Depending on their size, barrier reefs and atolls can take from 100,000 to 30,000,000 years to fully form. As coral reefs grow, they establish characteristic biogeographic patterns.

Coral restoration means moving nursery-reared corals to restoration sites. After six to eight months growing in the nursery, corals are healthy and mature enough to be transplanted to a restoration site. These are reef sites that are degraded and damaged and would benefit from Staghorn and Elkhorn corals growing there. Corals are taken from the nursery and are transplanted to restoration sites (damaged reef areas) using a couple of different methods.
