Section 1 of this Field Guide considers the need to manage deer. Section 2 gives guidance on choosing a suitable census and sampling method. Section 3 presents 21 methods of population estimation, with a worked example provided in most cases. Methods of the greatest potential use to practising deer managers (in terms of time and cost-effectiveness) are described in more detail. Section 4 reinforces the advantages of using census data in the development of effective deer management strategies. Section 5 comprises eleven appendices of useful supporting information. Deer populations in Britain are increasing; this book is a timely and practical guide for woodland managers and wildlife rangers. This publication is still available in hard copy.
