Every Corner of the World Is a Laboratory: Dhani’s Coral Restoration Course Experience
Dhani spent years in coral farming for the export trade before one question changed his direction: how do these skills actually help protect reefs in the wild? Here’s what he learned taking Ocean Gardener’s Coral Restoration Course, from classroom to open water.
Reef Stars, Rope-and-Stake, Wire Mesh or Concrete: We’re Testing Four Coral Restoration Methods Side by Side
There’s no single “right” way to restore a reef — the best method depends on the site. We’re running a controlled, side-by-side study of four widely used coral restoration techniques at our Nusa Penida site, to find out how they actually compare on ecology, cost and long-term upkeep.
Mapping Coral Growth in 3D: What Photogrammetry Shows Us at Two of Our Restoration Sites
A photo tells you what a reef looked like for a moment. Photogrammetry tells you how it’s actually changing. Here’s how we use 3D reef mapping to monitor restoration progress, with two years of before-and-after results from our Shallow Table nursery and our Seatrees 1 outplanting site.
How Moorings Protect Marine Parks — and How to Install One That Actually Works
A boundary line on a map doesn’t stop a boat from dropping anchor on a reef. A properly installed mooring does — but only if it’s the right anchor for the seabed, sized for the right boat, and rigged so the rope never touches coral. Here’s how to get all three right.
A Buoy on the Surface, the Reef Paid the Price
One morning, a mooring line appeared out of nowhere in front of our Coral Lab in Ped — no permit, no record of who installed it, no idea what it was doing to the reef underneath. Here’s what we found when we went to look, why we had to pull it out, and what a properly installed mooring looks like instead.
From Fishers to Reef Restorers: Our First TFCCA Coral Restoration Training Batch
Under Indonesia’s new TFCCA debt-for-nature program, we ran a brand-new 3-week course built for community leaders and fishermen rather than scientists. Here’s what it took to train our first batch of seven local reef restorers in Bali, NTB and NTT — and why we think this is a model worth repeating.
Reef-Safe Diving: 10 Habits Every Diver Should Practice
Small habits underwater add up to real reef damage — or real reef protection. Here are 10 reef-safe diving habits every diver should build, from buoyancy control to the no-touch rule, from the coral restoration team at Ocean Gardener.
Is Your Sunscreen Killing the Reef? A Diver’s Guide to Reef-Safe Products
“Reef-safe” on a sunscreen label often means nothing — the term isn’t regulated. Here’s what actually damages coral, which ingredients to avoid, and how to choose sunscreen that won’t undo the reef you’re snorkeling or diving to see.
Snorkeling vs. Diving for Coral Restoration: Which Is Right for You?
You don’t need a dive certification to plant coral. Here’s how snorkeling and diving compare for hands-on coral restoration in Bali — what each lets you actually do, who it’s for, and how to go from one to the other.

April-June 2026 Updates
Q2 2026 was a period of both resilience and significant growth for Ocean Gardener in Nusa Penida. Together with the local community, we successfully outplanted over 13,000 corals and established a new Montipora nursery to bolster reef diversity following spring storm damage. Despite facing a severe marine heatwave in April, our monitoring confirms encouraging signs of recovery across our restoration sites, underscoring the vital importance of our ongoing conservation and community-led efforts.
My Experience As a Coral Restoration Intern in Bali
Coral Restoration in Nusa Penida, Bali Every restoration site has a story, and this May, I got to help write the latest chapter in Ped, Nusa Penida. For those searching for a coral restoration internship in Bali, there is no better place to gain real-world experience than with the Ocean Gardener team. I was looking for a marine conservation volunteer program that offered more than just a surface-level experience.I arrived fresh off my Conservation Divemaster in Raja Ampat, so I already had a solid foundation in reef ecology. After wrapping up the 3-Day Intro to Coral Restoration Course, I knew I wanted to dive deeper—literally—so I signed up for the Ocean Gardener Internship Program for two weeks to make a real, hands-on contribution. I was excited to be the first intern to help at their brand new Coral Lab in their main restoration site in Nusa Penida and here I will share my experience with everyone what I did. Hands-on
