Taking stock of the assisted migration debate

摘要: Abstract Assisted migration was proposed several decades ago as a means of addressing the impacts climate change on species populations. While its risks and benefits have been debated, suggestions for planning management given, there is little consensus within academic literature over whether to adopt it policy. We evaluated main features assisted including study methods, taxonomic groups, geographic regions disciplines involved. further assessed debate about use migration, barriers consensus, range recommendations put forth in policy, or implementation. Commentaries secondary reviews were prevalent first-hand scientific research attention focussed global rather than regional level. There evidence knowledge transfer outside natural sciences, despite obvious policy relevance. Scholarly this topic has intensified during last 3 years. present conceptual framework evaluating arguments debate, distinguishing among direct species, ecosystems society one hand, other regarding justification, evidence-base feasibility other. also identify with potential advance careful evaluation risks, trade-offs, involvement relevant stakeholders consideration complementarity less risk-tolerant strategies. conclude, however, that none these will solve fundamental, often values-based, challenges debate. Solutions are likely be complex, context-dependent multi-faceted, emerging from research, discussion experience.
