Coral Gardening — Changi

Published as: Enhancing the biodiversity of coastal defence structures: transplantation of nursery-reared reef biota onto intertidal seawalls | Technique: Coral Gardening | Disturbance addressed: Construction | Genera: Porites, Pocillopora, Diploastrea, Goniastrea | Method: The project is attempting to establish a coral reef on sewalls erected in area of high ship traffic. Fragments collected and transported to ex situ nursery, stored for 1 month, then further fragmented, and allowed to grow in holding tanks for a further 3 months. Coral fragments were then attached (15 cm apart) to the stone seawall using marine epoxy. | Survival of transplants reported by the source: 15.9% | Post-restoration monitoring: 24 months | Authors' conclusion: Almost half of P. lobata fragments survived after 2 years, however P. damicornis and H rigida suffered complete mortality after 2 months. 90% G. minuta and 10% D. heliopora survived after 12 months. | Lessons reported: While all coral species were present on nearby reefs, some were more successful than others. Slow growing massive corals were better suited for the high energy environment than fast-growing branching corals, which were more vulnerable to becoming dislodged by flotsam. | 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.
