Justification of Red List category
This species has a very small range, occurring on three very small islands. The largest population on Saipan is inferred to be declining as a result of habitat loss caused by commercial and residential development. The introduction of Brown Tree Snake (Boiga irregularis) to the species's range islands could result in very rapid elimination of the subpopulations on the islands and therefore, the species has very few locations. For these reasons, the species is listed as Endangered.
