The collected papers from the Dynamic Landscape Restoration seminar is aimed at all those involved in the conservation and restoration of sites and landscapes, be they degraded post-industrial environments, damaged historic parklands, urban greenspace or agricultural areas. Speakers and participants at the event included landscape professionals, archaeologists, ecologists, earth scientists, planners, conservationists and those in education.
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.
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 194. Stream Restoration in Dynamic Fluvial Systems: Scientific Approaches, Analyses, and Tools brings together leading contributors in stream restoration science to provide comprehensive consideration of process-based approaches, tools, and applications of techniques useful for the implementation of sustainable restoration strategies. Stream restoration is a catchall term for modifications to streams and adjacent riparian zones undertaken to improve geomorphic and/or ecologic function, structure, and integrity of river corridors, and it has become a multibillion dollar industry. A vigorous debate currently exists in research and professional communities regarding the approaches, applications, and tools most effective in designing, implementing, and assessing stream restoration strategies given a multitude of goals, objectives, stakeholders, and boundary conditions. More importantly, stream restoration as a research-oriented academic discipline is, at present, lagging stream restoration as a rapidly evolving, practitioner-centric endeavor. The volume addresses these main areas: concepts in stream restoration, river mechanics and the use of hydraulic structures, modeling in restoration design, ecology, ecologic indices, and habitat, geomorphic approaches to stream and watershed management, and sediment considerations in stream restoration. Stream Restoration in Dynamic Fluvial Systems will appeal to scholars, professionals, and government agency and institute researchers involved in examining river flow processes, river channel changes and improvements, watershed processes, and landscape systematics.
We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.
This book provides an introduction to a fairly new approach to natural resources management practice entitled ecohydrology-based landscape restoration. Ecohydrology-based landscape restoration integrates landscape restoration practices with ecohydrology science and principles in order to help address the limitations of current management practices in developing countries. Focusing on both the theory and practice of implementing new management practices, the book includes conceptual designs and practical demonstrations for a variety of sites, including hillsides, farmlands, gullies, riparian buffers and wetlands, while also drawing on field research conducted in Ethiopia. The book puts forward principles for improving current practices, which include the better integration of hydrological and ecological concerns, the greater involvement of local communities, the adoption of indigenous practices, the establishment of green and semi-grey infrastructure as an ecohydrological systemic solution and the necessity of taking an adaptive approach to managing landscapes. This book will be of great interest to students and scholars of water resource management, ecohydrology and landscape restoration as well as professionals involved in the restoration of landscapes in developing countries.
Restoration ecology, as a scientific discipline, developed from practitioners’ efforts to restore degraded land, with interest also coming from applied ecologists attracted by the potential for restoration projects to apply and/or test developing theories on ecosystem development. Since then, forest landscape restoration (FLR) has emerged as a practical approach to forest restoration particularly in developing countries, where an approach which is both large-scale and focuses on meeting human needs is required. Yet despite increased investigation into both the biological and social aspects of FLR, there has so far been little success in systematically integrating these two complementary strands. Bringing experts in landscape studies, natural resource management and forest restoration, together with those experienced in conflict management, environmental economics and urban studies, this book bridges that gap to define the nature and potential of FLR as a truly multidisciplinary approach to a global environmental problem. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.
This book is the product of the 2nd World Conference on Environmental History, held in Guimarães, Portugal, in 2014. It gathers works by authors from the five continents, addressing concerns raised by past events so as to provide information to help manage the present and the future. It reveals how our cultural background and examples of past territorial intervention can help to combat political and cultural limitations through the common language of environmental benefits without disguising harmful past human interventions. Considering that political ideologies such as socialism and capitalism, as well as religion, fail to offer global paradigms for common ground, an environmentally positive discourse instead of an ecological determinism might serve as an umbrella common language to overcome blocking factors, real or invented, and avoid repeating ecological loss. Therefore, agency, environmental speech and historical research are urgently needed in order to sustain environmental paradigms and overcome political, cultural an economic interests in the public arena. This book intertwines reflections on our bonds with landscapes, processes of natural and scientific transfer across the globe, the changing of ecosystems, the way in which scientific knowledge has historically both accelerated destruction and allowed a better distribution of vital resources or as it, in today’s world, can offer alternatives that avoid harming those same vital natural resources: water, soil and air. In addition, it shows the relevance of cultural factors both in the taming of nature in favor of human comfort and in the role of the environment matters in the forging of cultural identities, which cannot be detached from technical intervention in the world. In short, the book firstly studies the past, approaching it as a data set of how the environment has shaped culture, secondly seeks to understand the present, and thirdly assesses future perspectives: what to keep, what to change, and what to dream anew, considering that conventional solutions have not sufficed to protect life on our planet.
