From Wikipedia, the free encyclopedia

[edit] Reintroduction
Reintroduction is the deliberate release of species into the wild, from captivity or relocated from other areas where the species survives. It usually involves species that are endangered or extinct in the wild.
It may be very hard to reintroduce EW species into the wild, even if their natural habitats were restored. A main reason may be that the survival techniques, which are normally passed from parents to offspring during parenting, are lost. In other words it may be explained by that the genetics of the species is saved, but the natural memetics of the species is lost.
