Population justification: The total population is estimated in the range 2,500-9,999 individuals based on data given by Forboseh and Ikfuingei (2001). This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: This species's population is suspected to be decreasing rapidly, in line with habitat loss and degradation within its range.
