Pastures are lands with vegetation cover used for grazing of livestock as part of a farm, or in ranching or other unenclosed pastoral systems or used by wild animals for grazing or browsing. Pasture growth can consist of grasses, legumes, other forbs, shrubs or a mixture. Soil type, minimum annual temperature, and rainfall are important factors in pasture management. This book presents current research data in the study of pastures, including rainforest regeneration in abandoned pastures of Southeast Mexico; pastures in temperate climate zones and the U.S. western Gulf Coast region; a discussion of the dynamic value of pasture phases in intensive agriculture and the restorative capacity of pastures; and, the wet pastures of the Moroccan mountains and the management of pasture phases in Western Australia.
