Justification This species is largely dependent on lowland evergreen forest within a region experiencing high rates of deforestation. Although it may be more tolerant of secondary habitats than some other hornbill species, it is likely to be declining moderately rapidly, and is therefore considered Near Threatened.

Range & population Anthracoceros malayanus is confined to the Sundaic lowlands of peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan and Sumatra (including the Lingga, Bangka, Belitung islands), Indonesia and Brunei. It is generally scarce or locally common in suitable habitat. Habitat loss has already driven it to the verge of extinction in Thailand.

Ecology: This species occurs in lowland primary evergreen forest, usually below 200 m. It is also found in selectively logged, gallery and swamp forest and tall secondary forest.

Threats Forest destruction in the Sundaic lowlands of Indonesia has been extensive as a result of commercial and illegal logging, conversion to agriculture (particularly plantations) and increasing human population pressure. This species's dependence on plains-level habitats places it at high risk, especially

Conservation measures underway CITES Appendix II.

Conservation measures proposed Monitor populations across the range to determine the magnitude of declines and rates of range contraction. Ensure the protection of remaining tracts of lowland evergreen forest throughout the Sundaic region.
