Abstract

University of Mindanao is a private institution in the southern part of the country. One of its campuses located in Matina, Davao City is a 28 hectare campus that houses various flora and fauna. These biotic factors offer the community various service with ecological, aesthetics, historical and scientific significance. An inventory of angiosperms was conducted on June 2016 to January 2017 that aims to provide list of flowering plants, its conservation status and IEC materials. Purposive sampling at different sites within the campus was performed. All flowering plant species were photo-documented and were preliminary identified using Co’s Digital Flora of the Philippines, taxonomic keys, and comparing the works of Philippine botanists. Data mining was also conducted for the trees found in the campus. Results showed that there are 64 families of angiosperms composed of 195 genera and 277 species. Family Euphorbiaceae has the highest number of species identified with 20 genera and 25 species. Meanwhile, there are 40 families of trees found in the campus and is composed of 117 genera and 152 species wherein 84 species are exclusively found in the UM forest area. Most of the flowering plants found in the campus are introduced in the country. Among these plants, five (5) species are considered endemic namely: Carmona retosa (Vahl), Canarium ovatum (Engl.), Afzelia rhomboidea (Blanco), Ficus septica (Burm f.) and Ixora cv. While five (5) species are vulnerable namely: Aleurite moluccana (L.) Willd., Antidesma pleuricum Tul, Mallotus philippinensis (Muell), Cratoxylum formosum (Jack) Dyer and Dracontomelon dao (Banco) Merr and Rolfe. Moreover, a total of five (5) species are endangered namely: Mangifera odorata (Kwini), Cananga odorata (Lam) Hook f. & Thomson , Afzelia rhomboidea (Blanco) Vidal, Shorea astylosa (Foxworthy), and Shorea malibato (Foxworthy), and one (1) species is critically endangered, the Pterocarpus indicus (Forma echinatus) also known as Narra. It is recommended to preserve the flowering plants particularly the trees with the most concerned ecological status. The school community must develop consciousness and appreciation of the significance of the flowering plants to the school and the environment as a whole.
