Book Description
The first book to look at wilderness in the northeastern US, Wilderness Comes Home features a new approach based on ecological reserve design to protect biological diversity, rewilding and restoring lands to wilderness, and embedding wilderness in a landscape of sustainably managed farmland and forestland. It addresses major theoretical and practical aspects of this important issue -- whether, why, and how to reestablish wilderness areas in the Northeast. Although Western wilderness models already exist for undeveloped areas, Eastern models are still evolving. Protection and social management are being urged not for the "forest primeval" but for recovering areas, in which returning species such as moose and peregrine falcons roam over new growth softwoods and hardwoods, interspersed with the stone walls that once marked field boundaries.

Book Description
This book examines the application of fish community characteristics to evaluate the sustainability and biological integrity of freshwaters. Topics include perspectives on use of fish communities as environmental indicators in program development, collaboration, and partnership forming; influence of specific taxa on assessment of the IBI; regional applications for areas where the IBI had not previously been developed; and specific applications of the IBI developed for coldwater streams, inland lakes, Great Lakes, reservoirs, and tailwaters.

Book Description
This book aims to further advance the field of reintroduction biology beyond the considerable progress made since the formation of the IUCN/SSC Re-introduction Specialist Group. Using an issue-based framework that purposely avoids a structure based on case studies the book's central theme is advocating a strategic approach to reintroduction where all actions are guided by explicit theoretical frameworks based on clearly defined objectives. Issues covered include husbandry and intensive management, monitoring, and genetic and health management. Although taxonomically neutral there is a recognised dominance of bird and mammal studies that reflects the published research in this field. The structure and content are designed for use by people wanting to bridge the research-management gap, such as conservation managers wanting to expand their thinking about reintroduction-related decisions, or researchers who seek to make useful applied contributions to reintroduction.

Book Description
Vertebrate invasive species are important ecologically, socially, and scientifically throughout much of the globe. However, the interdiction and options for management of invasive species are driven by localized regulation at the country or even state level and thus the management of species must be framed within that context. This book is focused around the management of invasive vertebrate species in the United States, although readers will find much of the material broadly applicable to invasive species in other regions. Vertebrate invasive species cause damage to agriculture, property, natural resources, and threaten human health and safety. However, most of these species occur in the United States resulting from human-mediated activities, often being released intentionally. For the first time, the wealth of scientific information about vertebrate invasive species in the United States is summarized and synthesized in a single volume to be easily accessible to ecologists and natural resource managers. With a focus on prominent terrestrial invasive species that have a history of policy and management and highlighting contemporary issues and management, this book consists of 18 chapters written by experts from across the United States. The first section of the book focuses on overarching policy and management topics associated with vertebrate invasive species; including biosecurity threats and risk assessment, policy and regulation, and the economics of their management. The second section provides in-depth reviews of noteworthy invasive mammals, birds, amphibians, and reptiles. After finishing this book, the reader should understand the complexity of managing invasive species, the unique challenges that each new species may present, and the steps forward that may decrease the impact of these species on the environment, human health, and the economy.

Book Description
This book looks at the world's naturalised (successfully introduced) species of bird. Many species have been introduced to countries outside their natural range by people, either deliberately or accidentally, with varied consequences for both those species themselves and the native fauna of their 'new' homes. In Britain, the introduced Canada Goose has quickly become ubiquitous at every lake and riverside, while the Golden Pheasant remains a scarce and unobtrusive inhabitant of a few scattered, remote woodlands. The House Sparrow and Common Starling, both in decline over parts of their native range, are thriving in a naturalised state in North America and elsewhere in the world. Naturalised populations of Mallard in various parts of the world are threatening a total of seven other duck species with extinction through hybridisation. This book discusses each species in turn, describing how, why, when and where its introduction took place, how it became established, and the ecological and economic impacts its presence has had in the country or countries it is naturalised in. Each account has a map, showing natural and introduced range, and there is a wealth of beautiful line drawings of the species concerned.
