This is a detailed and useful handbook of for the serious river and pond enthusiast. This book "is intended to be used by conservation volunteers and all others interested in maintaining or improving valuable natural habitats through manual work. By 'waterways' we mean bodies of fresh water: springs, ponds, lakes, streams, rivers, canals and ditches. By 'wetlands' we mean sites which are waterlogged or water-covered for a significant part of the year; swamps, marshes, bogs, fens and wet grasslands. Such categories often overlap. Ponds may be temporary, marshes may flood. Fens may contain open pools, lake shores may be swamp-fringed. In the same way, wetlands grade into damp scrub, heath or moorland. But in every habitat covered by this Handbook you are likely to get your feet wet. Salt and brackish habitats have, however, been excluded." Chapters include: A look at ponds and waterways; Waterway and wetland ecology; Management for conservation and amenity; Waterways, wetlands and the law; Safety, equipment and organisation; New ponds; Artificial linings; Waterway clearance; Bank stabilistation, islands and rafts; Drainage; Dams, weirs and sluices; Vegetation management.
