Population justification: The species's population has been estimated to number 5,000-10,000 individuals (T. Dodman in litt. 2002), roughly equivalent to 3,300-6,700 mature individuals. |
|
Trend justification: The population is estimated to be either declining (Wetlands International 2002, Dodman 2008, Delany et al. 2009), or stable following a major decline (T. Dodman in litt. 2007). Declines are presumably linked to widespread loss and degradation of wetland habitats in Madagascar (Delany et al. 2009). |
