FSC Lichens on twigs guide

The FSC Lichens on twigs identification guide will help you identify 60 of the commonest lichens found growing on trees and shrubs in Britain. The lichens are grouped according to growth form.

Lichens are highly sensitive to subtle changes in environmental conditions, so are natural indicators of the health of our environment. This chart indicates which lichens are acid-tolerant and nitrogen-tolerant and also indicates lichens that are associated with unpolluted sites.

The FSC Lichens on twigs guide was produced in partnership with the British Lichen Society.
