Coral Nurseries

Coral restoration at scale is like a system of agriculture: collect, regrow, propagate, repeat.

At Coralku, coral nurseries are used in three ways: to regrow broken coral fragments, to establish 'breeding banks' with coral species that have severely declined in abundance, and to conduct essential scientific assessments and experiments.

Each method, however, serves the same purpose: to supply degraded reef sites with new corals. Every year after the monsoon season, we plant all of the successful corals from our nurseries back into designated restoration areas, and monitor their development and wellbeing. We use two main nursery types: coral trees and floating rebar platforms. Nurseries are kept above the seabed to shelter corals from moving sediments and predators. We predominantly collect broken coral fragments, found loose on the seabed, to stock our nurseries, and we make sure that our collection protocols maximize genetic diversity in our nurseries. During this process from loose fragment to coral outplant, everything is being recorded and evaluated. We strive with scientific documentation!
