Transplantation — Bolinao

Published as: Employing a highly fragmented, weedy coral species in reef restoration | Technique: Transplantation | Disturbance addressed: Destructive fishing | Genera: Montipora | Method: Almost 2000 coral ramets were reared in a shallow lagoon nursery for 1 year and then transplanted onto denuded reef knolls at two different sites and according to three transplantation designs (grid design with high or low density and patch design). | Survival of transplants reported by the source: 17% | Post-restoration monitoring: 15 months | Authors' conclusion: M. digitata ramets in the nursery exhibited 87% survivorship and fast growth rates (217–927%) in 1 year. Following transplantation, 17% of the corals remained alive with 37% loss due to mortality and 46% loss due to detachment. Growth increased the corals’ ecological volume by 384%. The high number of M. digitata survivors enhanced local habitat complexity. | Lessons reported: The weakness in the transplantation phase was M. digitata’s slow attachment to the substrate, which may be improved by having the coral tissue touching the substrate by drilling deeper holes in it. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work. No contribution to the condition index is recorded: the source reports survival of transplanted material, which is not a measure of ecosystem condition.

Recorded result

No result recorded yet. A result is recorded when the project moves to Paused, Completed or Discontinued.

A variable shows "pending" instead of a contribution when no domain area has been set for it yet — the share of the world a project touched cannot be computed without one. The health percentages are accurate regardless.
