Student Testimonials​

“Ocean Gardener's course activated a deep passion for coral in me - ever since taking their course in 2018 I have been involved in various coral nursery and restoration projects. Both the beginner and advanced courses have been some of the most enjoyable and rewarding experiences I've had.”
Andrew Batunai, USA
The Coral Reef Conservation and Restoration course exceeded all my expectations. From day one, I was enthralled by the wealth of knowledge presented by the instructor. Their passion for coral reef conservation was infectious, making each topic come alive. Throughout the course, I delved into Coral ID, anemones, sea fans, and the distinctions between soft and hard corals. I also learned various restoration techniques and monitoring methods. The course was thoughtfully structured, allowing ample time for practice and clarifications. I am grateful for the opportunity to apply what I learned in my future endeavors. I plan to continue exploring and assessing coral reefs while assisting Ocean Gardener with maintenance and future courses. I wholeheartedly recommend this course to anyone interested in coral reef conservation. The expertise and instruction provided are unparalleled. Thank you for an unforgettable experience!

“The Ocean Gardener Internship was an experience of a lifetime! Being able to learn about corals not just from a scientific perspective but also from a practical perspective was highly effective. Through the Ocean Gardener internship you realise that their coral restoration techniques not only emphasises on the fastest growing techniques but also methods that ensure diversity and longevity for our reefs! More importantly you learn how to introduce these same methods to local communities and get them involved in caring for the reefs too! It is a must for anyone who wants to start their journey in coral restoration work and carry on this much needed endeavour to protect our oceans. .”

“As a marine biology and ecology student I had to learn a lot of general theory in university about marine environment and I’ve always deplored the lack of a more down to earth and more useful knowledge. Something that I found within the Ocean Gardener’s course. Throughout the beginner and advanced courses I’ve acquired a deeper and more practical knowledge about marine environment, ecology and restoration techniques, knowledge that is really missing in the usual education you can get in universities. Courses are really made to be accessible at pretty much any level and really arouse your interest in recifal ecosystems. Overall a very pleasant experience with Ocean Gardener in an idyllic setting.” Master Biodiversité, Écologie, Evolution, Université des Science et Technologie du Languedoc, Montpellier, France
