Rats and mice aren’t just our problem. They’re some of the most widespread and damaging invasive alien species on islands globally. A team of scientists lead by Karl J. Campbell from Island Conservation and including New Zealand-based scientists Al Glen and Charles Eason, have carried out an … [Read more...] about What next for rats and mice?
Kakariki, our native parakeets mostly nest in holes in trees, where the female incubates the eggs for around 3-4 weeks. That makes female kakariki, as well as the young, particularly vulnerable to predators and could potentially lead to a male bias in the adult population. Red-crowned kakariki … [Read more...] about Predators vs Parakeets
Stoats are emerging as a key threat to our alpine wildlife as scientists learn more about predator/prey relationships in this less-studied habitat. Remote alpine zones are home to unique skinks and geckos, some of which have only recently been discovered, along with insects such as alpine weta … [Read more...] about Alpine stoats caught on camera raiding rock wren nests
Before humans arrived, 78% of Aotearoa was covered in native podocarp forest. In the 700 years since we got here, 60% of that forest has gone. The good news is that at least some of our native species are managing to make do in the blocks of exotic forestry plantations that now cover approximately … [Read more...] about Falcons learn to live an ‘exotic’ life
Rats are fastidious groomers. So how does an animal that grooms frequently react to the prospect of running through viscous tracking ink? Are rats reluctant to get their feet dirty – and if so, what are the implications for tracking tunnel monitoring? Prof. Carolyn King and fellow researchers … [Read more...] about Do rats mind inky feet?
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
