The little spotted kiwi (Apteryx owenii) was probably the most common kiwi species in Aotearoa/New Zealand in the mid-1800s. Now it's our second rarest kiwi of the 5 kiwi species. Numbers plummeted last century and it had almost disappeared from the mainland by the mid-1900s. Then 5 birds were … [Read more...] about DOC and volunteers count kiwi on Tiritiri Matangi
Sanctuaries and projects
Citizen science monitoring method outlined and tested
Monitoring wildlife population densities in our ‘mainland island’ fenced sanctuaries is an important part of measuring sanctuary success and assessing the longterm costs and benefits of predator-exclusion fencing. Such fences don’t come cheap, after all. What's the best way to monitor population … [Read more...] about Citizen science monitoring method outlined and tested
Study seeks future homes for kakapo
The kakapo population is outgrowing its island refuge – but where might future kakapo live? In a predator free future, the answer could include protected mainland sites provided there are sites that are big enough, safe enough and with the right kind of habitat for kakapo to thrive. If those likely … [Read more...] about Study seeks future homes for kakapo
Community groups under the microscope
Has your community group identified specific longterm conservation goals? What outcomes do you expect to see from the many hours of volunteer work that your team puts in? Have you thought about how your project contributes to the wider New Zealand Biodiversity Strategy? In a recent report … [Read more...] about Community groups under the microscope
Tree-climbing habits of predators studied
Many of NZ's introduced mammal predators – including house mice – are good at climbing trees. To understand the impact they have on tree-nesting birds and other tree-living wildlife, we need to learn more about how predators use vegetation compared with the ground. Mice aren’t commonly found in … [Read more...] about Tree-climbing habits of predators studied
Regional Councils tackle biodiversity challenge
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
Hawke’s Bay study shows predator control contributes to farmland biodiversity
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
How a tusked, carnivorous weta was saved
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
Mice numbers in the absence of mammal predators
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
Upscaling restoration – 8 things to consider
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
