The importance of using evidence in decision-making is frequently highlighted in policy reports and scientific papers. However, subjective judgments of the reliability of environmental evidence vary widely, and large-scale systematic searches for evidence are only common for climate-related topics. In the medical field, evidence-based guidelines are routinely used to guide treatments. In the management of multiple-use landscapes similar guidelines could substantially narrow the science-practice gap but are largely absent. The challenges potential guidelines face are therefore unknown. For the case of forest conservation, we conducted 14 semistructured interviews with mainly forest practitioners and presented them an example medical guideline together with evidence-based statements on forest conservation (hereinafter: statement paper). We identified 28 concerns related to potential evidence-based guidelines in forest conservation. The interviews yielded approximately three major findings. First, recommendations on forest conservation are better accepted if they include clear instructions and are formulated for a specific context. Fragmentary conservation evidence complicates the formulation of specific recommendations. Second, the level of evidence framework, which indicates the strength of the available evidence, is perceived as too complex. Third, neglecting forest multifunctionality in a potential guideline hampers its application but, if addressed, potentially weakens its ecological relevance. We show that major concerns about potential evidence-based conservation guidelines are similar to the challenges experienced by medical guidelines. We also identify concerns unique to forestry.

对保护管理循证指南方法的关注探索：来自医疗实践的提示

政策报告和科学论文中经常强调在决策中使用证据的重要性。然而，对环境证据可靠性的主观判断差异很大，大规模系统的证据搜索仅针对与气候相关的主题常见。在医学领域，循证指南通常用于指导治疗。在多用途景观的管理中，类似的指导方针可以大大缩小科学与实践的差距，但基本上不存在。因此，潜在指南面临的挑战是未知的。对于森林保护的案例，我们主要对森林从业者进行了 14 次半结构化访谈，并向他们展示了医学指南示例以及森林保护的循证陈述（以下简称：陈述文件）。我们确定了 28 个与森林保护潜在循证指南相关的问题。访谈产生了大约三个主要发现。首先，如果有关森林保护的建议包含明确的说明并针对特定背景制定，则更容易被接受。零碎的保护证据使具体建议的制定变得复杂。其次，表明可用证据强度的证据框架级别被认为过于复杂。第三，在潜在准则中忽视森林多功能性会阻碍其应用，但如果得到解决，可能会削弱其生态相关性。我们表明，对潜在循证保护指南的主要担忧与医学指南面临的挑战相似。
