Elephants are among the most magnificent – but also most problematic –members of South Africa's wildlife population. While they are sought after by South African and foreign tourists alike, they also have a major impact on their environment. As a result, elephant management has become a highly complex and often controversial discipline. The information needed to underpin vital decisions about elephant management has largely been unavailable to decision-makers, contested by experts, or simply unknown. As a result, the South African Minister for Environmental Affairs and Tourism convened a round table to advise him on this issue. The round table recommended that a scientific assessment of elephant management be undertaken to gather, evaluate, and present all the relevant information on this topic. Its main findings and recommendations are contained in this volume. Elephant Management is the first book of its kind, combining the work of more than 60 national and international experts. Extensively reviewed by policy-makers and other stakeholders, it is the most systematic and comprehensive review of savanna elephant populations and factors relevant to managing them to date. As such it is of interest to a broad spectrum of readers in South Africa and elsewhere. Above all, it is aimed at helping conservation policy-makers and practitioners to choose the best possible options for the sustainable preservation of these iconic animals.

This volume is the result of a Symposium, held in October, 1985, to celebrate the Silver Jubilee of the De partment of Plant Ecology of the University of Groningen. The Department of Plant Ecology was founded by Professor Dingeman Bakker and has, since its incep tion, been involved with studies of grasslands, and especially with the effects of human interference on grassland communities. It has been especially involved in an almost unique enterprise to convert areas of grassland from intensive agricultural production to nature reserves. With over-production of most food commodities in the EEC, and increasing interest in various types of 'set aside' schemes, this initiative now seems to be remarkably prescient. The Netherlands have a long history of human manipulation of the environment. Indeed, the Dutch en vironment is probably more man-made than that of any other country. In view of this, and the Laborato ry's interest in managed grasslands, it is not surprising that 'Disturbance in Grasslands' was selected as the topic for the Laboratory's Jubilee Symposium. Although both the Symposium and the resulting vo lume, have a strong Dutch component, the organisers invited a number of contributors from Europe and elsewhere to provide key chapters. The result is a volume which covers many aspects of disturbance in a variety of grasslands. Disturbance is considered at both the community and the population level, and the principles and processes underlying those responses are explored.

Silvology is the general science of forest ecosystems, without the usual division between Man and Nature. This systematic treatment of forests intends to integrate and harmonize existing approaches with the help of systems modeling in a hierarchy of close system levels, according to criteria of biological architecture, biomass production and species composition. Scientists and practitioners will appreciate this synoptic treatment of forests and their ecology, allowing the balance of holistic and reductionist viewpoints, and the placement of phenomena and techniques. Topics covered include: - introduction of the methods, - sections on forest organisms, - a special chapter on trees, - eco-units, i.e. forest ecosystems developing after some zero-event like fire, storm or waterlogging, - silvatic mosaics built by the eco-units of different size, architecture and species composition, - a summary of silvological rules determining system's behaviour at every level, e.g. fragmentation and fusion, transfer of functions, irreversibility and process oscillation.

Saving endangered species presents a critical and increasingly pressing challenge for conservation and sustainability movements, and is also matter of survival and livelihoods for the world's poorest and vulnerable communities. In 1973, a global Convention on International Trade in Endangered Species (CITES) was adopted to stem the extinction of many species. In 2015, as part of the Sustainable Development Goals (SDG 15) the United Nations called for urgent action to protect endangered species and their natural habitats. This volume focuses on the legal implementation of CITES to achieve the global SDGs. Activating interdisciplinary analysis and case studies across jurisdictions, the contributors analyse the potential for CITES to promote more sustainable development, proposing international and national regulatory innovations for implementing CITES. They consider recent innovations and key intervention points along flora and fauna value chains, advancing coherent recommendations to strengthen CITES implementation, including through the regulation of trade in endangered species globally and locally.

This book provides a quantitative analysis of the role of woody plants in semi-arid regions, for the aSSessment of their benefits in agrosylvopastoralland-use systems with productive and sus tainability objectives. The insights presented and conclusions drawn allow the additional benefits of woody plants for specific climatic and physical site conditions and land-use systems to be estimated. The Sahel and Sudan zones in West Africa, on which the book focusses, represent resource-poor conditions, whose ecological dynamics have been relatively well studied. The role of woody plants in this region, as assessed in this book, is extrapolated to other semi-arid regions, leading to general conclusions on agroforestry's potential as an option for sustainable land use in semi-arid regions. The origins of this book go back to 1982, when the Club du Sahel requested that available data on woody plants in the Sahel region be synthesised, to provide basic information to enable better attention to be given to woody plants in rural development programmes. We are grateful to the Club du Sahel for this challenge. Various people contributed to studies used in this book. The preliminary inventory of the data available was made by Frits Ohler; later his work was continued by Franciska Dekker.

