Population justification: The population is estimated to number 210-278 individuals, roughly equating to 140-190 mature individuals.
Trend justification: From 50-60 individuals on La Digue in 1978-1988 (Watson 1981, 1991) the species's population size doubled by 1997 (Rocamora 1997, Currie 2002, 2003). More recently it appears to have stabilised at 150-200 individuals. However, should the newly-established population on Denis Island prove viable, the total population will continue to increase.
