Reintroduction of genetically distinct orangutan subspecies has led to hybridization in an endangered wild population

As their natural habitats continue to be destroyed, increasing numbers of displaced endangered mammals are taken to sanctuaries and rehabilitation centres worldwide. The ultimate goal of these centres is often reintroduction: to return these animals to wild populations.
