Population [top]
Population: The population size of this species has not been quantified, but it has been described as rare in general.
Trend Justification: Data on trends are lacking, but a moderately rapid population decline is likely to be taking place as a result of habitat loss, as well as pressure from hunting and trapping.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Yes
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: This species is poorly known, but most records come from between 300 and 1,000 m asl in primary lowland forest.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 19
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): This species is threatened by forest clearance for agriculture and logging, particularly given its strong links to unspoilt primary forest. It is also subject to pressure from hunting and trapping for trade.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
CITES Appendix II.
Conservation Actions Proposed
Conduct repeated surveys across the speciess range to determine the magnitude of declines and rates of range contraction. Campaign for the protection of remaining tracts of lowland forest throughout the speciess range. Monitor hunting and trapping pressure.
