This volume explores the South Brazilian grasslands, a unique complex of ecosystems in Brazil. Despite high biodiversity and many important ecosystem services, their biodiversity and conservation are neglected, both nationally, and globally. This book provides a state-of-the-art synthesis of knowledge on the biodiversity and its drivers in South Brazilian grasslands and associated ecosystems. Further, the book discusses conservation challenges and options, as well as management strategies that help to maintain the region's uniqueness. The chapters present information on biodiversity and ecological features of the region, and put this information into the context of historical and current human land uses, allowing for links to global discussions of conservation and sustainable development. Altogether, the book contains 20 chapters organized in four sections. The book is directed at researchers, students and professionals working with biodiversity and sustainable development in southern Brazil, as well as to the international scientific and conservation community interested in grasslands and associated ecosystems, particularly in tropical and subtropical regions.
