This species is classified as Endangered because it has a very small population which is likely to be in decline owing to habitat loss and degradation.

Geographic Range [top]

Range Description: Apalharpactes reinwardtii is known from just six forested mountains in West Java, Indonesia: Gunung Halimun, Gunung Salak, Gunung Gede-Pangrango, Gunung Patuha-Tilu, Gunung Wayang and Gunung Papandayan. There are only recent records from three of these (Halimun, Salak and Gede-Pangrango). The historical range totals 11,600 km2. Although it has been stated to occur from 800-2,600 m, little forest remains below 1,000 m away from Halimun, and the species appears to be rarer at higher elevations. The only site where the species appears to be common now is Gunung Halimun, but only at lower elevations. The population size of this species may be as low as a few hundred pairs (Collar and van Balen 2002).

Population [top]

Population: The population size has been estimated to be as low as a few hundred pairs. It is thus placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It appears to favour mid-montane forest, where it feeds on a variety of invertebrates taken by aerial sallying or by perch-gleaning. It also feeds on fruit and will occasionally join mixed-species flocks (del Hoyo et al. 2001).

Systems: Terrestrial

Threats [top]

Major Threat(s): Forest loss, degradation and fragmentation, through widespread agricultural encroachment and localised development (e.g. holiday resorts and geothermal projects), are increasing threats in the species's altitudinal range.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
The species has been recorded in Gunung Halimun and Gunung Gede-Pangrango National Parks.

Conservation Actions Proposed
Conduct further surveys for the species at all mountains potentially within its range to clarify its current distribution and population status. Propose key sites for designation as protected areas, or as extensions to existing reserves. Work with local authorities and relevant companies to minimise the impact of tourism and development projects on forested mountains within its range.
