An area of forest lies inland from the road near to Bongabong, in the foothills below the eastern slopes of Mt Hitding. It was not visited during surveys in 1991, but when examined through binoculars from the road it appeared to be lowland forest. Very few signs of human encroachment were visible and the forest extended down to about 100 m altitude. Gradients were gentle on the lower slopes and forest extended to the mountain peak at about 1,000 m. There is thus a possibility that this is a surviving undisturbed forest extending from the lowlands to the mountain top.
Several of the threatened and restricted-range lowland forest species of the Mindoro Endemic Bird Area were collected in the Bongabong area in the past, with recent unconfirmed records of two of these species. If substantial areas of lowland forest are found to remain there, this IBA could prove to be one of the most important sites for the conservation of the highly threatened endemic lowland forest birds of Mindoro. The higher altitude forests on Mt Hitding could also support some of the endemic montane species.
Non-bird biodiversity: This IBA is also likely to support some threatened mammals, including endemic subspecies of wild pigs.
