Grazing management is one of the most important management activities world-wide, and it has been a traditional sustainable land use in many areas of the planet. This book demonstrates the poor extrapolation capacity that grazing studies have due to site-dependent effects and sensitivity to changes in weather conditions and soil characteristics. Therefore, researchers should be cautious when suggesting management recommendations, such as removing all grazing animals or reducing grazing activities. A highly variable ecological force such as grazing, with important environmental and social implications, should be analysed deeply before extrapolated results or suggesting management practices.
