Volume 3 in the British Wildlife Collection, Rivers is the definitive one-book study of this never-more-topical subject. Including detailed information about each of the huge variety of river-types to be found in Britain, discussion of individual examples both large and small, crucial insights into their maintenance and the dangers - felt so acutely in recent years across the UK - of their mismanagement, this is essential reading for serious conservationist and interested layman alike.
