Justification of Red List category
This species has a small known range, and thus probably has a moderately small population, which may be becoming increasingly fragmented. Population declines are inferred to be occurring as a result of habitat loss, although large tracts of suitable habitat remain secure at present. It is therefore currently considered Near Threatened.
10000-19999 mature individuals
Distribution size (breeding/resident):
Land-mass type - shelf island - Continental islands include all other islands or island groups. Generally they were once part of continents and lie on a continental shelf of < 200 m sea depth.
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.
