Justification of Red List Category
This species is considered Near Threatened as it is suspected to be declining moderately rapidly throughout its range owing to the rapid clearance and degradation of lowland forests. The magnitude of these declines may be allayed by the persistence of populations in secondary growth and logged forests.
The global population size has not been quantified, but the species is described as fairly common to common (del Hoyo et al. 2007).
Data on trends are lacking, but declines are likely to be occurring as a result of habitat loss and degradation across the range.
Malacocincla malaccensis is known from the Sundaic lowlands, accurring in south Tenasserim, Myanmar; peninsular Thailand; Sabah, Sarawak and peninsular Malaysia; Singapore; Kalimantan (including Natunas and Anamba islands) and Sumatra (including offshore islands), Indonesia, and Brunei, where it is generally very common in suitable habitat.
This species occurs in lowland evergreen forest, including swamp forest, up to 1,000 m. Although it is most frequent in primary forest, it is also recorded from secondary growth, overgrown plantations, scrub and streamside thickets.
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 species's tolerance of logged forest and secondary habitats.
Conservation Actions Underway
Conservation Actions Proposed
Conduct repeated surveys within the range to identify population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Improve the management of any protected areas within the species's range that are suffering encroachment. Increase the area of suitable habitat that has protected status. Implement measures to reduce the number and severity of forest fires.
