During the nineteenth century, ivory hunting caused asubstantial decrease of elephant numbers in southern Africa. Soonafter that, populations of many other large and medium-sizedherbivores went into steep decline due to the rinderpest pandemicin the 1890s. These two events provided an opportunity for woodlandestablishment in areas previously intensively utilized by elephantsand other herbivores. The return of elephants to currentlyprotected areas of their former range has greatly influencedvegetation locally and the resulting potential negative effects onbiodiversity are causing concern among stakeholders, managers, andscientists.
This book focuses on the ecological effects of the increasingelephant population in northern Botswana, presenting the importanceof the elephants for the heterogeneity of the system, and showingthat elephant ecology involves much wider spatiotemporal scalesthan was previously thought. Drawing on the results of theirresearch, the authors discuss elephant-caused effects on vegetationin nutrient-rich and nutrient-poor savannas, and the potentialcompetition between elephants on the one hand and browsers andmixed feeders on the other.
Ultimately this text provides a comprehensive review ofecological processes in African savannas, covering long-termecosystem changes and human-wildlife conflicts. It summarises newknowledge on the ecology of the sub-humid African savannaecosystems to advance the general functional understanding ofsavanna ecosystems across moisture and nutrient gradients.

Christina Skarpe is a Professor in Applied Ecology at theFaculty of Applied Ecology and Agricultural Sciences at HedmarkUniversity College, Norway. Her main research interest is largeherbivores and African savanna ecology. From Uppsala University,Sweden, Botswana Ministry of Agriculture and later from NorwegianInstitute of Nature Research and Hedmark University College sheconcentrated on herbivores- and worked on diverse projects inAfrica, Scandinavia, China and Central America.
Johan du Toit is Professor of Ecology and Conservation ofLarge Mammals in the Wildland Resources Department at Utah StateUniversity, USA. He has almost 30 years' experienceconducting ecological research in African savanna ecosystems. Atthe University of Zimbabwe he coordinated the Tropical ResourceEcology Programme, after which he was the Austin Roberts Professorof Mammalogy and Director of the Mammal Research Institute at theUniversity of Pretoria. His research focus is the ecology andconservation of large mammals in terrestrial ecosystems.
Stein R. Moe is a Professor of Ecology at the NorwegianUniversity of Life Sciences, Norway. Although his scientific worksspan over four continents, his main focus has been on Africansavanna ecology. He is currently coordinating a Master'sprogram in tropical ecology and natural resource management in theDepartment of Ecology and Natural Resource Management. Followingseveral years as a departmental board member, he is now a member ofthe faculty board at the University. - Newsletter
