Justification of Red List category
This species has a very small and fragmented population as a result of habitat loss, hydrological changes, hunting, disturbance and potentially a number of unknown factors, and is projected to undergo an extremely rapid population decline over the next three generations (25 years) owing to these on-going threats. It therefore qualifies as Critically Endangered. If conservation efforts succeed in bringing the largest remaining populations, in north-eastern Cambodia and along the Mekong channel, under effective protection and predicted rates of decline are therefore lower, the species may warrant downlisting.
