Reintroduction

From Wikipedia, the free encyclopedia

Reintroduction is the deliberate release of animals from captivity into the wild. It usually involves species that are endangered or extinct in the wild. In some cases, reintroduction involves a species that had been wiped out in a particular ecosystem, but survived elsewhere in the wild. Given that reintroduction normally involves native species that have become (locally) extinct, some prefer the term "re-establishment".

Beginning in the 1980s, biologists have learned that many mammals and birds need to learn a lot in order to survive in the wild. Thus, reintroduction programmes have to be planned carefully, ensuring that the animals have the necessary survival skills. It is also necessary to study the animals after the reintroduction. The goals of this study include learning whether the animals are surviving and breeding, and what effects the reintroduction is having on the ecosystem, and to learn how to improve the process.

[edit] IUCN/SSC Re-introduction Specialist Group

The IUCN/SSC Re-introduction Specialist Group (RSG) 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.

Asiatic Lion Reintroduction Project of Asiatic Lion to Kuno Wildlife Sanctuary from their only home presently in the world at Gir Forest National Park. Kuno Wildlife Sanctuary is the chosen site for re-introducing and establishing the world's second completely separate population of the wild free ranging Asiatic Lions in the state of Madhya Pradesh, India.
