According to the Smithsonian, every single year, as many as 220 black-footed ferrets are released into the wild. As a result, there are very few genetic differences between cheetahs. The Iberian lynx, California condor and pygmy hog are among animals that would have disappeared without reintroduction programmes, zoo-based conservation and formal legal protections since. Lemurs are squeezed into limited protected areas; 38 species are critically endangered. The species did not receive much attention in the late 19th century because it was considered feral and of little significance to humans.
