The lion (Panthera leo) is one of the big cats in the Felidae family and a member of genus Panthera. It has been listed as Vulnerable on the IUCN Red List since 1996, as populations in African range countries declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes of concern.[3] The West African lion population is listed as Critically Endangered since 2016.[5] The only lion population in Asia survives in and around India's Gir Forest National Park and is listed as Endangered since 1986.
