New Zealand’s regional councils have just released a ‘think piece’ on the future of biodiversity management in New Zealand. “Our native flora and fauna is a taonga that does much to define us as a nation. It’s also under threat, and we are losing ground in many cases. This timely thinkpiece … [Read more...] about Regional Councils tackle biodiversity challenge
Sanctuaries and projects
Predator control for conservation purposes tends to focus on reserves, sanctuaries and remnants of native habitat rather than open pastures. When researchers publish articles on pastural predator control, they’re generally focused on possums and TB eradication. But landscape scale predator control … [Read more...] about Hawke’s Bay study shows predator control contributes to farmland biodiversity
The research happened a decade ago now – this paper was published back in 2008 – but how many people have even heard of the large, carnivorous Mercury Island tusked weta (Motuweta isolata), let alone the extraordinary story of its step back from the cliff-face of extinction? Despite its large … [Read more...] about How a tusked, carnivorous weta was saved
House mice are the smallest mammal predators to have been introduced to Aotearoa/New Zealand since humans first arrived here around 1280AD. The mice arrived on European ships by the 1820s and nowadays they are present in most habitats throughout the country. Worldwide they are among the world’s most … [Read more...] about Mice numbers in the absence of mammal predators
Public conservation land is only a small proportion of the total land of New Zealand and isn’t necessarily representative of the full range of ecosystems. David Norton (School of Forestry, University of Canterbury, Jason Butt (Environment Canterbury) and David Bergin (Environmental Restoration Ltd) … [Read more...] about Upscaling restoration – 8 things to consider
Passerines are songbirds which can perch. More than half of all bird species are passerines and many of those found in Aotearoa/New Zealand are unique. Some, such as the South Island saddleback, South Island robin and mohua also have a few other attributes in common: they’re rare, very vulnerable to … [Read more...] about Poor fliers reluctant to cross water
Predator Free Great Barrier or Stewart Island? It’s already technically feasible. But is it socially feasible? When it comes to complete eradication of predators on inhabited islands there’s a lot more to consider than just the conservation benefits and technical aspects. People, their livestock, … [Read more...] about Eradication – what about the social impacts?
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
In geologically ancient times, Banks Peninsula was a group of volcanic islands and even now is only connected to the mainland by a narrow strip of land. That makes the Peninsula of particular interest as a possible trial site for non-fenced mainland predator eradication. So could it be done? … [Read more...] about Achieving a predator free Banks Peninsula – costs revealed
Last year, when the NZ Government announced its Predator-Free 2050 goal, it also included some interim goals to be achieved by 2025 – now just eight years away. One of those goals is that: ‘by 2025 we will have eradicated all mammalian predators from New Zealand’s island nature reserves’. It … [Read more...] about PF 2025 interim goals – what will it take?
