Substrate stabilisation and small structures in coral restoration: State of knowledge, and considerations for management and implementation

Stages in the stabilisation and binding of rubble.
Stages of the natural stabilisation of rubble fields and eventual conversion to reef framework. A) shelter from strong hydrodynamic activities, a depression in bathymetry or particle organisation into stable bedforms allows the rubble pieces to settle, interlock and stabilise; b) pioneer binding organisms such as fleshy and calcareous algae settle on the rubble; c) intermediate binders such as cryptic and erect sponges create greater stability; and d) late stage binders and coral settlement.
