Coral reefs classified by threat from overfishing and destructive fishing (adjusted for management)

Reef polygons have been classified by estimated threat from overfishing and destructive fishing. Threats to coral reefs from overfishing were evaluated based on coastal population density and extent of fishing areas (reef and shallow shelf areas), with adjustments to account for the increased demand due to proximity to large populations and market centers. Areas where destructive fishing occurs (with explosives or poisons) were also included, based on observations from monitoring and mapping provided by experts. Values of 0 indicate low threat, 100 indicate medium threat, 1000 indicate high threat.
