Site description (2001 baseline)
The Bulosao Watershed Forest Reserve is adjacent to the MacArthur Mountains, and straddles the boundary of Samar and Eastern Samar Provinces. The highest peak in the IBA is Mt Honop at 731 m. The northern and western boundaries of the IBA approximately follow the Sulat River. Closed canopy lowland dipterocarp forest covers c.2,624 ha (65%) of the watershed, open canopy lowland dipterocarp forest covers c.952 ha (24%), cultivated areas with brush cover c.208 ha (5%), coconut plantations cover c.171 ha (4%) and contract reforestation plots (planted with exotic tree species) cover c.100 ha (2%). There are a few small settlements present in the area, and the small patches of agricultural land and kaingin are planted with coconut, banana and fruit trees.

Key biodiversity
The avifauna of the Bulosao River Watershed Forest Reserve is virtually unknown, but it is likely to be similar to those of the other IBAs on Samar, the Mt Cabalantian-Mt Capotoan complex (PH073) and the Mt Yacgun-Mt Sohoton complex (PH074). The extensive forests in this IBA therefore probably support important populations of several of the threatened and restricted-range species of the Mindanao and Eastern Visayas Endemic Bird Area.
