Published as: Kāne‘ohe Bay Reef Restoration Project | Technique: Substrate Enhancement - Algae removal | Disturbance addressed: Invasive algae | Method: Removal of invasive algae from reef with divers and suction device. Introduction of grazing urchins. | Post-restoration monitoring: 36 months | Authors' conclusion: 17 acres of algae were cleared and kept clear with urchins. 100% removal with dental tools was also trialled, with positive outcomes | Lessons reported: Effective clearing of macroalgae with mechanical suction device. Algal clearing must be paired with enhanced herbivory to be effective. | 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.

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.
