Welcome to the British Lichen Society
The British Lichen Society welcomes all who are interested in lichens, whether you are a complete beginner or someone with a life-time’s experience of lichenology. Throughout the world, but with a special emphasis on the British Isles, our aims are:
- to promote and advance the teaching and study of lichens;
- to encourage and actively support the conservation of lichens and their habitats;
- to raise public awareness of the beauty of lichens and of their importance as indicators of the health of our environment.
We work towards these aims through field meetings, workshops and recording projects. Our Bulletin is packed with information about lichens, lichenologists and events, and we also publish a highly regarded scientific journal, The Lichenologist.
About Lichens
Learn about the fascinating dual nature of lichens and how two completely different types of organisms come together to make something quite new. Find here also information on lichen ecology, habitats and conservation.
Churchyard Lichens
Churchyards in unpolluted areas provide extremely important refuges for many lichens. The BLS has a group dedicated to the study and conservation of churchyard lichens.
Join and Renew
