Population justification: Fontaine (2003) suggests its population is 'not more than a few thousand individuals', and so it is tentatively placed in the band 1,000-2,499 individuals here. This is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals. This value however requires confirmation, and the species may be less rare than previously thought, as its preferred habitat is mainly inaccessible and records are sparse (Fontaine 2003).
Trend justification: The population is suspected to be overall stable. Although there is the potential threat of swamp drainage (Urban et al. 1997), the species is present within a number of protected areas across its range, and the inaccessibility of its preferred habitat likely provides an additional level of protection.
