An essential guide to assist those surveying for water voles, whether as a professional ecological consultant, a researcher or simply an interested amateur. This book provides detailed descriptions of all the habitats used by water voles, including ideal habitats as well as less typical places, with annotated photos to help the surveyor home in on just the right areas to look. It also contains a comprehensive photographic reference guide to assist in the correct identification of water vole field signs, and explains how to distinguish them from those of similar species. Tips on where and how to search for field signs are also provided, along with guidance on how best to record survey data.
