Population justification: The global population is estimated at c.130 individuals, roughly equivalent to 87 mature individuals. |
|
Trend justification: The population was estimated at 100 individuals in 1998, climbing to 182 individuals by 2003-2004. However, the population declined following hurricane Ivan in 2004, with a maximum of 136 individuals estimated at 2007 (Rusk 2007). Although these figures suggest that the population may have increased between 1998 and 2007, this includes c.30 new individuals discovered in 2003, and increases may reflect an improvement in sampling methods. The population is thought to be undergoing a continued decline (B. L. Rusk in litt. 2010), estimated here at 1-19% over 10 years (three generations). |
