OCEAN ENCOUNTERS
Coral Planting Programs Ranked
Real science vs. marketing. Which programs track their frames for years and which hand you a certificate and forget.
How We Rate Programs
Four criteria, equally weighted. A programme must score well on all four to earn a "Genuine Science" rating.
Scientific Methodology
25%Is coral species selection based on reef assessments? Are donor colonies chosen for genetic diversity? Is frame placement guided by current, light, and depth analysis?
Monitoring Commitment
25%Are frames tracked for 1+ years? Is growth data recorded? Are survival rates published? Can guests see updates?
Guest Participation Depth
25%Does the experience include education? Is the process supervised by a marine biologist? Do guests understand why they are doing each step?
Marine Biologist Involvement
25%Is a trained marine biologist (not just a dive instructor) involved in the programme design and execution?
Program-by-Program Assessment
From best to worst. We are not affiliated with any resort; this rating is based on published data, marine biologist interviews, and guest reports.
Four Seasons Reefscapers
Four Seasons Landaa Giraavaru / Kuda Huraa
Guest participation
Guests help attach coral fragments to metal frames. Marine biologists select donor colonies and supervise placement. Each frame is GPS-tagged.
Monitoring and data
Long-term tracking with online portal. Guests can check their frame's growth years later.
Years Running
10+ years
Frames Deployed
300+ coral frames
Marine Biologist
Full-time marine biologist team

Red Flags to Watch For
How to tell if a coral programme is marketing, not science.
No marine biologist present
If a water sports instructor leads the session, the coral selection is likely random. Species choice matters for survival.
Session under 30 minutes
If the entire process takes 15 minutes, there is no time for education or proper technique. It is a photo stop.
No follow-up or tracking system
If you cannot check on your frame's progress later, the resort likely does not monitor it either.
Certificate but no GPS tag
A certificate with your name is easy to print. A GPS-tagged frame with a tracking number means the resort actually monitors the reef.
No published survival data
Coral frame survival rates vary from 20% to 80%. If a programme never shares this number, the results may not be good.
"100% success" claims
No coral programme has 100% frame survival. Bleaching, storms, and predation kill some frames. Honest programmes publish real numbers.
What Happens After You Leave
The real test of any coral programme is what happens in the years after your visit.
At genuine programmes
Marine biologists dive to your frame regularly. They photograph it, measure growth, remove algae competitors, and record which fragments survived. Some programmes let you view your frame's progress through an online portal. Four Seasons Reefscapers sends annual photo updates.
At photo-op programmes
The frame stays where you placed it. Nobody monitors it. If it gets damaged by a storm or covered in algae, nobody intervenes. Some frames end up buried in sand or moved by currents. There is no way to know what happened to your coral.
The honest truth
Even at the best programmes, not every fragment survives. Bleaching events (2016 was severe in the Maldives) can kill large percentages of planted coral. The value of genuine programmes is that they track these losses and adjust their methods.
Practical Information
Snorkel or Dive?
- Most programmes are snorkel-based
- Coral frames sit at 3 to 8 meters depth
- Four Seasons offers both snorkel and dive options
- No certification needed for snorkel sessions
- Stronger swimmers can freedive to frames
Family Suitability
- Children 8+ at most programmes
- Four Seasons accepts families with 10+
- Good educational activity for older children
- Sessions are gentle (no strong currents)
- Photo certificate appeals to younger participants
When to Book
- Available year-round at all programmes
- Book within first 2 days of your stay
- Morning sessions avoid afternoon heat
- Calm seas (dry season) make access easier
- No advance booking needed; book at resort
