What Ocean Gardener does
Ocean Gardener (legal entity Yayasan Samudera Kebun Coral) is a Bali-based non-profit founded formally in 2018, with restoration operations dating to 2016, dedicated to coral reef restoration and education across Indonesia. It runs a distributed network of 13 coral nurseries and restoration sites spanning Amed/Lipah Bay, Ped (Nusa Penida), Tulamben, Candidasa, Sanur, Pemuteran, Gamat Bay (Nusa Ceningan), Bangka, Raja Ampat, Ambon, Bira (South Sulawesi), and Banda Neira, in partnership with resorts, dive shops, NGOs, and local fishing communities. Its core technology comprises coral gardening and asexual fragmentation techniques using rope-and-stake, Reef Stars, cement attachment, Mineral Accretion Technology (MAT), and wire mesh rubble stabilization, supported by a copyright on coral propagation techniques held by co-founder Manumudhita. A real-time cloud tracking platform for coral plantings, pest events, and spawning monitoring was launched as a pilot in July 2025.
The organization serves four primary customer segments: (1) eco-tourists who book snorkel restoration experiences in Amed (1.4M IDR) and Nusa Penida; (2) certified scuba divers taking professional courses ranging from a 3-day Intro to Coral Restoration (5.7M IDR) to a 4-week Full Coral Restoration Certificate (14.3M IDR) to a 10-day Acropora ID specialty (26.8M IDR); (3) Indonesian coastal communities trained via a TFCCA-funded program delivered in Bahasa Indonesia; and (4) donors and corporate sponsors supporting through one-time or monthly donations and the Canopi-hosted Coral Adoption program. Revenue streams include course fees, eco-tourism, internship fees (800K IDR/day to 13M IDR/month), coral adoptions, donations, and grants from foundations including McPike-Zima, MERO, and TFCCA. The core team of 8 marine biologists, divers, and administrators is led by founder Vincent Chalias (25 years of coral farming experience) and co-founders Nicole Helgason and Manumudhita. Cumulative impact includes 345,721 corals planted and tracked, 636 people trained, 34 scholarships awarded, and a documented recovery from <5% to 52% hard coral cover over 1.2 km of reef at the Ped restoration site.

Ocean Gardener competitors and assessment
Company assessmentOthers
- Sea Shepherd Conservation Society: Sea Shepherd is a global marine conservation NGO with a large donor base and brand presence in ocean advocacy. It does not perform coral restoration but competes for the same philanthropic and corporate-sponsor attention that funds Ocean Gardener.
Broad incumbents
- Coral Reef Alliance: CORAL is a long-established global reef conservation NGO working on protection, policy, and community-based reef management. While Ocean Gardener is hands-on restoration, both share donor pools, marine conservation framing, and reef ecosystem missions.
- Reef-World Foundation: Reef-World runs the Green Fins environmental standards for dive and snorkel operators globally. It connects to Ocean Gardener through the dive tourism infrastructure (Ceningan Divers is Green Fins-certified) and shared donor base for reef-friendly tourism.
- Mars Coral Reef Restoration Program: Mars operates a large-scale coral restoration program across multiple geographies with substantial corporate R&D backing. It overlaps on coral propagation science and reef restoration methodology but operates at much larger scope and budget than Ocean Gardener.
Direct peers
- New Heaven Reef Conservation Program: New Heaven runs a small-scale coral nursery, reef restoration, and dive training program in Thailand with strong educational and community components. Its combination of citizen-science, internships, and reef monitoring closely mirrors Ocean Gardener's training-led approach.
- Sulubaaï Environmental Foundation: Sulubaaï runs a coral reef restoration project in the Philippines using coral nurseries and community engagement. Its methodology, target audience (Southeast Asian coastal communities), and educational emphasis make it a direct regional peer.
- Coral Vita: Coral Vita runs commercial-scale coral farming and reef restoration in the Bahamas using similar assisted-evolution and nursery techniques. Both organizations operate coral nurseries, conduct outplanting, sell educational experiences, and pursue reef restoration as their core mission.
- Reefscapers: Reefscapers (Four Seasons Maldives) restores reefs using low-tech coral propagation frames and offers guest participation in coral planting — a direct parallel to Ocean Gardener's snorkel experiences and resort-hosted nursery model across Indonesia.
- Reef Renewal Foundation Bonaire: Reef Renewal Foundation operates coral nurseries and outplanting programs in Bonaire using similar coral gardening and fragmentation methods. It runs citizen-science and dive-volunteer experiences comparable to Ocean Gardener's eco-tourism and training programs.
Regional players
- Coral Triangle Center: Coral Triangle Center works across Indonesia and the broader Coral Triangle on marine protected area management, training, and reef conservation. It overlaps Ocean Gardener on Indonesian reef training but focuses on policy and MPA management rather than direct restoration.
