This book brings together for the first time the published information on the Quaternary cold stage flora of over eighty sites in Britain and Ireland to present a factual cold stage flora from the fossil record. The data provides a basis for an interpretation of the flora, vegetation, and environments of some of the most extraordinary periods in the earth's most recent history, now only seen in the imperfect mirror of today's Arctic. This important study aims to reveal the nature of an environment, relatively stable, but completely different to that of today. As such, it will be significant to those interested in the Quaternary and also to a wider audience of those studying the present flora, fauna and environment, including climate and climatic change. A CD-ROM with a database of the cold stage flora in searchable format is included.
