Justification of Red List category
This species qualifies as Endangered because it is restricted to four very small islands, including Saipan, where brown tree snake Boiga irregularis may be in the process of becoming established, and Tinian and Rota where the snake has also been detected. These three islands support 97% of the population. It formerly occurred on Guam, where it was extirpated by brown tree-snake. It is therefore very likely to undergo a rapid overall population decline in the immediate future. Fortunately, there has been little evidence of brown tree-snakes colonising any islands outside of Guam, and this species might be down-listed after a more detailed assessment of this threat.
