Published as: Tiling the Reef--Exploring the First Step of an Ecological Engineering Tool That May Promote Phase-Shift Reversals in Coral Reefs. | Technique: Coral Gardening - Nursery Phase | Disturbance addressed: Algal phase shift | Genera: Stylophora, Pocillopora, Cyphastrea | Method: Testing the use of CD's (Compact discs) as a settlement and growing surface for coral fragments. Coral colonies were collected from the wild, from three species and ten genotypes per species, and cut into very small (similar to microfragmentation, but not called so by authors) fragments. 32 fragments attached per CD. CD's hung vertically or horizontally in mid-water nursery. | Survival of transplants reported by the source: 67.1817% | Post-restoration monitoring: 12 months | Authors' conclusion: No difference in survival of fragments between horizontal and vertical CD's for S. pistillata, and Cyphastrea, however survival differed significantly between the two positions for P.damicornis. The position affected growth in the fast growing species (S.pistillata and P. damicornis), with vertical growing more than horizontal, however this was not significant for Cyphastrea sp. Overall >80% of units survived, and fast growth was observed | 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.
