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)?
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’
Why did they do it? What possessed New Zealand’s government of the day, its citizens and acclimatisation societies to introduce rabbits and then stoats? It’s easy to judge in hindsight. But perhaps we should do more than judge. A better understanding of what they were thinking at the time might … [Read more...] about Liberation of stoats and weasels – a look back in time
Kea numbers are decreasing. Nesting adult females, their eggs and chicks are highly at risk from mammal predators. But are there other, invisible risks too? Extinction risk isn’t simply a numbers game – it’s not just the population size of a species that indicates whether it’s at risk of becoming … [Read more...] about Genetic diversity – what do we know about kea?
“Nearly 2 million tourists came to New Zealand last year. Few if any came to go shopping,” says Parliamentary Commissioner for the Environment, Dr Jan Wright, in her newly released report. “Wilderness is becoming increasingly scarce around the world, and in scarcity lies value,” she … [Read more...] about PCE Report – More $$ for conservation, more support for groups
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
Kiwi call counts are an important monitoring tool in kiwi recovery projects, but just how accurate are they? The time of night you choose, the weather, the season and other environmental factors can all potentially affect kiwi calling and best practice recommendations have been formulated to reflect … [Read more...] about Study investigates kiwi call count parameters
