Vostok is a small, low-lying, coral island of the southern Line Islands.
An important seabird colony.
Non-bird biodiversity: Coconut crabs have been positively identified on the island, although densities are unknown.
Pressure/threats to key biodiversity
There is a substantial population of pacific rats on the island, particularly underneath the Pisonia woodland. Little evidence that the rats impact significantly on the seabird populations however.
Vostok Island has been a restricted-access Wildlife sanctuary since 1979.
Habitat and land use
Little evidence of recent occupation. Phosphate mining was proposed, although there is no evidence that any extraction actually occurred. A small triangular island with no lagoon, the central portion of the island is occupied by a stand of Pisonia forest which grows to a height of c25m.
