The complex structures created by hard corals provide habitats to a variety of different reef fish and invertebrates. These structures are formed when corals deposit calcium carbonate (limestone). As they become larger, hard coral structures may be easily broken from mechanical damage. This may be caused naturally by storms, but also occurs as a result of human impacts e.g. divers colliding with corals or the use of heavy anchors in areas that significant coral cover.

Passive Restoration Mooring Lines
Passive restoration methods aim to address specific threats that impact reef health by creating conditions that will enhance the survival and growth of corals. Installing mooring lines in reef areas which are frequently visited by boats is an extremely effective reef conservation method, minimising damage caused by anchors. The ecoTrust have worked alongside the Thai government’s Department of Marine & Coastal Resources (DMCR) in establishing and maintaining mooring lines in order to prevent the use of anchors in areas where diving and fishing practices are common. This has had a significant positive impact on reefs where mooring lines are commonly used.
