Table 3 Highlighted islands from the threatened island biodiversity database that support highly threatened vertebrate species, including those which are found nowhere else in the world.

These islands are uninhabited or minimally inhabited and contain at least one of the most damaging invasive species known (17). Consideration of these islands for invasive species management would deliver major impacts for the conservation of island species.
