Titre original : Biological and physical restoration of a French Polynesian damaged reef site : success and frustration.
The present work reports on a reef restoration project conducted at a large spatial scale (20,000 m2) in the lagoon of Bora Bora (Matira’s Point), French Polynesia. The fringing reef flat of the south part of the island was significantly degraded by coral quarrying in the last 50 years, leading to an increase of coastal erosion. The restoration was dual, combining both physical and biological restoration techniques. The physical restoration required principally the filling in of extraction pits and the establishment of a breakwater structure composed of artificial concrete blocks. The biological restoration involved the creation of a coral garden by coral transplantations onto artificial blocks or onto the seabed.
