Population [top]
Population: The population size of this species has not been quantified, but it is described as common.
Trend Justification: Evidence of increasing human population pressure and development within the speciess range suggests that slow declines are likely to be occurring.
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 inhabits monsoon forests in lowlands and hills, where it is described as common.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 2.8
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): Although its range is very small, forested habitat is relatively intact on the Andamans and insufficiently disturbed or fragmented to be of immediate concern. However, there are signs that pressure on forests is increasing on the islands through increasing human populations and consequent conversion of habitat to cultivation, grazing, increased logging and development.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.
Conservation Actions Proposed
Monitor rates of population change and habitat trends. Conduct ecological studies to determine habitat requirements, tolerance of secondary habitats and response to fragmentation. Ensure the protection of remaining forest habitats on the Andaman Islands.
