What are 'Individual studies' and 'Actions'?
Individual studies
An individual study is a summary of a specific scientific study, usually taken from a scientific journal, but also from other resources such as reports. It tells you the background context, the action(s) taken and their consequences.
If you want more detail please look at the original reference.
Actions
Each action page focuses on a particular action you could take to benefit wildlife or ecosystems.
It contains brief (150-200 word) descriptions of relevant studies (context, action(s) taken and their consequences) and one or more key messages.
Key messages show the extent and main conclusions of the available evidence. Using links within key messages, you can look at the paragraphs describing each study to get more detail. Each paragraph allows you to assess the quality of the evidence and how relevant it is to your situation.
Where we found no evidence, we have been unable to assess whether or not an intervention is effective or has any harmful impacts.
