What are rock piles used for in coral restoration?

Rock piles play a vital role in coral restoration by stabilizing and consolidating rubble on the seafloor. This process is crucial because when corals are damaged, their substrate can become unstable, leading to further erosion and sedimentation that impede recovery efforts. By creating rock piles, restoration practitioners provide a stable base that allows coral larvae to settle and grow, facilitating natural recruitment and ultimately supporting the overall health of the coral ecosystem.

The consolidation of rubble also serves to protect the area from strong currents and wave action, reducing physical disturbance to the fragile coral fragments and newly established colonies. This stabilization is essential in creating a favorable environment for coral growth and ensuring that restoration efforts are successful over the long term.
