About Synopses

What is a synopsis?

A synopsis of evidence reviews the effectiveness of all the possible actions you could take to conserve a given species group or habitat or to tackle a particular conservation issue. 

See all synopses.

For each action, a synopsis brings together the available scientific evidence with short summaries that are quick and easy to read. For each piece of evidence it describes the background context, action taken and consequences, with references and links to more information on our website.

Each synopsis is developed in partnership with an international advisory board of conservationists and researchers who specialise in that area.

For more information about the methods used for these synopses please see the methods and protocols, and for evidence sources see here for all sources or the catalogue of journals searched: by synopsis.

As well as the completed synopses, a number of global conservation synopses are currently being produced (see protocols). Additional topics are also being added to the synopsis on the control of invasive species. We are also currently updating the synopsis on the conservation of birds.


Here is a short animation about one of the synopses: Enhancing the Biodiversity of Marine Artificial Structures.
