Recently there have been several research projects looking at predators in the alpine environments of the South Island. It’s a completely different ecosystem to the much-studied lowland forest systems and there’s still a lot to be learnt about the key predator threats to our alpine species and how … [Read more...] about Latest research from Otago University and DOC investigates rock wren and 1080
The interaction between habitat restoration and predator control is a topic of great interest to us at Predator Free NZ Trust. In 2017 Manaaki Whenua Landcare Research created a series of info-graphics that looked at just that. Focusing on the Cape to City Project, they asked what do bird … [Read more...] about What do bird populations need to thrive?
Control possums, rodents and large introduced grazers and the forest understorey explodes with growth. It’s easy to think that this is what the original forests of Aotearoa must have looked like, before Man and other mammals arrived. But ancient Aotearoa had its own large herbivores – the various … [Read more...] about Moa vs Deer – are they so different?
Insects get eaten too. Scientists have reported that invertebrates have been found in 10-30% of cat guts and scats in the Mackenzie Basin, suggesting high country invertebrates, including some rare endemic grasshoppers, could be vulnerable to introduced mammal predators. Christchurch-based … [Read more...] about Insects get eaten too – so does predator control help grasshoppers?
It’s a world-wide trend and New Zealand is not immune. Wetlands are being lost – 90% of New Zealand’s wetlands have disappeared since European settlement. “Freshwater swamps, bogs, gumlands, pākihi, fens, marshes and seepages, are estimated to have occupied 9% of the New Zealand land mass or … [Read more...] about Loss of wetlands continues
You don’t hear so much about weasels. Their New Zealand distribution is patchy and their bigger mustelid relatives tend to dominate the mammal predator stories. But when there was a mast year in 2014, weasels as well as stoats turned up in the beech forests of Nelson’s Maruia Valley to feast on the … [Read more...] about Weasels studied during Maruia masting event
Researchers from Landcare Research and Tūhoe Tuawhenua Trust recently worked together to look at community-based monitoring by Māori to assess forest health. They talked with 55 forest users from the Tuawhenua tribal group, carrying out 80 interviews in both Māori and English, over a period of 10 … [Read more...] about Tūhoe share memories of how their forests used to be
Weka don’t tend to be the first bird chosen for reintroduction in recovering habitats. Their destructive and predatory tendencies make them controversial residents in restoration projects and they’ve even been removed from some sanctuary islands to make life safer for other native birds. But new … [Read more...] about Time to rethink the weka’s bad-boy image
We know a lot about the impacts of introduced mammal predators in wild environments and about how to control their numbers in forests and remove them entirely from uninhabited islands. What we don’t know so much about, is the lives and impacts those predators in places where people also … [Read more...] about Managing predators where people live too
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
