The map shows the percentage of coverage within each country of the terrestrial ecoregions. The statistics were computed using the World Database of Protected Areas (WDPA) from January 2019 and ecoregion maps defined by Olsen et al. (2001) and Spalding et al. (2007). The analysis used all designated protected areas recorded in the WDPA as polygons, or points with a reported area, except for UNESCO Man and Biosphere Reserves because many of their buffer areas do not meet the protected area definition of the International Union for Conservation of Nature (IUCN).
