Ecological restoration is a rapidly evolving discipline that is engaged with developing both methodologies and strategies for repairing damaged and polluted ecosystems and environments. During the last decade the rapid pace of climate change coupled with continuing habitat destruction and the spread of non-native species to new habitats has forced restoration ecologists to re-evaluate their goals and the methods they use. This comprehensive handbook brings together an internationally respected group of established and rising experts in the field. The book begins with a description of current practices and the state of knowledge in particular areas of restoration, and then identifies new directions that will help the field achieve increasing levels of future success. Part I provides basic background about ecological and environmental restoration. Part II systematically reviews restoration in key ecosystem types located throughout the world. In Part III, management and policy issues are examined in detail, offering the first comprehensive treatment of policy relevance in the field, while Part IV looks to the future. Ultimately, good ecological restoration depends upon a combination of good science, policy, planning and outreach – all issues that are addressed in this unrivalled volume.

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.

Tropical island species and ecosystems are threatened worldwide asa result of increasing human pressure. Yet some of theseislands also lend themselves to restoration, as they are physicallydefined units that can be given focused attention, as long asresources are available and clear conservation targets areset. Cousine Island, Seychelles, is a tropical island thathas received such intensive restoration. From a highlydegraded island in the 1960s, the island has now been restored towhat is believed to be a semblance of the natural state. Allalien vertebrates have been eradicated, as have 25 invasive alienplants. Cultivated plants are now confined to one smallsection of the island. Poaching of nesting marine turtles hasbeen stopped, leading to an increase in turtle breedingnumbers. The shearwater population has increased in size withpoaching activities under control. The Sooty tern has alsoreturned to the island to breed. The coastal plateau has beenrestored with over 2500 indigenous shrubs and trees, which have nowgrown into a forest carpet. There are strict quarantine procedureson the island, keeping it free of rats, mice, various alieninvertebrates and potentially invasive alien plants. Threethreatened Seychelles endemic land birds (Seychelles warbler,Seychelles magpie robin and Seychelles white-eye) have beenintroduced and are thriving, with these introductions contributingto both the magpie robin and the white-eye being downgraded from CRto EN (the warbler remains at VU). Ecotourism, and natureconservation for the local inhabitants, have been introduced in away that does not reduce the improved compositional, structural andfunctional biodiversity of the island. The result of therestoration effort appears to be sustainable in the long term,although challenges still remain, especially with regards toadequate clean water and a non-polluting power supply on theisland. Cousine is thus paving the way in the art and scienceof tropical island restoration as a legacy for future generations. There is no other book available on this case study. Theneed for the book arises from the fact that here is a positive notefor conservation in these times of so much negative news on thestate of our environment. More importantly, the book showshow such restoration should be done, and is therefore a model formany other islands around the world. The book has manyillustrations so as to give the book wide appeal and literally toshow what can done in terms of restoration. All this is basedon much scientific detail, including many new data. The aimis, by way of example, to demonstrate how practical restoration,based on sound scientific research, can be carried out for thebetterment of ecological integrity and ecosystem health.

Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.
