Published as: Coral relocation for impact mitigation in Northern Qatar. | Technique: Transplantation | Disturbance addressed: Construction | Genera: Anomastraea, Cyphastrea, Favia, Platygyra, Plesiastrea, Porites, Pseudosiderastrea | Method: Over 4,500 hard corals were relocated from pipeline corridors to mitigate for pipeline installation impacts. Proven techniques for coral reattachment and newly developed methods to enhance coral survival were used for the mass recovery, transport, and reattachment of the corals. 6 of the 22 reattachment sites were randomly selected for bi-annual monitoring. A subset of the relocated corals (approximately 5%) and natural (reference) corals were randomly selected to monitor the relative coral hea… | Survival of transplants reported by the source: 99% | Post-restoration monitoring: 12 months | Authors' conclusion: After one year, 99% of the reattached monitored colonies survived compared to 79% survival of reference colonies, and a greater percentage of reattached colonies were healthy (58%) when compared to reference colonies (33%). Hard corals and other fauna (e.g., sponges and oysters) combined provided less than 12% cover during the surveys, and the benthic community was instead dominated by algae. | Lessons reported: Hard coral relocation is a viable means of off-site mitigation for unavoidable impacts to sensitive coral habitats. | 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.
