从制定目标到使用工具和战略，决策是恢复实践的核心。然而，在很大程度上仍然不清楚在恢复期间如何作出决定，这限制了对恢复管理人员如何设计和实施恢复项目以及哪些恢复方法可能最有效的了解。美国中西部的高草草原就是如此，通常通过播种来恢复。为了了解管理者在草原恢复过程中是如何做出决策的，我们采用了包括访谈、焦点小组和在线调查在内的混合方法，询问管理者：恢复目标、影响种子配方设计的因素、种子配方设计中使用的工具和资源、播种方法和监测。受访者认为生物多样性是最重要的恢复目标，最重要的生物多样性衡量标准是物种丰富度和功能群多样性。种子组合设计受种子可用性的影响。我们确定了141个管理者想要用于恢复的分类群，但由于成本、可用性或萌发或建立问题等因素而无法使用。管理人员最常使用自己的经验和与其他从业者的咨询来指导种子配方设计；以及在其组织内开发的常用工具。大多数管理人员同意，监测对于评估恢复成果很重要，但无法投入足够的时间进行监测。这些发现说明了修复管理人员之间以及管理人员、种子生产者和研究人员之间建立伙伴关系的机会。
Decision‐making is central to restoration practice, from the framing of objectives to the employment of tools and strategies. Yet, it remains largely unclear how decisions are made during restoration and this limits understanding of how restoration managers design and implement restoration projects and what restoration approaches may be most effective. This is true for tallgrass prairies in the Midwestern United States, which are commonly restored through seed sowing. To understand how managers make decisions during prairie restoration, we used a mixed‐methods approach including interviews, a focus group, and an online survey, to ask managers about: restoration objectives, factors influencing seed mix design, tools and resources used in seed mix design, seeding methods, and monitoring. Respondents considered biodiversity the most important restoration objective, and the most important biodiversity measures were species richness and functional group diversity. Seed mix design was influenced by seed availability. We identified 141 taxa that managers would like to use in restoration, but cannot due to factors like cost, availability, or problems with germination or establishment. Managers most frequently used their own experience and consultation with other practitioners to guide seed mix design; and commonly used tools developed within their organization. Most managers agreed that monitoring was important for assessing restoration outcomes, but were unable to devote enough time to monitoring. These findings illustrate opportunities for partnerships, among restoration managers, and among managers, seed producers, and researchers.
