The importance of conserving plant genetic diversity has been recognized since the 1980s, but genetic research tools for improving conservation remain largely absent from standard planning. Using an Australian case study framework of the New South Wales government's Saving our Species (SoS) programme, we outline the costs and benefits associated with conducting genomic analysis within a conservation strategy to inform, for example, taxonomic resolution, targeted monitoring, translocations and ex situ collections. Despite a reported sentiment that costs are prohibitive, our study identified that where genetics reports have been provided (32 to date), the cost of genetic sampling, analysis and advice is <10 % of the total government investment (SoS programme) and will continue decreasing proportionally throughout the years as other management occurs. We identified that the largest government investment was for maintenance and monitoring actions. On-ground practitioner feedback from the reports identified that the main reason for requesting genetics was to inform translocation or ex situ collection. However, from the total of 269 plant species with translocation or ex situ conservation actions planned, 75.4 % still do not have provisions for genomics, suggesting that knowledge of the utility of this practice is low among practitioners. Responsive feedback also demonstrated that 90 % of respondents seek additional learning, and thus there is merit in providing future genomics-focused workshops.
自20世纪80年代以来，保护植物遗传多样性的重要性已得到认可，但在标准规划中，用于改善保护工作的遗传研究工具仍基本缺失。利用澳大利亚新南威尔士州政府“拯救我们的物种”（SoS）计划的案例研究框架，我们概述了在保护策略中进行基因组分析所涉及的成本和收益，以便为分类学解析、针对性监测、物种迁移和迁地保护收集等工作提供信息。尽管有报道称成本过高，但我们的研究发现，在已提供遗传学报告的地方（截至目前有32份），遗传采样、分析和建议的成本不到政府总投资（SoS计划）的10%，并且随着后续其他管理工作的开展，这一比例将逐年持续下降。我们发现政府最大的投资用于维护和监测行动。报告中一线从业者的反馈表明，请求进行遗传学研究的主要原因是为物种迁移或迁地保护收集提供信息。然而，在计划采取物种迁移或迁地保护行动的269种植物中，仍有75.4%没有基因组学相关安排，这表明从业者对这种做法的实用性了解不足。回应性反馈还显示，90%的受访者寻求更多学习，因此举办未来以基因组学为重点的研讨会很有必要。
