This species is classified as Vulnerable because it has a very small population and is restricted to four very small islands, rendering it susceptible to stochastic effects and human impacts. If human disturbance or set-netting were shown to cause a population decline or fluctuations in numbers or locations, it would require uplisting to Endangered.
