Flora

The Park has an amazing range of forest formations representing eight (8) of the thirteen (13) forest types found in tropical Asia, namely forest over ultramafic soils, forest over limestone soils, montane forest, freshwater swamp forest, lowland evergreen tropical rainforest, riverine forest, beach forest, and mangrove forest. Researchers have been able to identify more than 800 plant species from 300 genera and 100 families. These include at least 295 trees dominated by the dipterocarp type of species. In the lowland forest, large trees such as the Dao (Dracontomelon dao), Ipil (instia bijuga), Dita (Alstonia scholaris), Amugis (Koordersiodendrum pinnatum), and Apitong (Dipterocarpus gracilis) are common. Beach forest species include Bitaog (Calophyllum inophyllum), Pongamia pinnata, and Erynthia orientalis. Other notable plant species include Almaciga (Agathis philippinensis), Kamagong (Diospyrus pulganensis) Pandan (Pandamus sp) Anibong, and Rattan (Calamus sp.)
