Justification of Red List category
The majority of the population of this species occurs on the island of Saipan, where the Brown Tree Snake (Boiga irregularis
) may possibly be in the process of becoming established. This is likely to lead to an extremely rapid population reduction in the near future, unless the snake can be controlled. It therefore qualifies as Critically Endangered.
Distribution size (breeding/resident):
Land-mass type - oceanic island - Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth. Generally they have never been connected to a continental area by a land-ridge, and are volcanic in origin.
