Justification of Red List category

This partridge has a disjunct distribution in lowland forest where conversion of forest to agriculture is rapid and on-going, and trapping pressure is prevalent. An apparent range contraction in the past two to three decades appears to leave it close to being extant in Malaysia only, although it is assumed to still be present in cross-border forests in Thailand. The subspecies T. c. atjenensis of Sumatra is likely to have become extinct during the last century. A rapid population reduction is suspected at a rate that likely slightly exceeds the rate of tree cover loss within the restricted elevation, which is 32% over the past three generations. The rate of population reduction is highly likely to continue to exceed 30% over the following three generations unless there is a sudden slowdown in the rate of habitat conversion. It is therefore classified as Vulnerable.

The total population is also now likely to be small and comprised of isolated subpopulations inferred to be undergoing continuing population declines. There is an overdue need for a range-wide sampling survey to generate a reliable population estimate, and for ongoing monitoring at key sites throughout the range.
