Conservation action must be based on sound scientific evidence if it is to be effective. Butterfly Conservation undertakes scientific research in collaboration with universities and other organisations around the world in order to provide such evidence.

Our aim is always to publish such research in peer-reviewed journals and, where possible, to make these papers accessible to the public without charge (indicated by * in the publication list below). Much of our research is based upon data gathered through our world-leading recording and monitoring schemes.
