Reliability of scienti c ndings is important, especially if they directly impact decision making, such as in environmental management. In the s, assessments of reliability in the medical eld resulted in the development of evidence-based practice. Ten years later, evidence-based practice was translated into conservation, but so far no guidelines exist on how to assess the evidence of individual studies. Assessing the evidence of individual studies is essential to appropriately identify and summarize the con dence in research ndings. We develop a tool to assess the strength of evidence of ecosystem services and conservation studies. is tool consists of ( ) a hierarchy of evidence, based on the experimental design of studies and ( ) a critical-appraisal checklist that identi es the quality of research implementation. e application is illustrated with examples and we suggest further steps required to move towards more evidence-based environmental management.
In a nutshell• Human's life depends on nature, biodiversity and their related ecosystem services and it is essential to manage natural ecosystems in a sustainable way.• Decisions taken in the context of environmental management need to be based on sound knowledge and reliable information.• We introduce an evidence assessment tool to identify the reliability of environmental research.• is evidence assessment tool is based on a hierarchical ranking of study designs and a study quality checklist.• Identifying the reliability of environmental research is the rst step towards more e ective decision making..

Next, we introduce a new evidence hierarchy that ranks scienti c study designs in ecosystem services and conservation, extending a previous proposal by Pullin and Knight ( ). A quality checklist will support the appraisal of the study design and increase reproducibility.Finally, we illustrate the application of the tool with case studies, and specify the relevance of evidence-based practice for di erent user groups.
