This is a book about understanding fens, bogs and marshes. It concentrates on habitat, vegetation and animals and human impact, and the interactions between them. It is intended as an introduction for universities and colleges, conservation organisations and the Environment Agency, and indeed for sixth-form and further education work. It is comprehensive for beginners, and should give a 'jumping off' point for more advanced students and researchers.
Those who find the book valuable should thank Mr T.R. Graham of the (then) Her Majesty's Inspectorate of Pollution. Without his contract, Iwho had seen other wetlands but properly studied only East Anglia and reedswould not have realised there was no such book. I wanted it for that contract! So, several years later, here it is, for others who also want, in one book, a holistic view, and later than Tansley (1939).
All readers of this book probably know wetlands are a threatened habitat, but most probably do not know how little is being done to meet that threat. There is more lip-service than for, say, chalk grasslands, but where is the actual service? Barely half a dozen publishing on British conservation research; a score or two on any British wetland research; money for stopping abstraction, reversing drainage, preventing pollution and necessary management is noticeable by its absence (with few exceptions).
The need is great. Can any reader respond to that need?
