This 8-panel fold-out chart is designed to enable you to identify lichens found on twigs and use them to assess local atmospheric conditions. Lichens are highly sensitive to subtle changes in environmental conditions, so are natural indicators of the health of our environment.
This key indicates which lichens are acid-tolerant and nitrogen-tolerant and also indicates lichens that are associated with unpolluted sites.
This chart is part of the FSC’s range of fold-out charts, designed to help users identify of a wide range of plants and animals. Each chart is laminated to make it splashproof and robust for use outdoors. Clear colour illustrations and text by experts in the subject make these valuable resources for all age groups.
