The Philippines has secured a major ecological victory with the induction of Mindoro’s Apo Reef Natural Park into the ASEAN Heritage Parks network, a move that exhibits the critical importance of marine conservation in one of the world’s most biodiverse regions.

Situated west of Sablayan in Occidental Mindoro province, the Apo Reef Natural Park spans 27,469 hectares and represents a marine ecosystem of global importance.

As the second-largest contiguous coral reef system in the world and the largest in the Philippines, the park is a crucial sanctuary for marine biodiversity facing unprecedented environmental threats.

The reef hosts an astounding 482 fish species, 63 genera of hard corals, and supports critically endangered marine species including Green Sea Turtles, Hawksbill Turtles, Dugongs, Whale Sharks, and Hammerhead Sharks. Its ecological importance extends beyond mere species count, serving as a critical breeding ground and marine habitat in the rapidly changing Southeast Asian marine environment.

The ASEAN Centre for Biodiversity (ACB) officially recognized Apo Reef as the 61st ASEAN Heritage Park, alongside two other Philippine sites—the Turtle Islands Wildlife Sanctuary and Balinsasayao Twin Lakes Natural Park. This brings the total number of protected areas in the ASEAN network to 62, representing 11.6 million hectares of vital ecosystems.

“For four decades, the ASEAN Heritage Parks Program has remained a testament to regional cooperation and commitment to preserving our natural wealth,” said ACB Acting Executive Director Clarissa Arida.

The designation provides opportunities for enhanced protection, research, and cross-border conservation efforts.

The Philippines sits within the Coral Triangle, a marine region recognized as the global center of marine biodiversity.

Mindoro, in particular, plays a crucial role in this ecological landscape.

The Apo Reef’s recognition comes at a critical time when marine ecosystems face unprecedented threats from climate change, ocean acidification, overfishing, and pollution.

Marine experts estimate that the Philippines has lost over 50% of its coral reefs in recent decades, making conservation efforts like the ASEAN Heritage Parks Program crucial for sustainable marine management.

The Apo Reef represents a beacon of hope, showcasing the potential for ecosystem recovery and preservation.

Local communities in Occidental Mindoro have increasingly become involved in marine conservation efforts, recognizing the reef’s economic and ecological importance.

Sustainable tourism, regulated fishing, and community-based conservation programs have emerged as top strategies for protecting this marine treasure.

The induction of Apo Reef into the ASEAN Heritage Parks network is more than a bureaucratic achievement—it’s a critical step in protecting one of the planet’s most important marine ecosystems.
