Population justification: The species occurs at low densities; distance sampling along transects found on average 4 individuals/km2 (Devenish et al. 2020). Multiplying local densities by the area of suitable habitat at a site yielded a minimum population estimate across the study area of 1,575 (95% CI: 638-3,185) individuals (Devenish et al. 2020). This roughly equates to a minimum of 1,000 mature individuals and therefore, the overall population is here placed in the band 1,000-2,499 mature individuals.
Trend justification: Habitat degradation within the range is suspected to be driving a slow population decline. The rate of decline has not been quantified, but is unlikely to exceed 10% over ten years.
