Conservation Evidence - Page Content

Introduction

We gather evidence by systematically searching key English and non-English scientific journals and identifying articles that fit our criteria. We also systematically search non-peer reviewed or unpublished sources.

Our ongoing review process continually extracts evidence from journals and other sources of evidence. So far we have searched over 330 English journals, with the searches of 30 important conservation journals (such as Conservation Biology, Biological Conservation, Ecology, Journal of Applied Ecology, Oryx) and systematic reviews published by the Collaboration for Environmental Evidence updated regularly. We have also searched over 330 non-English journals. In addition, we search 'grey literature', such as report series, to focus on particular species groups or habitats.

Additional specialist journals or report series, or additional years for those already listed, are frequently added to the list searched, for example when searches are undertaken for the production of a new synopsis.

Articles that fit our criteria are stored in our evidence repository until they are summarised and included in a synopsis and in our searchable database. For more details see our methods 'Finding evidence' and FAQ pages.

What studies have we searched for?

A conservation action must have been carried out. Browse our evidence for examples of conservation actions.
The effects of the action on wildlife or ecosystems must have been monitored quantitatively. There are a variety of relevant metrics for Conservation Evidence; we include metrics such as abundance, diversity, population trends, reproductive success, survival rate, percentage cover and establishment of a successful breeding population.
