The Coral Health Chart can be used while diving, snorkeling or reefwalking. You can choose a monitoring method that suits your skills, experience and location. Most people use the random survey method.
Select corals randomly.
Swim in an imaginary line and choose the closest coral after every second fin kick ( or every second step when walking).
Select corals by following a line (transect) and record your findings every few meters.
Make sure that the transect has no affect on marine life.
Permanent transect/Easy to identify
Select corals you can easily recognise and return to. A permanent transect would give you the opportunity to monitor the same corals over time. CoralWatch has established 2 permanent transect on Heron Island and one on Lady Elliot Island.
