6. Red Wolf – The comeback kids of the rarest animals list
The red wolf is one of the most threatened species in the world and was declared extinct in the wild by 1980. However, the US Government reintroduced it in 1987 in Eastern North Carolina. The reintroduction has been successful in that more than 150 red wolves have eventually been established in the region. However, their rapid growth brought about concerns over crossbreeding with coyotes and conflicts among area landowners. Because of this, the US federal government reduced the programs to cover only those federal lands in the easternmost part of North Carolina. Right now, the population of red wolves is believed to be declining.
