The area boasts a healthy foundational ecosystem
On March 8–9, 2026, marine experts headed into the blue to explore and document the incredible biodiversity of the Merlin Beach reef.
Using the specialized "Photo Belt Transect" method, the team recorded vital baseline data on the marine ecosystem. This research is a crucial step in proposing the shoreline as a Locally Managed Marine Area (LMMA)—a protected ecological sanctuary managed by the community, for the community.
A Thriving, Healthy Reef The survey revealed fantastic news beneath the waves: the reef is in great shape, officially assessed as being in "moderate to good" condition and is buzzing with a rich variety of marine life:
• Corals: The area boasts a healthy foundational ecosystem, dominated by Hump coral (Porites sp.). Other significant species supporting the reef include Staghorn coral (Acropora sp.), Pore coral (Montipora sp.) and Lobbed brain coral (Lobophyllia sp.).
• Fish: A wide variety of fish were observed, most notably Parrotfish (Scaridae), which play a vital role in maintaining reef health by controlling algae growth. Dominant species include the Swarthy Parrotfish (Scarus niger), Quoy’s Parrotfish (Scarus quoyi) and Singapore Parrotfish (Scarus prasiognathos). The reef is also home to Butterflyfish, Wrasses and Groupers.
• Invertebrates: The seabed is kept healthy by a diverse range of invertebrates, led by Sea Cucumbers (Holothuroidea), which are crucial for decomposing organic matter and natural nutrient cycling. The Lolly Sea Cucumber (Holothuria atra) and Black Sea Cucumber (Holothuria leucospilota) are highly prevalent, actively turning over sediment to maintain a balanced benthic ecosystem. Divers also recorded sightings of Giant clams and colorful Sea slugs (Nudibranchs).
A Long-Term Commitment to the Planet This assessment is not just a one-time visit. The WildAid Thailand team and the resort will continue to monitor the biodiversity and health of the reef every quarter.
By protecting the vibrant waters of Merlin Beach and pushing to establish an LMMA, Phuket Marriott Resort & Spa, Merlin Beach and WildAid Thailand are actively contributing to the global “30x30” mission—the vital international environmental goal to protect and conserve at least 30% of our planet’s land and ocean by the year 2030.
