Social historians will look back on the 1980s as a period when a global consciousness of the environment developed. Stimulated by major issues and events such as oil and chemical spills, clearing of rainforests, pollu tion of waterways, and, towards the end of the decade, concern over the greenhouse effect, concern for the environment has become a major social and political force. Unfortunately, the state of the environment and its future manage ment are still very divisive issues. Often, at a local level, concern for the environment is the antithesis of development. The debate usually focusses on the possible negative environmental impacts of an activity versus the expected positive economic impacts. It is a very difficult task to integrate development and conservation, yet it is towards this objec tive that the sustainable development debate is moving. The issues in the central wheatbelt of Western Australia are typical of the environment versus development debate. It is undoubted that the development of the area, which involved clearing the native vegetation, has had a major impact upon the original ecosystems. Many of the natural habitats are threatened and local extinction of flora and fauna species is a continuing process. Moreover, there are clear signs that land degradation processes such as dryland salinity are depleting the land resource.

Towards Sustainable Production and Nature Conservation

Reintegrating Fragmented Landscapes

Helen E. Allison

This book was first published in 2006. Despite many well-intentioned policies and changes to management practices, the world's natural resources continue to decline. The roles and interplay between science and policy in the regional broadacre agriculture landscape are examined here, offering readers a thorough understanding of the complex interactions that occur across spatial scales to produce the regional-scale impacts. The fundamental causes of resource degradation, social decline and environmental pollution are addressed, examining the cross-scale drivers from the individual farm level to the global level of commodity systems. Broadacre agriculture is a common land use throughout all continents of the world and is driven by the same type of dynamics, and this case study of the Western Australia agricultural region can be used to clearly demonstrate the principles for other agricultural systems. Aimed at academics, ranging from researchers through to policy analysts, this book will inspire innovation and action in sustainable natural resource management.

This innovative book integrates practical information from restoration projects around the world with the latest developments in successional theory. It recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration. It argues that restoration within a successional context will best utilize the lessons from each of these disciplines.

Landscape ecology is a relatively new area of study, which aims to understand the pattern of interaction of biological and cultural communities within a landscape. This book brings together leading figures from the field to provide an up-to-date survey of recent advances, identify key research problems and suggest a future direction for development and expansion of knowledge. Providing in-depth reviews of the principles and methods for understanding landscape patterns and changes, the book illustrates concepts with examples of innovative applications from different parts of the world. Forming a current 'state-of-the-science' for the science of landscape ecology, this book forms an essential reference for graduate students, academics, professionals and practitioners in ecology, environmental science, natural resource management, and landscape planning and design.

Land abandonment is increasing as human influence on the globe intensifies and various ecological, social, and economic factors conspire to force the cessation of agriculture and other forms of land management. The “old fields” that result from abandonment have been the subject of much study, yet few attempts have been made to examine the larger questions raised by old field dynamics. Old Fields brings together leading experts from around the world to synthesize past and current work on old fields, providing an up-to-date perspective on the ecological dynamics of abandoned land. The book gives readers a broad understanding of why agricultural land is abandoned, the factors that determine the ecological recovery of old fields, and how this understanding contributes to theoretical and applied ecology. Twelve case studies from diverse geographical and climatic areas—including Australian rainforest, Brazilian Amazonia, New Jersey piedmont, and South African renosterveld—offer a global perspective on the causes and results of land abandonment. Concluding chapters consider the similarities and differences among the case studies, examine them in the context of ecological concepts, and discuss their relevance to the growing field of restoration ecology. Old Fields is the first book to draw together studies on old fields from both a theoretical and practical perspective. It represents an important contribution to the development of theory on old field dynamics and the practice of ecological restoration on abandoned farmland, and the broader implications of old field dynamics to ecology and restoration.

As scientific understanding about ecological processes has grown, the idea that ecosystem dynamics are complex, nonlinear, and often unpredictable has gained prominence. Of particular importance is the idea that rather than following an inevitable progression toward an ultimate endpoint, some ecosystems may occur in a number of states depending on past and present ecological conditions. The emerging idea of “restoration thresholds” also enables scientists to recognize when ecological systems are likely to recover on their own and when active restoration efforts are needed. Conceptual models based on alternative stable states and restoration thresholds can help inform restoration efforts. New Models for Ecosystem Dynamics and Restoration brings together leading experts from around the world to explore how conceptual models of ecosystem dynamics can be applied to the recovery of degraded systems and how recent advances in our understanding of ecosystem and landscape dynamics can be translated into conceptual and practical frameworks for restoration. In the first part of the book, background chapters present and discuss the basic concepts and models and explore the implications of new scientific research on restoration practice. The second part considers the dynamics and restoration of different ecosystems, ranging from arid lands to grasslands, woodlands, and savannahs, to forests and wetlands, to production landscapes. A summary chapter by the editors discusses the implications of theory and practice of the ideas described in preceding chapters. New Models for Ecosystem Dynamics and Restoration aims to widen the scope and increase the application of threshold models by critiquing their application in a wide range of ecosystem types. It will also help scientists and restorationists correctly diagnose ecosystem damage, identify restoration thresholds, and develop corrective methodologies that can overcome such thresholds.

Land conversion, climate change and species invasions arecontributing to the widespread emergence of novel ecosystems, whichdemand a shift in how we think about traditional approaches toconservation, restoration and environmental management. They arenovel because they exist without historical precedents and areself-sustaining. Traditional approaches emphasizing native speciesand historical continuity are challenged by novel ecosystems thatdeliver critical ecosystems services or are simply immune topractical restorative efforts. Some fear that, by raising the issueof novel ecosystems, we are simply paving the way for a morelaissez-faire attitude to conservation and restoration.Regardless of the range of views and perceptions about novelecosystems, their existence is becoming ever more obvious andprevalent in today’s rapidly changing world. In this firstcomprehensive volume to look at the ecological, social, cultural,ethical and policy dimensions of novel ecosystems, the authorsargue these altered systems are overdue for careful analysis andthat we need to figure out how to intervene in them responsibly.This book brings together researchers from a range of disciplinestogether with practitioners and policy makers to explore thequestions surrounding novel ecosystems. It includes chapters on keyconcepts and methodologies for deciding when and how to intervenein systems, as well as a rich collection of case studies andperspective pieces. It will be a valuable resource for researchers,managers and policy makers interested in the question of howhumanity manages and restores ecosystems in a rapidly changingworld.

Moving from Perspectives to Principles

Managing and Designing Landscapes for Conservation

Understanding how ecosystems are assembled -- how the species that make up a particular biological community arrive in an area, survive, and interact with other species -- is key to successfully restoring degraded ecosystems. Yet little attention has been paid to the idea of assembly rules in ecological restoration, in both the scientific literature and in on-the-ground restoration efforts. Assembly Rules and Restoration Ecology, edited by Vicky M. Temperton, Richard J. Hobbs, Tim Nuttle, and Stefan Halle, addresses that shortcoming, offering an introduction, overview, and synthesis of the potential role of assembly rules theory in restoration ecology. It brings together information and ideas relating to ecosystem assembly in a restoration context, and includes material from a wide geographic range and a variety of perspectives. Assembly Rules and Restoration Ecology contributes new knowledge and ideas to the subjects of assembly rules and restoration ecology and represents an important summary of the current status of an emerging field. It combines theoretical and practical aspects of restoration, making it a vital compendium of information and ideas for restoration ecologists, professionals, and practitioners.
