion of us own at least one companion cat – but what is actually known about the multiple roles of urban cats in New Zealand? It is becoming an increasingly … [Read more...] about City cats – what don’t we know and how can we find out?
It has been estimated that between 25,000 and 45,000 people belong to community-based environmental groups in New Zealand. That’s a lot of volunteer work and, as the estimate was made in 2011, numbers since then are likely to have grown. There’s also a pretty wide range of uncertainty in those … [Read more...] about Survey investigates huge volunteer contribution
When there’s a mouse in your pantry you notice – but in the wider environment they’re common and inconspicuous. It’s difficult to know what impact mice have in a forest or wetland environment because mice are overshadowed by – and food for – their bigger predator rivals, including rats, stoats and … [Read more...] about Mice – should we be worried?
Blue ducks (whio) live in both the North and South Island – they’re isolated by distance, but how isolated are they genetically? Physically there are visual differences – the South Island whio is larger, for example. But just how deep do those differences go? Genetic difference matters when … [Read more...] about Blue ducks – how different is ‘different’?
Ship rats are known to be good and climbing trees – but what are they like at climbing mountains? If our climate gets warmer, might rats go to new heights in the search for new territory and food? Scientists Jennifer Christie and Graeme Elliott from DOC’s Christchurch office, along with Peter … [Read more...] about Rats, elevation and implications of climate change
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)?
