Australia and the United States have large no-take marine reserves. The data completeness may be quite poor, and the structure of the way this information is reported in the database makes it difficult to resolve overlaps or to reconcile the different areal measurement techniques used, therefore these figures should be used with caution. This is particularly important for countries such as the United States, France, Australia and the United Kingdom as these countries (with their overseas affiliated territories, which are generally small islands) account for large share of global EEZ area. In some cases, such overseas MPAs account for a greater share of the total MPAs for a country than those within the domestic EEZ.
