Published as: Low-Tech Rehabilitation of Degraded Coral Reefs through Transplantation of Staghorn Corals | Technique: Transplantation | Disturbance addressed: General degradation | Genera: Acropora | Method: Staghorn corals were transplanted to investigate the effects of the following three factors: i) Attachment: Unattached corals were compared to corals tied together on strings. ii) Density: Corals were placed either densely with a cover of 30-40% or sparsely with a cover of 10-15%. iii) Site: The corals were transplanted to two sites (E and P) with different substrate and exposure to waves. The corals were transplanted to 32 plots in a fully orthogonal design, with 8 combinations of levels (two … | Post-restoration monitoring: 23 months | Authors' conclusion: After 23 months, the cover of the transplanted corals had increased by 51%, and other benthic species recruited. Coral cover increased more in the sparse treatment (per unit of transplanted coral), probably due to the lesser degree of competition between adjacent colonies | Lessons reported: The method of tying corals together with strings before placement on the seabed was effective and could be applied for rehabilitation of degraded coral reefs that are moderately exposed to water movements. | 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.
