Plants, pests and diseases
New Zealand plant biodiversity is recognised for its richness, distinctiveness of species and unique assemblages. This national treasure has enormous social and economic value and is integral to the healthy function of our natural ecosystems and the beauty of many of our landscapes.
When plants turn bad
Understanding how and why plants make the transition to weedy species, often after long lag times, is one of the aims of an ambitious new research project.
Weeds a ticking time bomb
Tomorrow’s weeds are already here in New Zealand and experts warn they’re a time bomb waiting to explode.
Fresh thinking in the fight against Tb
A world-first effort to develop a vaccine to make possums immune to tuberculosis (Tb) could one day be an effective tool for reducing the levels of this problematic disease in livestock both in New Zealand and overseas.
Slowing varroa’s deadly march
The varroa bee mite has caused significant damage to New Zealand’s honey production since it was first discovered in 2000 but research has highlighted unique aspects of the mite’s biology and behaviour that could be used in the fight against it.
Landcare Research is spearheading work to help understand and halt the spread of a destructive disease that is killing one of New Zealand’s iconic native tree species, the kauri.
