What is the difference between Extinct and Endangered species?

Species assessed as Critically Endangered (CR), Endangered (EN), or Vulnerable (VU) are referred to as "threatened" species. However, Extinct in the Wild (EW) species can move into the threatened categories following successful reintroduction. Therefore, EW species should be included when reporting proportions of threatened species.
