An analysis of trees in New York City reveals that this city has about 5.2 million trees with canopies that cover 20.9 percent of the area. The most common tree species are tree of heaven, black cherry, and sweetgum. The urban forest currently stores about 1.35 million tons of carbon valued at $24.9 million. In addition, these trees remove about 42,300 tons of carbon per year ($779,000 per year) and about 2,202 tons of air pollution per year ($10.6 million per year). The structural, or compensatory, value is estimated at $5.2 billion. Information on the structure and functions of the urban forest can be used to improve and augment support for urban forest management programs and to integrate urban forests within plans to improve environmental quality in the New York City area.

The Chicago metropolitan area is home to far more protected nature than most people realize. There's a critical factor of the Chicago Wilderness restoration effort that makes it unique. A grassroots volunteer community, thousands strong, works alongside agency staff to give nearby nature what it needs to thrive in an everchanging urban context. A Healthy Nature Handbook captures hard-earned ecological wisdom from this community in engaging and highly readable chapters, each including illustrated restoration sequences.

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.

Meeting today’s environmental challenges requires a new way of thinking about the intricate dependencies between humans and nature. Ecology and Ecosystem Conservation provides students and other readers with a basic understanding of the fundamental principles of ecological science and their applications, offering an essential overview of the way ecology can be used to devise strategies to conserve the health and functioning of ecosystems. The book begins by exploring the need for ecological science in understanding current environmental issues and briefly discussing what ecology is and isn’t. Subsequent chapters address critical issues in conservation and show how ecological science can be applied to them. The book explores questions such as: • What is the role of ecological science in decision making? • What factors govern the assembly of ecosystems and determine their response to various stressors? • How does Earth’s climate system function and determine the distribution of life on Earth? • What factors control the size of populations? • How does fragmentation of the landscape affect the persistence of species on the landscape? • How does biological diversity influence ecosystem processes? The book closes with a final chapter that addresses the need not only to understand ecological science, but to put that science into an ecosystem conservation ethics perspective.

The Law and Policy of Ecosystem Services is the first comprehensive exploration of the status and future of natural capital and ecosystem services in American law and policy. The book develops a framework for thinking about ecosystem services across their ecologic, geographic, economic, social, and legal dimensions and evaluates the prospects of crafting a legal infrastructure that can help build an ecosystem service economy that is as robust as existing economies for manufactured goods, natural resource commodities, and human-provided services. The book examines the geographic, ecological, and economic context of ecosystem services and provides a baseline of the current status of ecosystem services in law and society. It identifies shortcomings of current law and policy and the critical areas for improvement and forges an approach for the design of new law and policy for ecosystem services. Included are a series of nine empirical case studies that explore the problems caused by society’s failure to properly value natural capital. Among the case study topics considered are water issues, The Conservation Reserve Program, the National Conservation Buffer Initiative, the agricultural policy of the European Union, wetland mitigation, and pollution trading. The Law and Policy of Ecosystem Services is a groundbreaking look at the question of whether and how law and policy can shape a sustainable system of ecosystem service management. It is an accessible and informative work for faculty, students, and policy makers concerned with ecology, economics, geography, political science, environmental studies, law, and related fields.

Restoration plans must take into account the needs of current or desired wildlife species in project areas. Restoring Wildlife gives ecologists, restorationists, administrators, and other professionals involved with restoration projects the tools they need to understand essential ecological concepts, helping them to design restoration projects that can improve conditions for native species of wildlife. It also offers specific guidance and examples on how various projects have been designed and implemented. The book interweaves theoretical and practical aspects of wildlife biology that are directly applicable to the restoration and conservation of animals. It provides an understanding of the fundamentals of wildlife populations and wildlife-habitat relationships as it explores the concept of habitat, its historic development, components, spatialtemporal relationships, and role in land management. It applies these concepts in developing practical tools for professionals. Restoring Wildlife builds on the foundation of material presented in Wildlife Restoration, published by Island Press in 2002, offering the basic information from that book along with much updated material in a reorganized and expanded format. Restoring Wildlife is the only single source that deals with wildlife and restoration, and is an important resource for practicing restorationists and biologists as well as undergraduate and graduate students in wildlife management, ecological restoration, environmental science, and related fields.

The central concept guiding the management of parks and wilderness over the past century has been “naturalness”—to a large extent the explicit purpose in establishing these special areas was to keep them in their “natural” state. But what does that mean, particularly as the effects of stressors such as habitat fragmentation, altered disturbance regimes, pollution, invasive species, and climate change become both more pronounced and more pervasive? Beyond Naturalness brings together leading scientists and policymakers to explore the concept of naturalness, its varied meanings, and the extent to which it provides adequate guidance regarding where, when, and how managers should intervene in ecosystem processes to protect park and wilderness values. The main conclusion is the idea that naturalness will continue to provide an important touchstone for protected area conservation, but that more specific goals and objectives are needed to guide stewardship. The issues considered in Beyond Naturalness are central not just to conservation of parks, but to many areas of ecological thinking—including the fields of conservation biology and ecological restoration—and represent the cutting edge of discussions of both values and practice in the twenty-first century. This bookoffers excellent writing and focus, along with remarkable clarity of thought on some of the difficult questions being raised in light of new and changing stressors such as global environmental climate change.
