[null,null,null,"Sommario/riassunto","Over the last two decades the science of range management, like many other resource disciplines, has embraced and integrated environmental concerns in the field, the laboratory, and policy. Rangeland Ecology and Management now brings this integrated approach to the classroom in a thoroughly researched, comprehensive, and readable text. The authors discuss the basics of rangeland management?including grazing and practical management of animals and vegetation?and place those basics within the context of decision making for damaged land, riparian and water conservation, multiple use."]
