New Naturalist Lichens

de Oliver Gilbert, Gilbert

"The book starts by looking at how lichens have been used throughout history in medicines, dyes, food and perfumes. It then goes on to describe what lichens are, and how they grow and reproduce. A detailed survey is then given of the range of habitats in which lichens can be found: on trees, rocks, heaths and moors, chalk and limestone, mountains, rivers, lakes, the coast, walls and buildings, most famously on churches and in churchyards. Drawing on his broad experience in this field, Gilbert also discusses the susceptibility of lichens to air pollution, and how they can be used to detect levels of environmental pollution."--Jacket.
