Published as: Best practices manual for Caribbean Acropora restoration. Puntacana Ecological Foundation. | Technique: Coral Gardening - Nursery Phase | Genera: not relevant | Method: Building hurricane resistant coral nursery tables. Tables suspend fragments ~1m above substratum to avoid smothering by sand. Built with 16mm thick metal bars, and placed in direction with the prevailing currents.Bars are joined using UV-resistant cable ties.Ropes are tied to end legs, and coral fragments attached as 'mother colonies'. | Authors' conclusion: Tables avoid problems with predators, suspended sediment and silt. Tables can support heavy weight and can therefore be used to support mother colonies. If installed correctly they can be hurricane resistant. Mother colonies grow fast on rope nursery and may only need to be trimmed once a year. | Lessons reported: Poor quality cable ties can disintegrate, tables are vulnerable to snagging on anchors. Avoid electrolysis by avoiding different metals in contact with each other (ie use plastic coated wire/trays on top of metal bars). If placed near reefs, the tables are virtually maintenance free as resident fish clean off any fouling organisms and potential predators. The rope method is primarily for the prod… | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work.

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.
