Overview
• Established 1997 as part of the International year of the Reef (IYOR)
• Easy methodology ensures quick training with no prior knowledge necessary
• Results indicative of health of reef and anthropogenic impacts
• Now largest international coral reef monitoring program involving recreational divers and marine scientists
• Over 1500 trained volunteer divers surveying over 250 sites
• Result compiled by comparing fish and invertebrate species and substrate types which are indicators of the health of the reef

Reef check methodology:
• Site selection
• Site description
• Transect laying
• Fish survey belt
• Invertebrate survey (belt)
• Substrate survey (point sampling)
