All of them went extinct in the wild — and all of them got here back, because of reintroduction applications.
Conservation scientists use translocation and captive breeding to re-establish animal populations which have died out in the wild — both totally or in sure areas. Reintroducing extinct-in-the-wild animals to their native territories is usually a double win: serving to to revive degraded ecosystems, in addition to growing inhabitants numbers.
But setting a species unfastened in the wild is a precarious balancing act. Reintroductions typically take years and contain a number of phases, says Natasha Robinson, an ecologist at the Australian National University who specializes in threatened wildlife.
Before bringing back a species, conservationists have to judge the menace stage — each to and from the animal — and the position it performed in the ecosystem, says Robinson. In locations the place wild populations have died out extra just lately, there’s a greater likelihood of success, she says.
“The less time that has passed, the more likely that environment is the same as when the species went extinct,” she says. “But you still need to address the reason why it went extinct in that environment to begin with.”
Predators are typically reintroduced slowly and punctiliously. While they are often helpful for managing pest species, conservationists have to make sure they do not overhunt or threaten different weak animals, says Robinson.