This volume is the fifth in a series of publications produced over the last five years on the ecology of tropical savannas. The volumes arise from work undertaken by the Responses of Savannas to Stress and Disturbance (RSSD) Program, under the auspices of the International Union of Biological Sciences (IUBS) Decade of the Tropics Programme, co-sponsored by the UNESCO Man and the Biosphere (MAB) Program. Savannas cover just under one third of the world's land surface and contain a large and rapidly growing proportion of the world's population as well as the majority of its rangelands and livestock. Most savannas are experiencing increasing pressures from demographic and economic changes that have increased dramatically over the past few decades. In addition to the changing patterns in demography and economics, and the forecasts of global warming further alert us to the most important challenge - to conserve and manage wisely the savanna ecosystems of the world. It is this conservation that forms the basis of the work of the RSSD Program. This fifth publication is comprised of research papers presented at the RSSD's international symposium held in Darwin, Australia, in 1988. The papers address the Australian perspective and intercontinental comparisons and come from an international, expert authorship.

Grazing animals enjoy an ambiguous reputation in the field of nature conservation. Livestock are often treated as a scourge, yet native large herbivores form the prime attraction of many a reserve. This book gives the first comprehensive overview of the use of grazing as a tool in conservation management. Considering in turn the ecological and historical background, the impact of grazing on community structure, management applications and future prospects, this book examines issues such as the role of herbivores as keystone species, the assessment of habitat quality and the function of scientific models in advancing grazing management. Large herbivores are shown to be potentially powerful allies in the management of nature reserves, particularly in the maintenance, enhancement or restoration of biodiversity. Grazing and Conservation Management will appeal to conservation biologists and rangeland managers, providing them with a clearer understanding of grazing and conservation management.

Understanding deserts and drylands is essential, as arid landscapes cover >40% of the Earth and are home to two billion people. Today's problematic environment–human interaction needs contemporary knowledge to address dryland complexity. Physical dimensions in arid zones—land systems, climate and hazards, ecology—are linked with social processes that directly impact drylands, such as land management, livelihoods, and development. The challenges require integrated research that identifies systemic drivers across global arid regions. Measurement and monitoring, field investigation, remote sensing, and data analysis are effective tools to investigate natural dynamics. Equally, inquiry into how policy and practice affect landscape sustainability is key to mitigating detrimental activity in deserts. Relations between socio-economic forces and degradation, agro-pastoral rangeland use, drought and disaster and resource extraction reflect land interactions. Contemporary themes of food security, conflict, and conservation are interlinked in arid environments. This book unifies desert science, arid environments, and dryland development. The chapters identify land dynamics, address system risks and delineate human functions through original research in arid zones. Mixed methodologies highlight the vital links between social and environmental science in global deserts. The book engages with today's topical themes and presents novel analyses of arid land systems and societies.

This book tells the sweeping story of the role that East African savannas played in human evolution, how people, livestock, and wildlife interact in the region today, and how these relationships might shift as the climate warms, the world globalizes, and human populations grow. Our ancient human ancestors were nurtured by African savannas, which today support pastoral peoples and the last remnants of great Pleistocene herds of large mammals. Why has this wildlife thrived best where they live side-by-side with humans? Ecologist Robin S. Reid delves into the evidence to find that herding is often compatible with wildlife, and that pastoral land use sometimes enriches savanna landscapes and encourages biodiversity. Her balanced, scientific, and accessible examination of the current state of the relationships among the region’s wildlife and people holds critical lessons for the future of conservation around the world.

In view of the rapidly changing ecology of Africa ,this work provides benchmarks for some of the major, and more neglected, aspects, with an accent on historical data to enable habitats to be seen in relation to their previous state, forming a background reference work to understanding how the ecology of Africa has been shaped by its past. Reviewing historical data wherever possible it adopts an holistic view treating man as well as animals, with accent on diseases both human and animal which have been a potent force in shaping Africa’s ecology, a role neglected in ecological studies.
