Volunteers join UNESCO eDNA
sampling in Tubbataha Reefs in
Philippines
Tucked in the heart of the Sulu Sea, Tubbataha Reefs Natural Park is one of the most pristine marine ecosystems in the Philippines, recognized as a UNESCO World Heritage Site since 1993. In April 2023, young volunteers from across the Philippines embarked on an exciting scientific expedition led by UNESCO to collect environmental DNA (eDNA) samples. This cutting-edge initiative sheds light on the biodiversity richness of UNESCO eDNA Sampling Tubbataha Reefs while demonstrating the potential of eDNA as a non-invasive method to monitor marine life.
This article delves into the eDNA project, its significance for conservation, and why Tubbataha Reefs stands out as a beacon for sustainable marine management and one of the best diving Philippines destinations, easily accessible on routes like Coron to El Nido.

What is UNESCO’s eDNA Initiative?
UNESCO’s environmental DNA (eDNA) initiative is an innovative approach to studying ocean biodiversity. By analyzing DNA traces left behind by organisms in water samples, researchers can gain a snapshot of the genetic material present in marine environments.
Why eDNA Matters
- Non-Invasive: Unlike traditional methods that involve capturing and extracting organisms, eDNA sampling minimizes disruption to ecosystems.
- Cost-Effective: A single liter of water can reveal the presence of hundreds of species, making it a valuable tool for biodiversity research.
- Climate Change Insights: Combining biodiversity data with climate projections provides a glimpse into how fish species may shift due to warming oceans.
The UNESCO eDNA expedition spans 25 marine World Heritage sites globally, including Tubbataha Reefs, between September 2022 and April 2023. This data will contribute to the UNESCO Ocean Biodiversity Information System, the largest open-access marine species database.
The UNESCO eDNA Sampling Tubbataha Reefs
A Journey to a Marine Treasure
On April 13-14, 2023, eight volunteers aged 8 to 60 joined the Philippine local park authority’s bi-monthly visit to Tubbataha Reefs. The site, located 20 hours by boat from Palawan’s mainland, is surrounded by turquoise waters and bustling marine life.
- Sampling Process: Volunteers used specialized equipment to collect water samples from five locations within the park.
- Wildlife Encounters: Participants witnessed spinner dolphins, tiger sharks, and marine turtles inhabiting the area, enriching their understanding of marine ecosystems.
Impact on Local Communities and Science
Angelique Songco, the site’s superintendent, emphasized the importance of the eDNA initiative in introducing local staff to cutting-edge science, which will help monitor Tubbataha’s biodiversity and strengthen conservation strategies.
Why Tubbataha Reefs is a Global Marine Conservation Leader
Tubbataha Reefs Natural Park is a living testament to the Philippines’ ecological wealth:
- Marine Biodiversity: Home to over 360 coral species and almost 700 fish species, the park also shelters sharks, turtles, dolphins, and seabirds.
- Regional Importance: The reefs support fisheries beyond their boundaries, serving as a critical breeding and feeding ground.
- Diving Destination: Known for offering some of the best diving Philippines experiences, Tubbataha Reefs draws divers eager to explore its vibrant underwater landscapes.
The Role of eDNA in Conservation and Climate Research
Monitoring Biodiversity
By analyzing eDNA data, researchers gain valuable insights into the biodiversity richness of Tubbataha Reefs, enabling more effective conservation measures.
Understanding Climate Change Impacts
eDNA data combined with IPCC heat scenario projections will help predict shifts in fish species’ geographic distribution due to warming oceans, guiding future conservation planning.
Empowering Local Efforts
The inclusion of young Filipino volunteers in the project fosters awareness and engagement, ensuring that conservation knowledge is passed to future generations.
The Connection to Coron to El Nido
Tubbataha Reefs, while remote, is a critical part of the Coron to El Nido marine corridor, a route celebrated for its unparalleled beauty and ecological significance.
- Coron: Known for its WWII wreck diving and vibrant reefs, it complements Tubbataha’s pristine ecosystems.
- El Nido: Famous for its lagoons and coral gardens, it provides a gateway for divers and eco-tourists exploring Palawan’s underwater treasures.
Travelers can combine visits to Tubbataha, Coron, and El Nido to experience the best diving Philippines has to offer while supporting eco-tourism and marine conservation.
