Book Description
The first comprehensive guide to the aquatic plants of the region Beneath the surface of bodies of freshwater—springs, streams, rivers, ponds and lakes—there is a world of plants of great variety and beauty, a realm that is often poorly known and understood. Correctly identified, these plants can tell us much about the character and condition of the habitats in which they live. A collaboration of Danish, German, and British field botanists specializing in freshwater plants, this guide presents all of the known aquatic plants of Northern and Central Europe, including Britain and Ireland, as well as many marginal and wetland species. This is the first comprehensive guide to the identification of the region’s 410 species and hybrids of both native and non-native ferns and flowering plants that are dependent upon freshwater wetlands. Following the latest taxonomy, the book features 358 plates in pen and ink, more than 1,400 colour photographs, illustrated keys, distribution maps and detailed descriptions. The introduction gives an overview of evolution, anatomy and morphology, ecology, eco-physiology, research traditions and more, and the book also includes guidelines for working with aquatic plants. The first comprehensive guide to the region’s aquatic plants Covers all 410 known species Features 358 illustrated plates, more than 1,400 colour photographs, distribution maps, detailed descriptions and much more

Book Description
There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical and physical, and biological and biomanipulation. This series of papers from over 20 different countries was generated from the tenth in the highly successful series of European Weed Research Society symposia on aquatic plant management, this being the tenth. It provides a valuable insight into the complexities involved in managing aquatic systems, discusses state-of-the-art control techniques and deals with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.

Book Description
This is the first book to cover England's rare and threatened mosses and liverworts, collectively known as bryophytes. As a group, they are the most ancient land plants and occupy a unique position in the colonization of the Earth by plant life. However, many are at risk from habitat loss, pollution, climate change, and other factors. Britain is one of the world's best bryologically recorded areas, yet its mosses and liverworts are not well known outside a small band of experts. This has meant that conservation action has tended to lag behind that of more charismatic groups such as birds and mammals. Of the 916 different types of bryophyte in England, 87 are on the British Red List and are regarded as threatened under the strict criteria of the International Union for the Conservation of Nature. This book aims to raise awareness by providing stunning photographs--many never before published--of each threatened species, as well as up-to-date profiles of 84 of them, including status, distribution, history, and conservation measures. The book looks at what bryophytes are, why they are important and useful, and what makes them rare; it also examines threats, extinctions, ex situ conservation techniques, legislation, and the impact of the 1992 Convention on Biological Diversity. Provides the first treatment of England's rare and threatened mosses and liverworts Features stunning photographs--many never before published--of each species and many of their habitats Treats each species in a handy and attractive double-page layout Includes up-to-date profiles of 84 species, including status, distribution, history, and conservation measures Presents the first overview of English bryophyte conservation Offers invaluable guidance to people working in conservation in England, the British Isles, Europe, and beyond
