Site description The adjacent peaks of Mt Pasian and Mt Agtuuganon are in eastern Davao del Norte Province, extending just across the border into Davao Oriental. They rise to 1,652 and 1,404 m respectively. There is montane forest, including mossy forest, around the peaks of both mountains, and some areas of lowland forest on their lower slopes. The northern portion of Mt Pasian is in the PICOP Concession, and the logging company has protected the forest there, which remains pristine. An area of primary lowland forest at 450 m within the Community Forest Program (PFP) area at Mantunao, to the east of Mt Agtuuganon, is included in the IBA. There are small communities of Mandayas in these mountains, who practice slash-and-burn agriculture and plantation farming on the more accessible flatter slopes. The PICOP Resources logging company has built an access road along the north-south ridge leading to Mt Pasian, where PICOP and the Philippine Long Distance Telephone Company (PLDT) have built radio and telephone relay stations.

Key Biodiversity Several of the threatened and restricted-range species of the Mindanao and Eastern Visayas Endemic Bird Area have recently been recorded on Mt Agtuuganon and Mt Pasian, including lowland and mid-altitude forest specialists such as Lesser Eagle-owl, Miniature Tit-babbler and Little Slaty Flycatcher. The newly described Lina's Sunbird, which is so far only known from one other site, the Mt Puting Bato-Kampalili-Mayo complex (PH088), is common in the montane forests in this IBA. There are recent records of Philippine Eagle, and the forests on Mt Agtuuganon and Mt Pasian are probably an important part of the network of sites required for the conservation of this critically endangered species.

Non-bird biodiversity: The mammals of the area are unknown.
