What other types of evidence/resources are there?
Systematic reviews (see www.environmentalevidence.org) are detailed evaluations of the evidence for specific policy-relevant questions. They comprise an exhaustive literature search, and usually incorporate meta-analysis that weight or value individual studies according to experimental rigour. Systematic reviews relating to conservation interventions are summarised on the Conservation Evidence database.
There are a number of platforms that provide case studies and grey literature. These include PANORAMA (https://panorama.solutions/en), The Open Standards (https://cmp-openstandards.org/), and Applied Ecology Resources (https://www.britishecologicalsociety.org/applied-ecology-resources/). For access to theses and dissertations, which are often not written up as academic papers, you can use Open Access Theses and Dissertations (https://oatd.org/). You can also check the websites of governmental organisations or NGOs for any relevant reports.
Evidence can be described as any relevant information used to assess one or more hypotheses related to a question of interest, such as scientific evidence, local knowledge, indigenous and traditional knowledge and experiential knowledge and expert opinion.
Scientific evidence specifically refers to information that has been collected using a scientific method. This includes published, peer-reviewed studies and unpublished studies in theses or reports.
