Justification of Red List category
This species qualifies as Vulnerable because it has a small population which is suspected to be in decline. It has been eliminated from some sites by a combination of predation by introduced fish and entanglement in monofilament gill-nets, and is suffering habitat loss to rice cultivation, and the rate of decline is likely to accelerate in the next 16 years (three generations). It has been suggested that the population size is now very small, and should this suspicion be confirmed the species may warrant uplisting in the future.
