Mostly we get rid of introduced predators by, well – killing predators. It works, up to a point. But if you can’t get rid of every single rat or stoat then the few survivors suddenly find themselves with ample food supplies and very little competition. They breed and they breed very successfully. … [Read more...] about Putting the case for ‘bottom up’
“Nearly 2 million tourists came to New Zealand last year.

Preserving, restoring and creating habitats for our wildlife doesn’t just mean planting trees and saving forests. It’s not just nature reserves and national parks. Braided rivers, sand dunes, alpine regions and wetlands – farmland and even urban gardens – are important habitats … [Read more...] about PCE Report – Birds need habitat and lots of it!
Developments in genetic science may give us the ultimate predator-free breakthrough one day, but we can’t sit back and wait for that to happen. “If we do,” warns Parliamentary Commissioner for the Environment, Dr Jan Wright, “the patient will die before the hospital is built.” Birds and other … [Read more...] about PCE Report – Research priorities and future promise
Jan Wright, Parliamentary Commissioner for the Environment, has written a comprehensive assessment of the current state of New Zealand’s birds – a taonga of our nation - and has made a number of recommendations for what needs to be done about the issues we face. “Of our 168 native bird species, … [Read more...] about PCE Report – Where’s the plan?
Last week Dr. Jan Wright released her penultimate report as Parliamentary Commissioner for the Environment. Titled “Taonga of an island nation”. It has been widely supported and will hopefully help focus our attention to save the species that desperately need our help. We will be delving into … [Read more...] about PCE Report — 5 Things You Need to Know
Lack of forest habitat or introduced predators – which is the biggest barrier to native biodiversity in New Zealand’s lowland landscapes? Can they even be considered separately? Is there any point in restoring habitat if you don’t get rid of predators and conversely, are there any benefits from … [Read more...] about Conserving biodiversity – what should be prioritised?
Wildling pines aren’t part of the mandate for Predator Free New Zealand but they are another serious invasive issue in many parts of New Zealand and research recently published in the Journal of Ecology (British Ecological Society) has revealed that some introduced mammals could be helping wildling … [Read more...] about Invasive mammals help invasive pines in surprising ways
What do we know about the effects of introduced mammalian predators in the alpine environment? The short answer is probably ‘not much’. DOC scientists Colin O’Donnell, Kerry Weston and Joanne Monks review the little that we do know in the latest volume of the NZ Journal of Ecology. They identify … [Read more...] about Alpine predator impacts little understood
Often when predators are eradicated from an island, it’s the first stage in planned reintroduction of native species to the sanctuary, but 26 years ago when the last introduced mammals removed from Burgess Island, the island was simply left, predator-free to recover naturally. Burgess … [Read more...] about Island recovery left to happen naturally
