Justification of Red List category
This species is precautionarily maintained as Near Threatened because in the past it has undergone substantial declines in its population size. Present knowledge suggests that these declines are historical and the species is now increasing in parts of its range. While the population trend has been positive over the last three generations, this was largely due to successful conservation action. The species remains highly conservation-dependent, and the cessation of conservation action would likely lead to a rapid deterioration in status and a listing under a threatened category. Moreover, it is feared that the species may potentially decline in the future, as the impacts of climate change may degrade its wetland habitats.
