保护生物学家越来越多地讨论的一个潜在的保护策略是将物种转移到其原生范围以外的有利栖息地，以保护它们免受人类引起的威胁，如气候变化。即使事先进行了仔细的风险评估，这种行动也可能产生无数意想不到和不可预测的后果。准确的风险评估受到偶然性的阻碍：在当地环境变量、种间相互作用和进化变化的影响下，引进物种的影响随时间和空间而变化。有些影响，如本地物种灭绝，是巨大的和不可挽回的。在这里，我们认为，保护生物学家还没有制定一个足够的了解引进物种的影响，作出明智的决定，物种易位。
A potential conservation strategy increasingly discussed by conservation biologists is the translocation of species to favorable habitat beyond their native range to protect them from human-induced threats, such as climate change. Even if preceded by careful risk assessment, such action is likely to produce myriad unintended and unpredictable consequences. Accurate risk assessment is impeded by contingency: the impacts of introduced species vary over time and space under the influence of local environmental variables, interspecific interactions and evolutionary change. Some impacts, such as native species extinctions, are large and irrevocable. Here we argue that conservation biologists have not yet developed a sufficient understanding of the impacts of introduced species to make informed decisions regarding species translocations.
