These Guidelines define terms and set out guidance on the justification, design, and implementation of any reintroduction or conservation translocation, including (i) reinforcement and reintroduction within a species’ indigenous range, and (ii) conservation introductions, comprising assisted colonisation and ecological replacement, outside a species’ indigenous range. The Guidelines focus on conservation translocations, namely a translocation that yields quantifiable conservation benefit. For this purpose, the beneficiaries should be the population or the ecosystem of the translocated species. Translocation needs rigorous justification. Feasibility assessment should include a balance of the conservation benefits against the costs and risks of both the translocation and alternative conservation actions. There are multiple  risks in a translocation, affecting the focal species, their associated communities and ecosystem functions in both source and destination areas; there are also risks around human concerns. Any proposed translocation should have a comprehensive risk assessment.
