The conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species.

It is the process of protecting an endangered species of plant or animal outside its natural habitat.

*Conservation of species in their natural habitats.

*Preservation of components of biological diversity outside their natural habitats

* The endangered species are protected from all adverse factors.

*The endangered species are protected from predators.

*The depleting resources are augmented.

*They are kept under human supervision and provided all the essentials.

*The population recovers in natural environment.

*Offspring produced in captive breeding are released in natural habitat for acclimatization.

*Conservation requires large areas of earth's surface.

*Rarely enough to save a species from extinction.

*Ex situ conservation techniques are often costly.

*Does not assist in the international sharing of genetic material.
