Population justification: Given that the only estimations for any one of this species's subpopulations are for no more than 1,000 individuals, e.g. central Mozambique and the Udzungwa Mts (L. Hansen in litt. 2007), the total population is placed in the range band for 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend justification: The population is suspected to be declining, owing primarily to the clearance, degradation and disturbance of habitat across its range. The likely rate of decline has not been calculated.
