African lions are set to gain greater international protection this year in the wake of the killing of Cecil by an American dentist in Zimbabwe. Tough new US regulations on the importation of lion trophies will come into force on January 22. The number of lions in Africa has declined by half since the 1990s. Global attention was focused on the dilemma of the African lion after Minnesota dentist Walter Palmer killed Cecil, who had been tempted from Zimbabwe’s Hwange National Park, last July. In December, the US Fish and Wildlife Service announced that lions from central and western Africa would be classified as endangered while those from southern and eastern Africa would be seen as threatened. The move will make it significantly more difficult to import lion heads, paws or skins from all parts of the continent.
