What a difference 20 years makes! The lizards of Kāpiti Island have now had 20 years of living rat-free and researchers Jennifer Gollin, Nic Gorman and Doug Armstrong have been checking out the little reptiles to see how much better they’re doing. The report on the results of their island survey in … [Read more...] about Lizards counted on predator free Kāpiti Island
Translocation is an important tool for conservation management – but it comes with risks. The capture and transfer process can be highly stressful to wildlife. Some individuals can and have died. Finding ways to reduce translocation stress can save lives. And the lives that are saved are often … [Read more...] about Less stress = translocation success for tiny rifleman
When you remove predators from islands and restore forest habitat, the expectation is that native forest birds will flourish and that the new ‘improved’ conditions may favour native birds over introduced species. But is that what happens Researchers John Ralph, Carol Ralph and Linda Long looked … [Read more...] about Tūī numbers treble in predator control study
Sanctuary fences keep predators out – but they’ve also become a popular ‘highway’ for ship rats travelling around the sanctuary exterior. Rats have discovered that the rolled steel hood (designed to stop mammals climbing over the fence), also makes a great way to get around, safely out of reach of … [Read more...] about What’s happening up in the hood?
Ecosanctuaries are currently our modern-day ‘Noah’s Ark’. In New Zealand they range from small islands in the middle of lakes and unfenced mainland ecosanctuaries to isolated marine islands, fenced off peninsulas and the ‘mainland islands’ of ring-fenced sanctuaries like Maungatautari, Orokonui and … [Read more...] about Ecosanctuaries in the spotlight
Now that an increasing number of our wildlife-rich - but uninhabited by humans - offshore islands are becoming predator free, the conservation spotlight is turning to some of New Zealand’s inhabited islands. But predator eradication becomes more complicated when people are living onsite. Its not … [Read more...] about Hauraki Gulf islanders surveyed on pest control attitudes
Maungatautari Ecosanctuary is overflowing with tūī. They’re spilling over the predator proof fence into the surrounding community, according to an article just published in Notornis – the research journal of BirdsNZ. It’s great news for those who live near the sanctuary – especially those whose … [Read more...] about Tūī spill out from Maungatautari
The ruru (morepork) is a predator – but it’s certainly not on the ‘predator-free’ hit list. Those slots are just for introduced mammal predators which haven’t co-evolved with our vulnerable native species. Ruru do prey on other native wildlife however, including endangered species, as a recent study … [Read more...] about Video camera study reveals rare birds in ruru diet
Approximately one-third of New Zealand’s islands are now free of all invasive mammals. Could Auckland Island be next? Predator control and eradication operations are often carried out in winter – when predators are hungry and uptake of bait likely to be greater. But when it comes to … [Read more...] about Would summer eradication of rodents work for Auckland Island?
