Over the past 50 years, major changes have taken place in the distribution of aquatic plants in Europe. Many species have declined whilst other species have increased in abundance or spread, including several that were originally introduced from the New World. Despite the relative richness of the aquatic flora of Britain and Ireland, it is a neglected area of study. This book provides a summary of the distribution, habitat and reproductive biology of 200 taxa in 72 genera, with individual distribution maps, and also summarizes their distribution overseas. Unrevised Brill edition.
