Published as: Effects of coral transplantation in sites of varying distances and environmental conditions | Technique: Transplantation | Genera: Acropora, Porites, Echinopora | Method: Whole colonies pried off using hammer and chisel. Sizes ranged up to three-fold for all species. Transferred to transplant site. Two attachment methods tested: 1) depression excavated in rock, cement mix with seawater poured in depression covering the base of the coral, 2) tied to plastic screen (1m²) nailed to surface. Each attachment equals a treatment and each was replicated three times, hence 6 plots (each 1m², with 7 or 12 colonies in each plot) per transplant site and 4 sites per location… | Survival of transplants reported by the source: 57.125% | Authors' conclusion: Survivorship higher for slow-growing corals, than branching and foliose. Highest survival for A.palifera (94%) and lowest for A.microphthalma (8%); clear trend in higher survivorship in Quezon sites (62-95%) than Pangasian sites (39-16%). Growth differed between most species across all sites, highest growth rate compared to low survivorship for A. microphthalma and E. lamellosa. No growth difference between attachment method, but survival higher in cement method. Hence successful coral transplantation is both site- and species-specific. | Lessons reported: Growth and survival rates, however, should not be considered as the sole criteria in the evaluation of transplantation performance, as reproduction strategy should be taken into account. Consider broad environmental context of restoration to develop assembly rules allowing to match coral types and their sequence to each unique context. | 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.
