Reintroduction is the deliberate release of a species into the wild in zones formerly inhabited by said species but where it has disappeared from for a number of reasons, from captivity or relocated from other areas where the species still survives in. It usually involves species that are endangered or extinct in the wild (EW).

[edit] Survival skills

It may be very hard to reintroduce EW species into the wild, even if their natural habitats were restored. Survival techniques, which are normally passed from parents to offspring during parenting, are lost. The genetics of the species is saved, but the natural memetics of the species is not.

Beginning in the 1980s, biologists have learned that many mammals and birds need to learn a lot to survive in the wild. Thus, reintroduction programmes have to be planned carefully, ensuring that the animals have the necessary survival skills. Biologists must also study the animals after the reintroduction to learn whether the animals are surviving and breeding, what effects the reintroduction has on the ecosystem, and how to improve the process.

Still, a vast number of animals may need to be reintroduced into the wild to be sure that enough of them learn how to survive. For instance, in reintroducing Houbara Bustards into the wild in the United Arab Emirates, more than 5,000 birds per year are used.[1]

[edit] IUCN/SSC Re-introduction Specialist Group

The IUCN/SSC Re-introduction Specialist Group (RSG)[2] is one of the over 100 Specialist groups of the Species Survival Commission (SSC), which is one of the six IUCN Commissions, with its headquarters in Gland, Switzerland. The RSG is one of the few disciplinary Specialist Groups (e.g. Veterinary, Conservation Breeding) as opposed to the majority which are taxon based (e.g. Crocodile, Cat, Orchid).

The role of the RSG is to promote the re-establishment of viable populations in the wild of animals and plants. The need for this role was felt due to the increased demand from re-introduction practitioners, the global conservation community and increase in re-introduction projects worldwide.

Increasing numbers of animal and plant species are becoming rare, or even extinct in the wild. In an attempt to re-establish populations, species can – in some instances – be re-introduced into an area, either through translocation from existing wild populations, or by re-introducing captive-bred animals or artificially propagated plants.
