Damaged Ecosystems And Restoration

Our environment has been greatly damaged due to pollution and over exploitation of natural resources by human beings. All the natural ecosystems have been damaged to a great extent. Restoration of these damages is becoming a priority and of environmental interest. Science and technology of restoration ecology is rapidly evolving. Restoration requires a holistic approach. Restoration technology is now available to redirect the damaged ecosystems to their near natural integrity. In this context, this book is the first of its kind in reviewing the different approaches undertaken to restore various damaged ecosystems. Scientists currently working in this field have contributed their work in the form of reviews, site-specific case studies, technology for bioremediation and biodegradation. The book will provide first hand information in this currently expanding field and will be helpful to biologists, environmental scientists, engineers, wastewater treatment experts, microbiologists and all those interested in the conservation and management of the environment.

What is a natural habitat? Who can define what is natural when species and ecosystems constantly change over time, with or without human intervention? When a polluted river or degraded landscape is restored from its damaged state, what is the appropriate outcome? With climate change now threatening greater disruption to the stability of ecosystems, how should restoration ecologists respond? Ecological Restoration and Environmental Change addresses and challenges some of these issues which question the core values of the science and practice of restoration ecology. It analyzes the paradox arising from the desire to produce ecological restorations that fit within an historical ecological context, produce positive environmental benefits and also result in landscapes with social meaning. Traditionally restorationists often felt that by producing restorations that matched historic ecosystems they were following nature's plans and human agency played only a small part in restoration. But the author shows that in reality the process of restoration has always been defined by human choices. He examines the development of restoration practice, especially in North America, Europe and Australia, in order to describe different models of restoration with respect to balancing ecological benefit and cultural value. He develops ways to balance more actively these differing areas of concern while planning restorations. The book debates in detail how coming global climate change and the development of novel ecosystems will force us to ask new questions about what we mean by good ecological restoration. When the environment is constantly shifting, restoration to maintain biodiversity, local species, and ecosystem functions becomes even more challenging. It is likely that in the future ecological restoration will become a never-ending, continuously evolving process.

The pace, intensity, and scale at which humans have altered our planet in recent decades is unprecedented. We have dramatically transformed landscapes and waterways through agriculture, logging, mining, and fire suppression, with drastic impacts on public health and human well-being. What can we do to counteract and even reverse the worst of these effects? Restore damaged ecosystems. The Primer of Ecological Restoration is a succinct introduction to the theory and practice of ecological restoration as a strategy to conserve biodiversity and ecosystems. In twelve brief chapters, the book introduces readers to the basics of restoration project planning, monitoring, and adaptive management. It explains abiotic factors such as landforms, soil, and hydrology that are the building blocks to successfully recovering microorganism, plant, and animal communities. Additional chapters cover topics such as invasive species and legal and financial considerations. Each chapter concludes with recommended reading and reference lists, and the book can be paired with online resources for teaching. Perfect for introductory classes in ecological restoration or for practitioners seeking constructive guidance for real-world projects, Primer of Ecological Restoration offers accessible, practical information on recent trends in the field.

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.

The field of ecological restoration is a rapidly growing discipline that encompasses a wide range of activities and brings together practitioners and theoreticians from a variety of backgrounds and perspectives, ranging from volunteer backyard restorationists to highly trained academic scientists and professional consultants. Ecological Restoration offers for the first time a unified vision of ecological restoration as a field of study, one that clearly states the discipline’s precepts and emphasizes issues of importance to those involved at all levels. In a lively, personal fashion, the authors discuss scientific and practical aspects of the field as well as the human needs and values that motivate practitioners. The book: -identifies fundamental concepts upon which restoration is based -considers the principles of restoration practice -explores the diverse values that are fulfilled with the restoration of ecosystems -reviews the structure of restoration practice, including the various contexts for restoration work, the professional development of its practitioners, and the relationships of restoration with allied fields and activities A unique feature of the book is the inclusion of eight “virtual field trips,” short photo essays of project sites around the world that illustrate various points made in the book and are “led” by those who were intimately involved with the project described. Throughout, ecological restoration is conceived as a holistic endeavor, one that addresses issues of ecological degradation, biodiversity loss, and sustainability science simultaneously, and draws upon cultural resources and local skills and knowledge in restoration work.
