"The rarest wolf species, red wolves (Canis rufus) almost went extinct by the middle of the 20th century. First, they were nearly eradicated in order to protect livestock. Then coyotes started moving into their territory, where they hybridized with the wolves. By the time the last red wolves were brought into captivity in 1973, only 14 pure individuals remained. Today that population has increased to nearly 200 wolves living in captive-breeding centers and about another 120 in the wild in northeastern North Carolina. Like Mexican gray wolves, that wild population is classified as an experimental nonessential population. Also, like their Mexican relatives, the wild population has been heavily hit by illegal hunting, with at least 10 animals killed since the beginning of 2012. As I wrote earlier this year, those deaths bear heavy penalties under the Endangered Species Act, and the FWS is seeking information on anyone responsible for the killings."  -scientific American: website
