Many New Zealand species are already at risk because of predators and habitat loss—climate change makes things worse

Islands are biodiversity hotspots. They are home to 20% of the world's plants and animals yet cover only 5% of the global landmass. But island ecosystems are highly vulnerable, threatened by habitat fragmentation and introduced invasive weeds and predators. Climate change adds to all these stresses. In our recent paper, we use Aotearoa New Zealand as a case study to show how climate change accelerates biodiversity decline on islands by exacerbating existing conservation threats.
