The Conservation Learning initiative: improving the impact of conservation strategies

Working in partnership with the MAVA Foundation and Foundations of Success, we are excited to present the Conservation Learning Initiative.


Conservation on a wing and a prayer, or following the evidence?

Last month, we published our 25th synopsis, a global synthesis of evidence for conservation actions for butterflies and moths. Featuring 587 studies testing the effectiveness of 152 possible actions, and reviewed by 20 experts from around the world, the synopsis summarises evidence for the impact of interventions ranging from managing farmland in ways which might benefit insects to restoring degraded habitats, and from restricting chemical and light pollution to using translocations…


Plenty more fish in the… CE synopsis on Marine Fish Conservation!

The Marine Fish Synopsis aims to help researchers, fisheries managers and stakeholders address this exact need. This newly updated version of the synopsis (with additional actions) focusses on one of the main threats, overfishing – the harvesting of too many fish from the sea for populations to sustain themselves – and synthesizes the global evidence for effects of interventions to conserve fish numbers, or reverse the effects of sometimes decades of fish population decline.


“Show me the money!”: Poor reporting of costs of conservation interventions hampers ability to prioritize funds for nature

We reviewed 1,987 papers and found that only 8.8% of papers reported the total cost of the intervention being tested (White et al 2022). When papers did report costs, the reporting was often unstandardized and missing important information… This makes it difficult for conservationists to use this information, as it is difficult to know whether or not the costs are relevant to your circumstance.


New non-English language studies database: increasing the availability of conservation evidence

We are delighted to announce that we have now launched our non-English language database of studies testing conservation actions on our website. This forms part of our freely available Conservation Evidence resource of systematically-gathered evidence designed to help support conservation management or policy decisions…


The Conservation Evidence project — a truly collaborative and international effort

The Conservation Evidence database was created to provide an easily accessible, free, authoritative information resource to support decisions about how to maintain and restore global biodiversity. So far, we have worked with over eleven hundred named collaborators from across the globe, to create the database and to help facilitate a change to more evidence-based practice…


A brand new synopsis for reptile conservation

As we begin a brand new year, we are delighted to announce that the long awaited Reptile Conservation synopsis of evidence is finally here, produced by an international team of authors and advisors. But what actually is a “Reptile Conservation synopsis of evidence”…

Helping practitioners to make and document conservation decisions: the Evidence-to-Decision tool

When undertaking actions to restore habitats or conserve wildlife, we often have to make difficult decisions. Which actions are best to benefit bird species or pollinators? How effective will these actions be? Are they feasible to implement, and acceptable to other stakeholders? To make decisions, conservationists have to use and combine various sources of information […] and ensure that limited funds are used to maximum effect. […] Here I outline a new decision support tool developed jointly between conservation researchers and practitioners that helps to document the evidence and thinking behind decisions.

The biodiversity of marine artificial structures

In this new synopsis of evidence for the Conservation Evidence project, we have summarised the global evidence for the effects of actions that can be taken to enhance the biodiversity of marine artificial structures. We tried to include all the actions that could be taken – whether evidence of their effects existed or not. The actions are split into those that can be carried out on intertidal structures and those that can be carried out on subtidal structures…

The untapped side of science that could boost evidence-based conservation

On a quiet day over ten years ago in Cambridge, I was writing the summary of a paper reporting the creation of roof-top breeding sites for little terns (Sternula albifrons). Many people in the same lab were similarly writing paper summaries for the Conservation Evidence project, but there was one critical difference—the paper I was summarising was written in Japanese…
