Over the past few months we have had some coral nurseries at our artificial reef off Mae Haad but no real way to track the growth rate or quantify the data. So with this end in mind IDCS Nathan Cook of Eco Koh Tao joined some avid eco-divers to collect the first robust data of our small nursery.

Using a Quadrant survey method that we have employed locally on Koh Tao’s Biorock Nathan along with Master Instructor Jeff Glenn, Instructor Kati Pulli and Rescue Diver Martin Korndoefer took quantifiable data of our local nursery.

The visibility was not perfect but we managed to collect good information. Once back on dry land the team input the data into our spreadsheets determining that as a baseline we have 7% coverage on our 4 square metre nursery with most of that the branching variety of coral, acropora. Over time we hope this grows and will keep tracking and collating the results.
