In a remote part of the West Philippine Sea, a unique ecosystem is doing critical work. This area captures carbon from the air and supports coastal plants. A recent study by the Department of Environment and Natural Resources-Ecosystems Research and Development Bureau (DENR-ERDB) highlights this amazing beach forest ecosystem on Pag-asa Island.
The researchers discovered that this 32-hectare forest holds nearly 10,000 tons of carbon dioxide. That’s the same as the annual emissions from about 2,000 cars. The forest also hosts native vegetation that is essential for keeping the shoreline stable and helping the island resist climate changes.
This finding is crucial as it emphasizes the importance of coastal forests in battling climate change and preserving biodiversity. These ecosystems serve as natural barriers against rising seas and storms, especially as environmental pressures increase in the West Philippine Sea.
The study listed 20 plant species, including strong coastal trees like Barringtonia asiatica (botong), Calophyllum inophyllum (bitaog), and Terminalia catappa (talisai). Despite having a limited number of species, the forest is noteworthy for its ability to store carbon, thanks to its tall, sturdy trees.
“Pag-asa’s beach forest may be small, but it has a huge ecological impact,” said Jose Alan Castillo from ERDB. He noted that these large trees serve as nature’s carbon lockers and protect against coastal storms. Interestingly, Barringtonia asiatica alone makes up 85% of the island’s carbon storage.
However, the forest is shrinking. The researchers found its vegetation cover decreased from 11 hectares in 2017 to less than 7 hectares in 2023. This alarming trend highlights the urgent need for action to protect these vital ecosystems.
Beach forests, often overshadowed by mangroves and coral reefs, are just as crucial for stabilizing shorelines and regulating climate. The team recommends including beach forest conservation in the National Greening Program and other climate action plans.
The insights from this study serve as a stark reminder that even small islands like Pag-asa can play a significant role in climate action. Protecting these forests can help us work towards a more sustainable future.
