Hypothesis
Can natural colonization and coral transplantation help restore coral populations after a tsunami?
Conclusion
Coral populations in tsunami-affected areas are recovering due to natural colonization and effective coral transplantation methods.
Supporting Evidence
- High densities of baby corals were found in 60 locations.
- Natural colonization by resilient coral species is aiding recovery.
- Transplanting baby corals is more effective than direct seeding.
Takeaway
After a big wave destroyed many corals, new baby corals are growing back because stronger types are moving in and people are helping by planting them.
Methodology
Survey of coral populations in tsunami-affected locations.
