Sowing life beneath the waves: Galapagos coral restoration

Around the world, climate change, ocean acidification, pollution, and destructive fishing practices have caused deep and lasting damage. In the Galapagos, in 1982, high water temperatures caused by El Niño wiped out 97% of the coral cover. In the face of this mass loss, coral reef restoration has become a critical and strategic action for the future of our oceans.

In response, the Galápagos Reef Revival Project was launched in 2021. It is part of the coral reef restoration program led by the Galápagos National Park Directorate, in collaboration with scientific and conservation institutions, such as Jocotoco.

The "coral gardening" technique used involves collecting coral fragments and growing them in underwater nurseries for 9 to 12 months until they reach a suitable size. These corals are then transplanted onto degraded reefs. During this time, the fragments receive specialized care, including weekly cleaning to prevent disease and continuous growth monitoring. What sets Galapagos Reef Revival apart is its focus on coral genetics, selecting specimens that have survived extreme events such as the 1982 El Niño. This approach allows for the restoration of ecosystems with corals that are the most resilient to climate change.

In just a few years, the results are remarkable: approximately 8,000 m² of reef ecosystem has been re established with more than 6,700 corals of 50 different coral varieties, which showcase nearly 100% survivorship. This has transformed "La Calera" historic Reef in Isabela Island, the most extensive coral ecosystem in the main islands of the Galapagos.

The project has also contributed valuable scientific knowledge. Its achievements include the first in-depth study of coral growth and survival in the Galápagos Islands, a framework for coral cultivation on Isabela Island, the first assessment of coral restoration impact on fish diversity and abundance, and the development of a comprehensive coral management plan for the region.

One of the most important findings of the project is how temperature fluctuations affect coral development. Not only does extreme heat cause stress, but cold water during La Niña events also has a significant impact, reducing coral growth and survival. These findings position Galapagos as an important natural laboratory for shaping global reef restoration strategies.

The long-term sustainability of these efforts depends largely on the involvement of the local community. Through educational programs and hands-on workshops, children, teens, and adults learn about the importance of coral reefs. Fishers, tour guides, and local residents actively participate in monitoring and restoration efforts, building a strong sense of ownership and environmental responsibility. 

Soon, we hope to expand these efforts to include coral restoration around other islands, such as Floreana, San Cristóbal, and Española. Now more than ever, a collective commitment is needed to protect these precious ecosystems. You can make restoration, research, and education possibleensuring that coral reefs remain a source of life. Your donation has the power to protect our oceans and leave a legacy of hope for the planet.

Galápagos Reef Revival is a collaborative project made possible by the support of dedicated scientific and conservation institutions: Galápagos National Park, Re:Wild, Universidad San Francisco de Quito, Galápagos Science Center, The Rufford Foundation, and Fundación Jocotoco.
