Site description Described as “steep mountains and hills covered in rather stunted ultra basic forests, disturbed in the lower parts but quite well formed on the summits” (FAO/UNDP (1982). This area was considered one of the three highest priorities for conservation of biodiversity in Timor-Leste by FAO/UNDP (1982), and with high socio-economic value such as watershed maintenance. Known in Indonesian as ‘Hutan Querelau Lauberio’ (RTK 11) (Ora 2000). The habitat is described as semi-evergreen monsoon forest, locally heavily degraded and now mostly confined to the upper ridges, with grazed Eucalyptus woodland elsewhere on the ridges (Mauro 2003).
Key Biodiversity Fourteen restricted-range species have been recorded in this IBA, including the Endangered Timor Imperial-pigeon and Timor Green-pigeon, and the Critically Endangered Yellow-crested Cockatoo also occurs there (Mauro 2003).

Protection status Proposed as a Nature Reserve by FAO/UNDP (1982). According to Ora (2000), the entire site was subsequently gazetted as a Nature Reserve (SK Menhut No. 663/Kpts-II/1996), and the Indonesian Forestry department also recommended that this site be a National Park, a proposal which was supported by the then Governor of East Timor. The summit and surrounding forests were recognised by UNTAET (2000) as a Protected Wild Area under Regulation Number 2000/19.
