Islands are renowned for their weird and wonderful wildlife. These isolated ecosystems present unparalleled opportunities to study evolution, and the archipelagos of the southwest Pacific are no exception.
This vast and diverse region encompasses 24 nations and territories. It also includes four “biodiversity hotspots”: the East Melanesian Islands, Polynesia-Micronesia, New Caledonia and New Zealand. Each contains at least 1,500 plant species found nowhere else on Earth. So their total land area may be small, but south-west Pacific islands punch well above their weight in terms of their contributions to global biodiversity.
