Population justification: The total population is estimated to number 2,500-20,000 individuals,and is thus best placed in the band 2,500-9,999 mature individuals. |
|
Trend justification: Some local extinctions have been recorded and the species as a whole is suspected to be declining at a moderate rate, owing to hunting, predation by dogs and habitat degradation (Coates 1985, Callaghan and Green 1993). |
