This species has a wide range, however, it has a fairly small population. Threats at present are unknown, but if threats were identified it seems reasonable that this species could qualify for listing as Vulnerable under criterion C1 if there was a continuing decline of 10% over the next 30 years. The species is therefore listed as Near Threatened.
