Conservation synopses collate multiple sources of evidence for a broad question. A list of actions that conservationists may employ for a particular species group, habitat or conservation issue is drawn up using an advisory board of experts. These actions are organised into categories based on the International Union for the Conservation of Nature (IUCN) classifications of direct threats and conservation actions. In some cases recognised systematic searching methodology is used to collate evidence relating to the actions eg. systematic mapping but this is not always the case. Synopses only include studies that have quantitatively monitored the effect of an action. They describe existing evidence in summary paragraphs but do not make any recommendations on which action to take. For an example of a conservation synopsis that used systematic mapping please click here. For more information about conservation synopses please go to the Conservation Evidence website.
