When and Where to Restore Coral Reefs: The Key Role of Pre-Launch Assessment to Reef Restoration

Abstract

Coral recruitment is an important factor to coral reefs in maintaining their health. Currently, numerous coral reefs are facing extreme degradation, which protection and therefore rehabilitation practices are required to reverse. The present study explores the potential role of coral recruitment assessment by citizen scientists about the impacts of human influences towards coral reefs through measurement of coral recruitment values. Only a very small number of studies use forms of pre-launch assessment prior to reef restoration. These methods are able to properly guide vital decision-making information for reef rehabilitation methods and locations. In this initial study we observe significant relationships between reefs with higher coral recruitment values and their health. As compared to other average coral reef values, the reef we measured had higher recruitment values on average. Two sections of the reef had noticeably higher mean corals per square meter compared to average values, while a third section of the reef had a lower frequency. This section has been brought to concern through the pre-launch assessment, and has potential for rehabilitation through coral transplantation and a reduction of anthropogenic actions within the area.
