*We are currently updating our dataset to reflect peer-reviewed classification systems which expand the assessment of human impacts to include uses such as mining, infrastructure and non-extractive use in order to more accurately report the types of protection globally. In the meantime, we are using our fishing protection scores to rank countries and MPAs by size and percent of protection. This number will be replaced when the database is robust enough to include the additional criteria. Until that time, the fully and highly protection used for ranking comes from the MPA Guide fishing protection criteria score, the RBCS fishing protection score, or confirmation of no-take status reported by the WDPA.
