Description: <DIV STYLE="text-align:Left;"><DIV><P><SPAN>Reef grid cells have been classified by estimated threat from overfishing and destructive fishing adjusted by management effectiveness of marine protected areas (MPAs). 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. Pressure from overfishing or destructive fishing was reduced in MPAs rated as having effective or partially effective management sufficient to reduce this threat. Effective MPAs reduced threat by two levels, and partially effective MPAs reduced threat by one level. This results in an "adjusted" threat estimate, where values of 0 indicate low threat, 100 indicate medium threat, 1000 indicate high threat. See the technical notes for additional information.</SPAN></P></DIV></DIV>
