Published as: Coral translocation and farming as mitigation and conservation measures for coastal development in the Red Sea: Aqaba case study, Jordan. | Technique: Transplantation | Disturbance addressed: Construction | Genera: Platygyra, Favia, Favites, Hydnophora, Montipora, Porites, Acropora, Pocillopora, Stylophora, Nephthya, Turbinaria, Millepora, Astreopora, Galaxea, Lobophyllia, Tubastrea, Leptoria, Goniastrea, Monta… | Method: 7000 coral colonies threatened by port development were moved and transplanted into degraded reef sites in Aqaba Marine Park. Survival and growth rates were monitored biannually for 2 years and compared to growth rates at a control site. | Survival of transplants reported by the source: 87.3% | Post-restoration monitoring: 24 months | Authors' conclusion: The overall survival rate for the transplanted colonies was similar to colonies of the same species at the control site. Three species demonstrated more than 1 cm of linear growth per year. The overall survival rate of nubbins in a nearby nursery was 88 %, and the annual linear growth rate ranged from 0.32 cm to 0.99 cm. High survival and linear growth rates indicate that the transplantation site selection and the techniques employed were successful. | Lessons reported: Choosing a receptor site similar to the donor site, transporting the colonies underwater, taking care to minimize physical contact with the coral tissue during all transplantation processes, and only choosing healthy colonies for translocation led to a successful translocation and transplantation project. | 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.
