Our evaluation of the quantity of protected area (IUCN categories I-VI, plus NA lands) in each of the 391 ecoregions comprising the world's biological hotspots is summarized on this map. According to 2015 data 170 of the ecoregions have reached or surpassed the Aichi Target of 17% terrestrial area. 221 have not. If these 221 places of critically endangered biodiversity are to reach the Convention of Biological Diversity's global aim of 17% (representative) protected habitat they have until 2020 to do so.
