Conservation

Fishing and ornamental fish collection are the main economic usages of the coral reef. The pigeon island is also used as a scuba diving site. Uncontrolled tourism has resulted in reef degradation and loss of biodiversity and fish density. Scientific research was hindered due to the civil war in the past two decades. A proposed pier between the mainland coast and the island has attracted criticism.
