In the Pacific, ecosystems hang in a delicate balance. The isolation of Pacific islands lends them a natural protection from invasive species that continental ecosystems don’t have. But when an alien species does alight on these remote shores, they can wreak havoc.
Invasive species are the number one cause of extinction of single-country endemic species in the Pacific. 5.8 per cent of the Pacific’s 2,189 single-country endemic species are already extinct. 45 per cent are at immediate risk.
