SPECIES ACCOUNT OF MANGROVES IN THE COASTAL AREAS OF PANGAYAWAN, GITAGUM, MISAMIS ORIENTAL, PHILIPPINES
Authors: Liberty E. Taneo and Marilyn B. Areola
The inventory of mangroves in Pangayawan, Gitagum, Misamis Oriental was assessed for species composition, diversity, and dominance using the transect method. The vegetation in the area consisted of seven species: Avicennia marina, Avicennia rumphiana, Rhizophora apiculata, Rhizophora mucromata, Sonneratia alba, Lumnitzera racemosa and the mangrove associate Nypa fruticans. Rhizophoraceae species dominated the seaward zone while Nypa fruticans is a mangrove found only in landward zone. This was attributed to the mangrove's typical zonation pattern based on inundation and the common seedlings of Rhizophora species used in replanting activities in the area. The mangrove area in Pangayawan is relatively stable, with low human disturbance. The relatively low species diversity of the mangroves at Pangayawan, Gitagum, Misamis Oriental, needs to do intervention programs aimed to increase species richness. This is to achieve an ecologically-stable mangrove ecosystem that provides economic benefits to the community and to enhance the biodiversity of the coastal areas.
