Justification of Red List category
Although this species may have a small range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend is thought to be stable, hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but the species is reported to be common at higher elevations near Manokwari (Frith and Beehler 1998). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by only 1.6% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The population trend is therefore thought to be stable.
Trend justification
.
This species is endemic to the Arfak and Tamrau Mountains of the Vogelkop peninsula in north-west Irian Jaya, Indonesia (Frith and Beehler 1998).
The species is a rather poorly known inhabitant of montane forest, between 1,700-2,250 m (Frith and Beehler 1998).
The extensive rainforests within the species range remain largely undisturbed owing to their geographical isolation and the low density and traditional lifestyle of the human population, although deforestation is occurring in the hills of the Tamrau and Arfak mountain ranges (Sujatnika et al. 1995). Adult males are hunted locally for their skins (Gibbs 1993).
Conservation Actions Underway
There is one relatively substantial protected area in the Arfak and Tamrau mountains, the Pegunungan Arfak Nature Reserve, which currently covers 683 km2 but has been proposed for extension (Stattersfield et al. 1998). In addition there is a huge protected area proposed for the Tamrau mountains, the Pegunungan Tamrau Nature Reserve (Sujatnika et al. 1995).
