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

Burgess … [Read more...] about Island recovery left to happen naturally
A huge effort has gone into controlling possums across New Zealand for a number of years, particularly with respect to TB eradication efforts, but what do we know about the overall biodiversity outcomes? Are we on top of the problem? Has native biodiversity benefited long-term from the war waged … [Read more...] about Measuring biodiversity outcomes
Landcare Research scientists have published some fascinating research recently looking at the damage possums do the forest canopy and the surprisingly long time it takes for larger trees to recover. The first paper was published in Ecology and Evolution earlier this year and full access is freely … [Read more...] about Landcare Research takes to the tree tops in latest possum research
If we knock back ferrets and feral cats will rabbit numbers soar? It is a concern that’s frequently raised, particularly in farming areas where rabbit control is already an issue. As rabbits are the main prey of ferrets and feral cats, it seems intuitively logical that rabbits will thrive without … [Read more...] about What about the rabbits?

Recently … [Read more...] about Maungatautari – a Maori conservation perspective
