Rehabilitation and translocation programmes are increasingly becoming an important component of conservation action plans for threatened species. Translocation can help address gibbon conservation issues (gibbons are recognized as one of the most threatened primate families globally) by allowing gibbons held in captivity to be rescued, rehabilitated and then returned to the wild. These guidelines for the translocation of gibbons have been developed in collaboration with stakeholders in hylobatid conservation. This process was initiated druing a workshop on gibbon rehabilitation, reintroduction and translocation, facilitated by the IUCN SSC PSG Section on Small Apes (SSA), and the result of this process is the current document, which is based on shared knowledge and experience to date. The guidelines are designed to be a practical and useful document available for all stakeholders, with the aim of equipping field projects and decision makers with the tools for scientifically sound practice in gibbon rehabilitation and translocation.
