**About the tool**
The Evidence-to-Decision tool has been co-designed between Conservation Evidence and practitioners from several organisations to help guide practitioners through the process of making an evidence-based decision. The tool is structured to help you consider and combine several forms of evidence (e.g., scientific evidence, tacit knowledge, values, costs) to reach a transparent decision, documenting each stage of the process so that the logic and reasoning behind decisions can be open and traceable. Access the online tool by clicking the green button, or if you wish to use an offline template of the tool please click on the appropriate blue button (a recommended user guide is also available there to help you use the tool).
**Availability**
The Evidence-to-decision tool is available at www.evidence2decisiontool.com.
