Mangal or mangrove forests, seagrass beds, and coral reefs are the three major marine ecosystems that  were visited.

The trip began with the team planting mangrove seedlings by a brackish-water stream, followed by a quick survey of Morong's seagrass beds a vital nursery for juvenile fish and invertebrates, instrumental in binding sediments and producing nutrients. Long-spined and edible sea urchins blanketed the submerged meadow while shoals of rabbitfish and goatfish whizzed by. Along with the majority of Philippine seagrass beds, Morong's undersea meadows have so far proven resilient to human impacts.

WWF and the Manila Ocean Park have been partners since 2007 to further public awareness of the myriad issues faced by Philippine seas and to ensure that sustainable practices are adhered to at all times. Exhibits and educational modules are regularly conducted as an effective means to pique the curiosity of park guests, which number from 3000 to 5000 daily. Joint-initiatives such as the Morong immersion and a recent trip to observe whale sharks in Donsol, Sorsogon, are undertaken to hone both WWF and Manila Ocean Park's skills.

Manila Ocean Park's Allan de los Santos and May Tabayoyo accompanied Lim, while the WWF team was comprised of Obel Resurreccion, Ruel Bate, Audrey Revillon, Maye Padilla, Dino Calderon, and Gregg Yan. [via]
