Coral Restoration Theory & Techniques
Recent studies have found that about 50% of the world’s coral reefs have already been lost, and the other 50% are highly threatened. The long running philosophy of “protection is always preferred over restoration” is a luxury which no longer applies to most regions. More and more, restoration is necessary to preserve the biodiversity and functionality of reefs, and to ensure the sustainability of the resources they provide.
Our reef restoration programs have evolved greatly since our first coral nursery in 2007. We take an ecosystem approach to restoration, which means that we take a holistic approach, focusing on the long-term sustainability and adaptability of the ecosystem rather then just trying to add more corals into areas where they will not survive. This approach has proven successful, as detailed in this 2020 independent analysis of our reef restoration techniques following more than 10 years of our concentrated efforts.
Our courses are on the cutting-edge of science-based coral restoration with a focus on genetics, adaptability, and resilience. We also adhere to the code of ethics as outlined by the Coral Restoration Consortium. Participants in our program will learn all of the theory and techniques behind coral reef restoration, as well as get hands on practice in these techniques. With almost 15 years of experience, we can ensure that everybody coming through our program will leave feeling knowledgeable enough to initiate programs of their own, and confident enough in their skills to carry those projects out to completion.
