Coral Gardening — Lazarus Island

Published as: A cost-effective approach to enhance scleractinian diversity on artificial shorelines. | Technique: Coral Gardening | Genera: Podabacia, Merulina, Echinopora, Hydnophora, Pocillopora, Platygyra | Method: Coral colonies collected and fragmented from nearby site. Placed on table nurseries for up to 9 months. Fragments were then transplanted onto granite seawall. | Survival of transplants reported by the source: 89.7% | Post-restoration monitoring: 6 months | Authors' conclusion: High survival in both nurseries (98.5%) and transplants (89.7%). All fragments increased in growth, except for M. ampliata species. Coral cover on the site increased from 3% to 20.5% in 6 months. | Lessons reported: Nursery was located in a high sediment environment, and high survival of these species indicates they are robust to high sediment loads during propagation. Drupella snails were disproportionately attacking P. damicornis transplants. (Note: Photos show cable ties digging in to fragments in nurseries. Account for growth in attachment methods, so as not to limit fragment growth.) | 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.
