Justification of Red List category
Although this species has a large population, it qualifies as Near Threatened because of its tiny range and fears that the Brown Tree Snake Boiga irregularis could become established on its main range island (that hosts >99% of the global population), which could result in a moderately rapid population reduction. The risk of more rapid population reductions is mitigated by the presence of a Brown Tree Snake barrier at Tinian Port, with all planes, vessels and cargo subject to inspections, as well as snake traps maintained on fence lines surrounding ports of entry, and a taskforce able to respond to reports of snakes.
