The flora of Nauru

The recorded flora of the raised phosphatic limestone island of Nauru in the equatorial Pacific Ocean consists of approximately 493 species. Only 59 are possibly indigenous, none of which are endemic. The balance is composed of ornamentals, weedy exotics, food plants, and a limited number of other useful cultigens. Twelve of the recorded species are either extinct or were never successfully established on Nauru. Long human settlement, expansion of coconut monoculture during the colonial period, widespread destruction during World War II, and almost a century of open-cast phosphate mining, have led to serious vegetation degradation, disturbance, and displacement
