Small, slow-moving in cold weather and with limited defenses other than camouflage and hiding, our skinks and geckos are vulnerable to predators – but efforts to relocate some of them to sanctuaries haven’t always been successful. Researchers have been refining their methods, however, and a recent … [Read more...] about New home for barking geckos in successful penned release

Multiple methods demonstrate wetland restoration benefits
Once we called them swamps and thought of these places – if we thought of them at all – as potential farmland and subdivisions, muddy, boggy and waiting to be drained. Nowadays they’re ‘wetlands’ and its not just the labelling that’s changed. Our attitudes are slowly changing too. Wetlands are … [Read more...] about Multiple methods demonstrate wetland restoration benefits
What’s outside the fence matters too
Fenced sanctuaries don’t come cheap – but they do offer a way to create areas of rich, predator free habitat for vulnerable species. But what about the habitat outside the fence? Most research to date has looked at ‘inside the fence’ habitat and bird populations, but good habitat beyond the … [Read more...] about What’s outside the fence matters too
Goat Island rat abundance measured in multiple ways
Markus Gronwald and James Russell from the University of Auckland recently measured rat relative abundance on Goat Island, 70km north of Auckland. Both camera traps and digital strike counters for Goodnature A24 self-resetting traps were used and the results compared. A total of 7155 videos, more … [Read more...] about Goat Island rat abundance measured in multiple ways
Volunteers monitor kiwi dispersal for 8 years
Between 2010 and 2016, the community group Friends of Flora Inc., in partnership with the Department of Conservation, translocated 44 roroa (great spotted kiwi, Apteryx haastii) to the Flora Stream area in Kahurangi National Park. But that was just the beginning of the project. Each kiwi was fitted … [Read more...] about Volunteers monitor kiwi dispersal for 8 years
Plastic nest material is potential threat to gannets
Ocean plastic is a worldwide problem – and its impacting wildlife here in New Zealand too. A recent study checked out how much plastic is turning up in gannet nests at a Hauraki Gulf gannetry and found an alarming 86% of nests had at least some plastic included in their construction! Australasian … [Read more...] about Plastic nest material is potential threat to gannets
Are weka ‘good predators’?
Weka can be engaging and entertaining, but their opportunistic appetite for other birds’ eggs and chicks can cop them some controversy. They’re not always welcome at ecosanctuaries, for example, even though their own numbers are threatened. Parent weka feeding chick, Brook Sanctuary, Nelson. … [Read more...] about Are weka ‘good predators’?
Sugar intake of kākā measured at ecosanctuary feeders
Otago University zoologists Anna Aichele, Philip Seddon and Yolanda van Heezik have been measuring the sugar intake of kākā at Orokonui Eco-sanctuary just north of Dunedin where sugar water feeders regularly entice birds down from the trees to the delight of visitors. It’s a great way to bring the … [Read more...] about Sugar intake of kākā measured at ecosanctuary feeders
River tested as reinvasion obstacle to possums
Reinvasion by predators, of previously cleared areas, is one of the many challenges of becoming predator free. We can’t fence huge tracts of wilderness – but we can potentially make use of natural barriers. Possums, for example, may be reluctant to cross rivers. Possums may be reluctant to cross … [Read more...] about River tested as reinvasion obstacle to possums
Lizards counted on predator free Kāpiti Island
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
