Transplantation — Apra Harbor

Published as: Preservation of rare coral species by transplantation and examination of their recruitment and growth | Technique: Transplantation | Disturbance addressed: General degradation | Genera: Pavona, Montipora, Leptoseris | Method: Three rare coral species were transplanted from a degraded harbor into areas unaffected by pollution. Each new habitat had three sites located at three depths (1.5 m, 4m, and 10m). Three transplant methods were used, fully grown coral heads of different sizes, broken shards, or branches scattered in large numbers, and coral nubbins attached to terracotta bricks. Growth and survival were recorded over a 12 month period. | Survival of transplants reported by the source: 32.2411% | Post-restoration monitoring: 12 months | Authors' conclusion: Survival rates were highly variable. The deepest sites had the least mortality for both habitats. Survival at the shallowest sites, which had the greatest mortality, was affected by wave action and light intensity. | Lessons reported: Transplanting heads, regardless of size, was a better method than transplanting nubbins or shards. | 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.
