2.2 Census Method
2.2.1 Underwater Visual Census Approach
The visual census methods of Edgar and Barrett (1997, 1999; Edgar et al. 1997) are used for
this monitoring program. These are non-destructive and provide quantitative data on a large
number of species and the structure of the reef communities. The Edgar-Barrett method is
also used in Tasmania, New South Wales, South Australia and Western Australia. The
adoption of this method in Victoria provides a systematic and comparable approach to
monitoring reefs in southern Australia. The survey methods include practical and safety
considerations for scientific divers and are designed to maximise the data returns per diver
time underwater. The surveys in Victoria are in accordance with a standard operational
procedure to ensure long-term integrity and quality of the data (Edmunds and Hart 2003).
