Published as: Three methods of coral transplantation for the purpose of reestablishing a coral community in the thermal effluent area at the Tanguisson power plant. University of Guam, Marine Laboratory. | Technique: Transplantation | Disturbance addressed: Thermal effluent | Genera: Psammocora, Stylophora, Pocillopora, Acropora, Montipora, Pavona, Porites, Favia, Lobophyllia | Method: An early transplantation experiment testing whether corals which have a higher thermal tolerance can be transplanted onto a site impacted by thermal effluent from a power plant. Three transplantation techniques were tested: 1) Whole colonies were removed and attached at the site using plastic coated wire. 2) Fragments were scattered over the reef area, 3) Coral nubbins were epoxied onto terracotta tiles and placed on the restoration site. The transplantation site was divided by distance to heat… | Survival of transplants reported by the source: 0% | Post-restoration monitoring: 14 months | Authors' conclusion: All corals transplanted into thermal effluent zone died, and the authors conclude that it is not possible to transplant corals species known to show thermal tolerance into a reef area subjected to high temperatures. All fragments scattered on the reef were lost after 2 months. Similarly, all terracotta tiles with nubbins were also lost. High survival of transplanted corals in control areas however (89 and 95%). | Lessons reported: Even though species may be thermally tolerant, they may be stressed due to to other factors (eg. irradiance). Colonies on control reefs (without thermal effluent) rapidly overgrow the plastic covered wire, and show hgh survival. | 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.
