Measures being investigated to help the Reef resist, adapt and recover

Cooling and shading

Aimed at preventing coral stress by cooling and shading reef waters, this type of intervention includes reducing the amount of heat and light reaching reef water through cloud brightening, fogging and applying biodegrable surface films.

 

Reef structures and stabilisation

Methods such as stabilising loose coral rubble and creating artificial reef surfaces and structures aim to speed reef recovery following a disturbance - such as a cyclone, ship grounding or fatal coral bleaching - by supporting coral recruitment and regrowth. 

Coral reproduction and recruitment

This type of method includes reseeding reefs with coral larvae collected from natural spawning slicks, as well as coral cultured through aquaculture, to enhance coral reproduction and reef recovery following disturbance.

Biocontrol

Managing coral predators and competitors to facilitate reef recovery or maintain reef health.

 

Field treatments

Increasing coral survival and health following disturbance with probiotics, feeding, medicines or other treatments.

Seeding enhanced corals from existing stock

Aimed at enhancing temperature tolerance, and other desirable traits to facilitate natural populations' adaptation to environmental change, this method includes seeding reefs with corals from existing stock that have enhanced performance, to increase coral health and tolerance.

Seeding enhanced corals bred from engineered stock

Seeding reefs with corals that have enhanced performance derived from synthetic biology and gene editing approaches, to increase reef health and tolerance.

Current practices

RRAP Concept Feasibility Study report T4 - Current Practices provides a summary of the current global knowledge of coral restoration methods and practices to date, and highlights common issues encountered as the field has evolved. Use our visualisation tool to explore current restoration methods.
