Survey methods involve divers recording fish and invertebrate species seen along underwater transects using underwater pencils & paper.
Although not high-tech, when undertaken by experienced surveyors, these methods allow coverage of species not able to be recorded by other methods, and are both cost- and time-effective. Underwater quadrats are also used to record coral or seaweed species and benthic cover on each survey.
The complete methods cover the majority of plants and mobile animals greater than 2.5cm in length that make up the life of rocky and coral reefs.
