Published as: Large coral transplantation in Bal Haf (Yemen): an opportunity to save corals during the construction of a Liquefied Natural Gas plant using innovative techniques | Technique: Transplantation | Disturbance addressed: Construction | Genera: Acropora, Porites, Platygyra, Stylophora, Favites, Montipora, Pavona | Method: 1,500 coral colonies belonging to 36 species and 25 genera were removed from areas to be impacted, transported and cemented in new sites. 140 large Porites spp. weighing from 200 kg up to 4 tonnes, were moved using new transplantation techniques. Growth, in situ mortality and health of the transplants were monitored over one year using photo quadrats, close-up pictures and linear growth measurements. | Survival of transplants reported by the source: 89% | Post-restoration monitoring: 14 months | Authors' conclusion: Overall, survival of corals one year after transplantation was 91%. Most losses of transplants were due to sedimentation, fish predation, fisher activity and swell effects. Evidence of coral growth after transplantation was observed, especially in Acropora and Porites species, and on some faviids. | Lessons reported: The use of a screws drilled directly into the coral skeleton to fix to lifting balloons was an innovative technique to transport large corals. | 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.
