Chapter 8 Chapter Summary

  New populations of rare and endangered species can be established in the wild using either captive-raised or wild-caught individuals; new populations can also be established outside the historical range of a species.

  Identifying and reducing threats to a species is a key element in the success of reintroduction programs.

  Animals sometimes require behavioral training before release as well as maintenance after release.

  Ex situ conservation is the preservation of individuals and populations in captivity. Zoos, aquariums, botanical gardens, and seed banks play an important role in conservation, highlighting the complementary roles of in situ and ex situ conservation.

  Technologies are being developed that could potentially revive versions of extinct organisms; however, this may neither be practical nor advisable.
