Justification:

This species has a disjunct distribution in lowland forest where logging is rapid and on-going, and trapping pressure is prevalent. It is likely to be undergoing a moderately rapid population reduction and is consequently classified as Near Threatened.

History:

2008	–	Near Threatened
2004	–	Near Threatened
1996	–	Vulnerable
1994	–	Vulnerable

Geographic Range [top]

Range Description:	Arborophila charltoni has a disjunct, mainly Sundaic distribution ranging (race charltoni) from southern Myanmar and southern Thailand into Peninsular Malaysia, and is present (race atjenensis) in two isolated areas (Aceh and South Sumatra) of Sumatra, Indonesia, and occupies a wide area of Sabah (Borneo), Malaysia (race graydoni) (BirdLife International 2001). An outlying population (race tonkinensis, formerly treated under Green-legged Hill-partridge A. chloropus) occurs in east Tonkin and north Annam, Vietnam. Estimates of numbers are of possibly under 10,000 (100-10,000) (charltoni), 10-100 (atjenensis), 100 (graydoni), with tonkinensis locally quite common and in three protected areas. Graydoni is now known to be quite common in Danum Valley, Sabah.

Population [top]

Population:	The global population size has not been quantified, but the species is described as very rare in Sumatra and almost extinct in Thailand. The nominate race is thought to number 1,000 individuals (del Hoyo et al. 1994).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This species inhabits lowland forest to 500 m. It is noted to be scarcer in logged forest.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Forest destruction in the Sundaic lowlands of Indonesia and Malaysia has been extensive (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998). Declines caused by habitat loss are compounded by trapping for the cage-bird trade. However, the species's use of secondary growth and higher elevations implies that it is not immediately threatened.
