Published as: Initial survival of coral nubbins transplanted by a new coral transplantation technology - Options for reef rehabilitation. | Technique: Substrate Enhancement - Electric | Genera: Stylophora, Pocillopora, Acropora, Montipora, Pavona | Method: A folded steel (chicken wire) cathode was connected to a DC power supply, and an anode of titanium mesh, placed 20 cm above each square. The magnesium and calcium minerals precipitate on the cathode by electrochemical deposition, and can form a calcium carbonate layer of 5-10mm thickness within 2 months. Coral fragments are inserted into the mesh (cathode) | Survival of transplants reported by the source: 67.5% | Post-restoration monitoring: 12 months | Authors' conclusion: After 8 weeks, fragments were cemented to the mesh. After 12 months, a large proportion were still alive, and had continued to grow. | 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.
