Shetland Lichens

120pp, col and b&w illustrations, map. What are Lichens? is the opening question, and we are enlightened in the introductory section, well-illustrated with Claire Dalby’s drawings. Next comes an Outline of Shetland Habitats, factors affecting lichens, Conservation, History of Lichen Studies in Shetland, and finally The Shetland Lichen List itself, with those species in the IUCN threat categories printed in red. Details the islands where each species has been recorded, and gives taxonomic and habitat notes.
