9 – Black-footed Ferret – a success story for conservationists
The black-footed ferrets are among those species that have been touted as a conservation success story since they have come back from extinction status twice with the help of conservationists. These species are native to the Great Plains of North America and are roughly the size of a mink and similar in appearance to the European polecats. Throughout the 20th Century, their population has sharply declined, and they were declared extinct in 1979. But a few years later, they were re-discovered in Wyoming. Since then, a captive breeding program was launched and was mostly a success. Still, their population remains at around 300, making them one of the rarest animals in the world.
