Abstract

PRECY ANN MAE D. REYES

Mangroves are salt-tolerant trees adapted to salty and brackish water environment. The decline of mangrove areas due to over-exploitation and unsustainable use has been a worldwide catastrophe. Thus, this study was conducted to determine the distribution and abundance of mangrove species which will serve as a baseline data for future research. The study was conducted at the landward, middle ward and seaward zones of Cagbaoto, Bayabas, Surigao del Sur where it employed a purposive sampling method. The study revealed 8 species of mangrove belonging to 8 families. It had shown that Acanthus ebracteatus was the highest in terms of species abundance (30.43%) and Aegiceras floridum was the lowest (1.45%). Bruguira cylindrica and Exoecaria agalloca were found across all zones but there were also species that only grow on seaward zone. Based on the study, it can be concluded that there were specific species that dominated in terms of their abundance on each zone and evidently shown their distribution across all zones.
