About this book

Integrates principles and management techniques that apply to all grazing lands and to all grazing animals. This new edition features: Animal nutrition and nutritional balance when fed on different sorts of grazing lands; Seasonal variation and limits placed on ecosystems by grazing; The effects of grazing on grazing lands; The various sorts of grazing behaviours; and Selecting plants and managing grazing lands.

The well-indexed an important source of information and references for a diverse range of readers, serving us both a textbook and a reference manual. As such it will appeal to lecturers and advanced students; also advisers, consultants and innovative rangeland managers will benefit from dipping into the text. Researchers will find the book a valuable resource for the cited references... - EAAP News
