Vostok Island

Year of compilation: 2007

Site description
Vostok is a small, low-lying, coral island of the southern Line Islands.

Key biodiversity
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.

Protected areas
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.
