Since the publication of the IUCN/SSC Re-introduction guidelines in 1998, the number of re-introduction projects for animals and plants have steadily increased to cover virtually all taxa and habitats. The IUCN/SSC Re-introduction Specialist group has been created by a set of individuals dedicated to make re-introductions successful by providing clear guidelines to practitioners and various stakeholders in re-introduction efforts. The success of the guidelines is undeniable and very few documented re-introduction projects are made without at least consulting the guidelines and more often than not, re-introductions are making all possible efforts to follow the guidelines.
