About 49% (approximately relatively few establishments compared to other sites which 2.58 ha) of the mangrove swamp was developed into a composed of native cottages, 12 souvenir mini-shops and residential area by the claimants. The natural creek which one restaurant located at the entrance of the beach. previously connected the mangrove swamp to Puka Beach was covered due to developments. The remaining Site 3 is the Bulabog Beach, or the back beach at undeveloped portion of the area [51% (2.73 ha)] is a Balabag Village (Figure 2). It is located at 11 58’37.5”N; o forested wetland containing mangrove forest. It serves as 121 58’37.5”E. The beach is mostly covered by the vast Figure 2.

Inventory of Flora and Fauna Marine Species Inventory Most marine species enlisted are labelled with a conservation status of ‘least concern’ in the International Union for the Conservation of Nature (IUCN). However, species such as parrot fish are already considered as near threatened; sea stars threatened; and puffer fish vulnerable. Parrot fishes have been proven to have significant ecological importance in a way where it consumes algae and dead corals; in return, it excretes large amount of sand deposits which help prevent coastal erosion and help build up the sea bed. Meanwhile, sea stars and puffer fish help alleviate marine algal population by consuming them.
