Population justification: The population is estimated to number 250-999 individuals (G. Servat in litt. 1999, G. Engblom in litt. 2000). This equates to 167-666 mature individuals, rounded here to 150-700 mature individuals.
Trend justification: This species's population is suspected to be experiencing a moderate and ongoing decline, in line with habitat loss and degradation within its range.
