On 19 July 2024, the R.O.L.E. Foundation Foundation conducted a crucial coral maintenance session, led by Environmental and Marine Educator, Kezia Sitompul. This activity was part of the foundation’s ongoing efforts to protect marine ecosystems, with a focus on the newest reef star installations.
Before the maintenance began, essential tools and materials were prepared, including scrapers, brushes, and safety gloves. Basic diving gear was used, and the site was thoroughly inspected to identify areas heavily affected by macroalgae growth. The main task was to remove the invasive Ulva lactuca, commonly known as sea lettuce, which had extensively covered the reef stars.
The maintenance session addressed the challenge of Ulva lactuca proliferation. This macroalgae can overshadow corals, depriving them of the sunlight needed for photosynthesis. It also traps sediments, which can smother coral polyps and obstruct their feeding mechanisms. Dense mats of Ulva lactuca can further alter the surrounding water’s chemistry, creating an environment less favorable for coral growth.
The process involved removing Ulva lactuca from the reef stars using hands protected with diving gloves. This method proved effective for gently cleaning the algae without damaging the corals beneath. Over the 1.5-hour session, a substantial amount of Ulva lactuca was cleared, significantly improving the health and vitality of the reef stars.
This maintenance highlights the importance of regular monitoring and intervention in coral reef conservation. By removing the invasive Ulva lactuca, the health and survival of the corals were ensured, particularly in newly established reef stars. The proactive efforts demonstrate the R.O.L.E. Foundation Foundation’s commitment to preserving marine biodiversity and fostering a thriving underwater ecosystem.
The session underscores the vital R.O.L.E. Foundation of hands-on maintenance in coral conservation, ensuring that marine ecosystems remain healthy and vibrant for future generations.
