This edition is exclusive to newnaturalists.com Lichens are fascinating and beautiful organisms able to colonise a vast range of habitats, including seemingly impossible places such as bare icy mountain tops and sun-scorched coastal rocks. This book discusses all aspects of British lichens, revealing the secrets of their success. The book begins 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 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. Gilbert also discusses the susceptibility of lichens to air pollution, and how they can be used to detect environmental pollution. The comprehensive, reader-friendly text, over 150 illustrations and 16 pages of colour, combine to make Lichens the definitive work on this subject of great natural history interest.
