Justification
This species in abundant within its relatively extensive range. It adapts well to human activity and development (e.g. it is found in rice paddies and canal systems). Although threats to this species include harvest for food and skin, these threats are not considered to be causing significant declines of this species. This species is therefore listed as Least Concern.
