This species is classified as Vulnerable because it has a small range and is restricted to a small and decreasing number of colonies. Although it is known to abandon and reoccupy sites over decades, the loss of a comparatively large number of locations in recent years is of concern, and although population trends are unclear, the population may be declining.
