Site description Mt Hilong hilong lies on the boundaries of Agusan del Norte, Agusan del Sur and Surigao del Sur Provinces, in the northern portion of the Diwata range of north-east Mindanao. It is the highest mountain in the range, but several of the other peaks included in the IBA also reach well over 1,000 m. The IBA comprises a large block of forest that is shown on recent forest cover maps. Much of this forest is montane, but there are also likely to be some substantial areas of lowland forest. The Cabadbaran-Santiago Natural Park is located on flat to rolling land from 200-1,700 m. It includes c. 3,002 ha (58%) of residual forest, including a 120 ha rattan plantation established by the DENR, c. 1,682 ha (33%) of brushland with medium-sized trees and c.318 ha (6%) of grassland. Cultivated land covers c.163 ha (3%), and is planted with corn, root crops and fast-growing exotic tree species, such as yemane or gmelina Gmelina arborea. Cabadbaran-Santiago Natural Park was declared as a forest watershed reservation because it is the main source of water for the municipalities of Cabadbaran and Santiago. A 500 ha area has been set aside as ancestral domain.
