Population justification:

Based on observations of 6 territories in <1km (Dowsett-Lemaire and Dowsett 1998b), and assuming that it inhabits 20% of the forest within its range (2,120 km² [Global Forest Watch 2021]), the population is estimated to be c.5,088 individuals, roughly equivalent to 3,392 mature individuals. However, the density estimate was obtained from the species’s stronghold, and it is less common elsewhere. Therefore, the population size is placed in the band 2,500-9,999 mature individuals.

Trend justification: The population is inferred to be declining in line with forest loss and degradation within the species's range. Between 2000-2019, this species's range experienced a 2.6% loss in forest cover (Global Forest Watch 2020). This equates to a loss of 1.7% over 3 generations. Tchoumbou et al. (2020) suggest that overall, the rate of deforestation in Cameroon is higher, at a 1% loss per annum. This would equate to a loss of c.12% over 3 generations for this species. Between 2016-2019, this species's range experienced forest cover loss of 1.1% (Global Forest Watch 2020). Projected forward over 3 generations this equates to a loss of 4.7%. If the rate of deforestation suggested by Tchoumbou et al. (2020) continues (at 1% per annum), that would equate to c.12% over 3 generations. Assuming the population declines at a similar rate, the rate of decline is placed in the band 1-15%.
