Bali quiet revolution is underway beneath the quiet blue waters of the island. The next chapter of ocean restoration is no longer a dream at R.O.L.E. Foundation’s Coral Garden—it’s coming true. Our reefstar structures, anything from empty steel frames, are now experiencing the unbelievable: wild coral are naturally settling on them and growing healthily. This is a significant project milestone, and it is also an emblem of hope for our oceans, as well as evidence that with the right efforts, nature can ultimately heal itself.
The Ocean’s Silent Comeback
Coral reefs are the lungs of the ocean, giving shelter, food and oxygen to so many marine species. But Bali’s reefs have been damaged over the past few years by climate change, destructive fishing and pollution. We choose to turn challenges into opportunities at R.O.L.E. Foundation. That’s why we’ve started the Coral Restoration Program to restore damaged reefs and ensure the health of our ocean’s marine life for generations to come.
What is a Reefstar and Why Does it Matter?
Reefstars are six-sided steel shapes in a hex pattern that are coated in a marine-safe finish, and are used as artificial reef structure substrates. They’re tough, long-lasting and mimic the real-life sprawl of coral reef that marine life thrives upon. Now we’ve had these Reefstar installed into our Coral Garden for a while, and we’ve been keeping a close eye on them. At first, we spackled coral fragments to nudge things along — but the actual magic is when wild corals come on their own.
Nature Takes Over: Wild Coral Growth on Reefstars

Recently, during a routine coral maintenance at our Coral Garden, our team observed something truly remarkable: wild coral polyps had begun to settle and grow on the Reefstar frames without any human assistance. This spontaneous colonization is a crucial milestone. It means our restoration site is enough to attract marine life and foster natural recovery. Why is this important? Because natural recruitment shows that the ecosystem is regenerating on its own. It’s a positive feedback loop: the more coral grows, the more fish come; the more fish come, the healthier the ecosystem becomes.
A Ripple Effect for the Future
This progress goes beyond biology—it represents hope for coastal communities, sustainable tourism, and the fight against climate change. Healthy reefs provide food security, protect shorelines, and support livelihoods. Every Reefstar that turns into a thriving coral garden brings us one step closer to a resilient ocean.
Together, we can turn the tide for our oceans. Because when nature gets a helping hand, it answers with life.