Ecological restoration, although a relatively new endeavour compared to other disciplines, has gained significant momentum during the last decade as accelerating global change becomes more apparent. It is now widely accepted by the scientific community that to avoid further devastating effects of climate change and biodiversity loss, humanity must determinedly move more to protect and restore natural ecosystems. Many restoration efforts of the past have been ad hoc, site and situation-specific and have often failed to achieve desired outcomes, but over the last decade, many countries are allocating increasingly significant amounts of financial investment towards restoration with the goal of achieving more systematic and predictable outcomes. Today, activities related to restoring ecosystems, natural assets and biodiversity are a global focus. This book covers a wide range of topics related to ecological restoration including for grasslands, wetlands, temperate and tropical forests and arid zones. Importantly, it also focuses on ecological restoration in human-disturbed landscapes such as for urban areas, farmlands, mine sites and transport corridors. It highlights the necessity for evidence-based approaches that are both nuanced and complementary with prescriptions for people-based restoration, that is socially inclusive and cognisant of historic and current community sentiment. Ambitious landscape and continental scale targets for ecological restoration have been set across the globe. However, without practical guidelines developed from restoration evaluations from the recent past to follow, future efforts are unlikely to be successful, nor -expected targets met. To that end, this book reviews and highlights a large number and variety of restoration stories from around the world. Most are presented as reader-friendly case studies, that feature innovative and systematic techniques for undertaking species-rich ecological restoration. Together they provide inspiration for current and future professionals and offer unique glimpses into state-of-the-art practice for this critically important discipline
This document is a cooperative effort among fifteen Federal agencies and partners to produce a common reference on stream corridor restoration. It responds to a growing national and international interest in restoring stream corridors.
Rivers are vital ecosystems that support aquatic and terrestrial biodiversity and several ecosystem services, including food, water, culture, and recreation. After centuries of building dams on rivers across the world, dam removal projects are now on the rise due to obsolescence, reservoir sedimentation, insufficient return on investment, or river restoration and conservation priorities. Most dam removal projects have focused on smaller structures (< 10 m in structural height), but larger structures have also started to be removed in increasing numbers as practitioners, river managers, conservationists, and the public have gained more experience with the practice. Recent estimates suggest that only a small fraction of dam removals have been scientifically studied, and include mostly small dams and short time scales. Documenting the long-term ecological outcomes of large dam removal (i.e. >10 m tall) represents a new frontier in dam removal research: projects are more recent and provide an opportunity to understand the complex ecological changes that occur with these transformative restoration projects. Here, we aim to collate a diverse array of papers on long-term dam removal research projects involving larger dams (>10 m) to synthesize the issues, outcomes, tools, and experimental designs used to study large dam removal projects from physical, biological, and ecological perspectives. With this collection, we aim to showcase diverse global projects on ecosystem responses to large dam removal; collect perspectives from different disciplines, fields, and geographies; and synthesize the current state of knowledge in this area. We expect that this Research Topic will be informative to ongoing, long-term ecological restoration and monitoring projects related to dam removal as well as to upcoming large dam removal projects. We welcome contributions from all disciplines addressing the physical, ecological, and ecosystem responses to large-scale dam removal. Contributions could include original research in a specific discipline or area, case studies, or synthesis papers that address one or more of these topics in a transdisciplinary approach. Contributors could address any of the following major topics as related to outcomes of large dam removal, alone or in combination: Freshwater, estuarine, and marine aquatic biota; River and reservoir geomorphology; Terrestrial and riparian vegetation; Wildlife; Sedimentation; and Modelling. We would like contributors to highlight key results in their area of study, cross-disciplinary insights, and lessons learned that could inform ongoing monitoring and research efforts in current projects as well as upcoming large dam removals.
