This IBA includes the low mountains between Mt Yacgun and Mt Sohoton, which straddle the border between Samar and Eastern Samar Provinces. It lies between the Mt Cabalantian Mt Capotoan complex (PH073) to the north and the Bulosao River Watershed Forest Reserve (PH075) to the south. Mt Sohoton is characterised by rugged to rolling terrain with numerous boulders and limestone deposits and an extensive cave system. There are some patches of remnant dipterocarp forest and secondary forest on Mt Sohoton, and together with Mt Yacgun it forms the second largest block of forest shown on recent forest cover maps on Samar. This forest block is mostly composed of closed canopy lowland dipterocarp forest. The Mt Yacgun-Mt Sohoton Complex is an important watershed area, and five rivers flow down from it into the surrounding lowlands.
Several of the threatened and restricted-range species of the Mindanao and Eastern Visayas Endemic Bird Area have been recorded in or near to this IBA, including Philippine Eagle. The relatively extensive forests which remain there are likely to prove to be an important site for the conservation of this and other threatened species. There are recent records of the critically endangered Philippine Cockatoo in the IBA, and this is the only site on Samar where the poorly known Miniature Tit-babbler has been recorded.
