Population justification: A survey in 2017 estimated the population at 160 (145-243) individuals, based on counts and maps of forested areas produced in 1986, with the caveat that the maps appeared to underestimate the amount of forest present, so the population estimates may be underestimates (Blanvillain & Patira 2017, C. Blanvillain in litt. 2017). This equates to approximately 107 (97 - 162) mature individuals. Notwithstanding the figure potentially being an underestimate, it is likely that the total number of mature individuals is less than 250 and is here placed in the band 50-249 mature individuals.

Trend justification: The results of surveys carried out in 1989-90 (Thibault & Varney 1991) and 2017 (Blanvillain & Patira 2017) estimate a population reduction from 274 (175-368) individuals in 1990 to 160 (145-243) individuals in 2017. This equates to a reduction of 21% across the last ten years (assuming linear decline and extrapolating to 2018), placed here in the band 15-25%.
