Lichens of heaths and moors guide
The FSC Lichens of heaths and moors guide will help you identify 62 of the commonest lichens from dry sandy heaths to wet peaty moorland.
Colour photographs are grouped into species that grow on the ground, among grasses and mosses, on heather, and on small rocks and pebbles.
Lichens are present throughout the year and may be searched for at any time.
Lichens are highly sensitive to subtle changes in environmental conditions. So they are useful as natural indicators of the health of our environment. In the past sulphur dioxide from coal burning and industry was the main pollutant. It was a major cause of acid rain. But today nitrogen compounds from intensive farming and motor vehicle exhausts are becoming the main pollutant. Although pollutants can kill many lichens, other lichens tolerate, or even depend on them. This guide indicates which lichens are acid-tolerant and nitrogen-tolerant, and also which lichens grow in unpolluted sites.
