Site description This IBA includes the forested sections of the mountainous Agustin Peninsula in the south-east of Mindanao. This long, narrow peninsula rises to a maximum altitude of 1,641 m at Tumadgo Peak. Extensive lowland and montane forests are shown on a recent forest cover map on the eastern side of the peninsula, extending southwards from the area around Tumadgo Peak and Tumadgo Point. A survey in 1997 located areas of selectively-logged lowland forest at 0-660 m within the Davao Enterprises Corporation concession at Cabuaya, selectively-logged lowland forest at 650 m at La Union and degraded lowland forest and selectively-logged montane forest at 665-1,100 m at Sergio Osmeña.
