Reef survey Rarotonga 2006

Coral Reef Cover and Fish

Data presented in this survey provides a snap-shot of present conditions around Rarotonga, however time series data obtained from continuous monitoring of all fore reef and lagoon sites may enable us to identify changes at the community level that may be related to land based activities. Multi-Dimensional Scaling analyses of fore reef corals and fish (by trophic level) between windward and leeward exposures indicated differences between groups. It will be of value to monitor changes within these groups over time, as they may indicate direct or indirect impacts from land-based activities.
