We are losing global biodiversity at an alarming rate

This is a real risk to society and we need to be serious about reversing the trend. We have to ensure that conservation projects really work.

Our mission

Provide conservationists and policy makers with easy access to the latest and most relevant evidence-based knowledge, to support conservation policy or management decisions about how to maintain and restore global biodiversity.

What we do

Compiling Evidence

We collate and summarise evidence from the scientific literature (studies) about the effects of conservation actions such as methods of habitat or species management.

Assessing Evidence

Expert panels categorise the effectiveness (or not) of actions, based on the summarised evidence.

We publish the actions and the summaries of studies that test them on our website, an easy to use searchable database of all of the most up-to-date knowledge.

Championing Evidence

We promote the use of evidence to improve policy and practice including by building a network of Evidence Champions that commit to evidence use.

“We were delighted that the idea we found to be effective in our setting, and which we published in the Conservation Evidence Journal, was then picked up and used in a completely different conservation project over 6,000 miles away, which was also successful.”

Converting sea defences into natural rocky habitats that are better for marine biodiversity

Using methods developed by Conservation Evidence, Dr Evans collaborated with experts to create an evidence-based resource to help people plan, design and manage artificial structures that are better for marine biodiversity. It brings together the results of ecologists and engineers around the world who are already designing and testing new ideas.

Your donations make a real difference

Governments and private foundations have committed over $100 billion to conservation by the end of the decade.

We need to ensure this money is not wasted on activities that are believed to work, but which in reality do not.

We need to continually maintain a team of researchers to oversee and manage the collation and assessment of evidence.

In order to ensure that this knowledge is available to practitioners and policy makers it is vital that we continue to maintain and enhance our website platform.

We need continued support to promote what we do and to undertake proactive outreach to increase the number of Evidence Champions and others using evidence for conservation decisions.

Evidence Champions

Evidence Champions are organisations that have signed an agreement to make a clear commitment to include Conservation Evidence and other relevant sources of scientific evidence in decisions.

Becoming an Evidence Champion has many benefits. You will become part of a network of forward-thinking organisations creating a demand for evidence-based practice, and making conservation more effective.

Commitments can include:

  • Routinely including evidence in decisions.

  • Experimentally testing and publishing tests of management interventions.

  • Producing evidence-based guidance.

Conservation Evidence Website

Conservation Evidence Website

conservationevidence.com

We summarise the documented evidence for the effectiveness of conservation actions. This resource is designed to support anyone making decisions about how to maintain and restore biodiversity.

So far, in collaboration with an international group of over 500 experts, we have summarised the evidence for the effectiveness of over 3,600 conservation interventions for 24 species groups, habitats or other conservation issues. This has involved scanning over 1.6 million papers in more than 650 journals, including over 320 journals in 16 non-English languages.
