Population [top]
Population: The population size of this species has not been quantified.
Trend Justification: Moderate declines are suspected to be occurring, particularly in lowland parts of the range, as a result of deforestation.
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 occurs in the middle stratum and understorey of lowland and hill forest up to 1,500 m (1,700 m on Borneo). It inhabits only closed-canopy forest, but can occur in regenerating logged forest.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 6.6
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): Rates of forest loss in the Sundaic lowlands have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect (particularly in 1997-1998). The magnitude of these threats may be allayed by this speciess tolerance of hill forest, which is under less pressure from logging and agricultural conversion.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species.
Conservation Actions Proposed
Conduct repeated surveys across the range to estimate population trends and rates of range contraction. Ensure the protection of remaining tracts of primary lowland rainforest throughout the range.
