Mitigation translocation is a subgroup of conservation translocation, categorized by a crisis-responsive time frame and the immediate goal of relocating individuals threatened with death. However, the relative successes of conservation translocations with longer time frames and broader metapopulation- and ecosystem-level considerations have been used to justify the continued implementation of mitigation translocations without adequate post hoc monitoring to confirm their effectiveness as a conservation tool. Mitigation translocations now outnumber other conservation translocations, and understanding the effectiveness of mitigation translocations is critical given limited global conservation funding especially if the mitigation translocations undermine biodiversity conservation by failing to save individuals. We assessed the effectiveness of mitigation translocations by conducting a quantitative review of the global literature. A total of 59 mitigation translocations were reviewed for their adherence to the adaptive scientific approach expected of other conservation translocations and for the testing of management options to continue improving techniques for the future. We found that mitigation translocations have not achieved their potential as an effective applied science. Most translocations focused predominantly on population establishment- and persistence-level questions, as is often seen in translocations more broadly, and less on metapopulation and ecosystem outcomes. Questions regarding the long-term impacts to the recipient ecosystem (12% of articles) and the carrying capacity of translocation sites (24% of articles) were addressed least often, despite these factors being more likely to influence ultimate success. Less than half (47%) of studies included comparison of different management techniques to facilitate practitioners selecting the most effective management actions for the future. To align mitigation translocations with the relative success of other conservation translocations, it is critical that future mitigation translocations conform to an established experimental approach to improve their effectiveness. Effective mitigation translocations will require significantly greater investment of time, expertise, and resources in the future.

缓解易位作为一种管理工具

缓解易地是保护易地的一个子组，按危机响应时间框架和迁移面临死亡威胁的个人的直接目标分类。然而，具有较长时间框架和更广泛的元种群和生态系统层面考虑的保护易地的相对成功已被用来证明在没有足够的事后监测以确认其作为保护工具的有效性的情况下继续实施缓解易地的合理性。缓解易位现在超过其他保护易位，鉴于全球保护资金有限，特别是如果缓解易位因未能拯救个人而破坏生物多样性保护，了解缓解易位的有效性至关重要。我们通过对全球文献进行定量审查来评估缓解易位的有效性。总共审查了 59 个缓解易地，以确保它们遵守其他保护易地所期望的适应性科学方法，并测试管理选项以继续改进未来的技术。我们发现缓解易位尚未发挥其作为有效应用科学的潜力。大多数易位主要关注种群建立和持久性级别的问题，这在更广泛的易位中经常看到，而不是集中种群和生态系统结果。尽管这些因素更有可能影响最终的成功，但关于对接受者生态系统的长期影响（12% 的文章）和易位站点的承载能力（24% 的文章）的问题很少得到解决。不到一半 (47%) 的研究包括不同管理技术的比较，以帮助从业者选择未来最有效的管理行动。为了使缓解易位与其他保护易位的相对成功保持一致，未来的缓解易位必须符合既定的实验方法以提高其有效性。有效的缓解易位将需要在未来投入更多的时间、专业知识和资源。尽管这些因素更有可能影响最终的成功。不到一半 (47%) 的研究包括不同管理技术的比较，以帮助从业者选择未来最有效的管理行动。为了使缓解易位与其他保护易位的相对成功保持一致，未来的缓解易位必须符合既定的实验方法以提高其有效性。有效的缓解易位将需要在未来投入更多的时间、专业知识和资源。尽管这些因素更有可能影响最终的成功。不到一半 (47%) 的研究包括不同管理技术的比较，以帮助从业者选择未来最有效的管理行动。为了使缓解易位与其他保护易位的相对成功保持一致，未来的缓解易位必须符合既定的实验方法以提高其有效性。有效的缓解易位将需要在未来投入更多的时间、专业知识和资源。为了使缓解易位与其他保护易位的相对成功保持一致，未来的缓解易位必须符合既定的实验方法以提高其有效性。有效的缓解易位将需要在未来投入更多的时间、专业知识和资源。为了使缓解易位与其他保护易位的相对成功保持一致，未来的缓解易位必须符合既定的实验方法以提高其有效性。有效的缓解易位将需要在未来投入更多的时间、专业知识和资源。
