Extinct: No reasonable doubt that the last individual has died. EW: Extinct in the wild: Known only to survive in captivity or as a naturalized populations well outside its previous range. CR: Critically endangered: The species is in imminent risk of extinction in the wild. EN: Endangered: The species is facing an extremely high risk of ...
