Mitigation translocations are increasingly used worldwide in response to land planning pressures. The quality of translocation protocols and their adjustment to the ecological traits of the translocated populations are crucial to optimise translocation success. We studied the quality of translocation protocols presented in derogation requests, a mandatory step in France to translocate a protected plant species. We analysed 103 translocation proposals for 93 different species in 92 files examined between 2018 and 2020. After tracing the history of the place of translocations in legal procedures in France, we assessed each translocation proposal according to an evaluation grid, which involved the quantity and quality of information on plant species and translocation sites in the files and the quality of translocation protocols. We have shown that the translocation protocols are of low quality, with a lot of missing information. The biology and ecology of the species suggested for translocation are not sufficiently known, nor are the ecological characteristics of the host sites. Derogation requests that received a favourable opinion from the assessment body are more likely to propose a protected host site and post-translocation monitoring. We believe that, to optimise their outcome, mitigation translocations need to be improved upstream, with more detailed protocols and better species knowledge. We highly recommend following the same guidelines for mitigation translocations as for conservation translocations.
缓解性转移（Mitigation translocations）在应对土地规划压力方面在全球范围内得到了越来越多的应用。转移协议的质量及其对转移种群生态特征的调整对于优化转移成功率至关重要。我们研究了法国境内为保护植物物种而进行的规避性转移（derogation）申请中所涉及的转移协议的质量。在 2018 年至 2020 年期间，我们分析了 92 份文件中的 103 个针对 93 个不同物种的转移提案。在追踪了转移地点在法国法律程序中的历史之后，我们根据评估表评估了每个转移提案，该评估表涉及文件中关于植物物种和转移地点的信息量和质量，以及转移协议的质量。我们发现，转移协议的质量较低，信息缺失较多。对于建议进行转移的物种的生物学和生态学了解不足，对宿主地点的生态特征也了解不足。那些从评估机构获得有利意见的规避性转移申请更有可能提出保护宿主地点和转移后监测的建议。我们认为，为了优化转移结果，需要在上游阶段改进缓解性转移，制定更详细的协议和更好地了解物种。我们强烈建议对缓解性转移采用与保护转移相同的指导方针。
