Published as: Assessment of juvenile coral populations at two reef restoration sites in the Florida Keys National Marine Sanctuary: Indicators of success? | Technique: Substrate Addition - Artificial reef | Disturbance addressed: Ship grounding | Genera: Porites, Diploria, Favia, Siderastrea, Agaricia, Millepora, Pseudopterogorgia, Montastrea | Method: Three years after restoration of 2 ship grounding sites, coral and benthic (which were at most 3 yrs old) were mapped and identified. The two sites, characterised by different materials, were compared. | Authors' conclusion: Coral assemblages differ markedly in density, size distribution, and diversity between the two sites. Within the Maitland site, coral recruitment is positively associated with rough lime rocks embedded in the concrete restoration structure, but the coral assemblage is dominated by a single species, Porites astreoides. At the Elpis site, the juvenile coral assemblage has four taxa and juvenile coral density 50% greater than Maitland. This is probably due to differences in the benthic algal assemblages at the two sites, resulting from differing structure designs (e.g., differing material, surfa… | Lessons reported: Horizontal surfaces are likely to enhance sediment trapping by filamentous algae. Surface roughness is likely to be correlated with a more diverse coral assemblage. Surfaces that promote the growth of CCA are also likely to attract a more diverse coral community. | 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.
