This book focuses on urban "green infrastructure" – the interconnected web of vegetated spaces like street trees, parks and peri-urban forests that provide essential ecosystem services in cities. The green infrastructure approach embodies the idea that these services, such as storm-water runoff control, pollutant filtration and amenities for outdoor recreation, are just as vital for a modern city as those provided by any other type of infrastructure. Ensuring that these ecosystem services are indeed delivered in an equitable and sustainable way requires knowledge of the physical attributes of trees and urban green spaces, tools for coping with the complex social and cultural dynamics, and an understanding of how these factors can be integrated in better governance practices. By conveying the findings and recommendations of COST Action FP1204 GreenInUrbs, this volume summarizes the collaborative efforts of researchers and practitioners from across Europe to address these challenges.

“Far-ranging and deeply researched, Urban Forests reveals the beauty and significance of the trees around us.” —Elizabeth Kolbert, Pulitzer Prize-winning author of The Sixth Extinction “Jonnes extols the many contributions that trees make to city life and celebrates the men and women who stood up for America’s city trees over the past two centuries. . . . An authoritative account.” —Gerard Helferich, The Wall Street Journal “We all know that trees can make streets look prettier. But in her new book Urban Forests, Jill Jonnes explains how they make them safer as well.” —Sara Begley, Time Magazine A celebration of urban trees and the Americans—presidents, plant explorers, visionaries, citizen activists, scientists, nurserymen, and tree nerds—whose arboreal passions have shaped and ornamented the nation’s cities, from Jefferson’s day to the present As nature’s largest and longest-lived creations, trees play an extraordinarily important role in our cities; they are living landmarks that define space, cool the air, soothe our psyches, and connect us to nature and our past. Today, four-fifths of Americans live in or near urban areas, surrounded by millions of trees of hundreds of different species. Despite their ubiquity and familiarity, most of us take trees for granted and know little of their fascinating natural history or remarkable civic virtues. Jill Jonnes’s Urban Forests tells the captivating stories of the founding mothers and fathers of urban forestry, in addition to those arboreal advocates presently using the latest technologies to illuminate the value of trees to public health and to our urban infrastructure. The book examines such questions as the character of American urban forests and the effect that tree-rich landscaping might have on commerce, crime, and human well-being. For amateur botanists, urbanists, environmentalists, and policymakers, Urban Forests will be a revelation of one of the greatest, most productive, and most beautiful of our natural resources.

This multidisciplinary book covers all aspects of planning, designing, establishing and managing forests and trees and forests in and near urban areas, with chapters by experts in forestry, horticulture, landscape ecology, landscape architecture and even plant pathology. Beginning with historical and conceptual basics, the coverage includes policy, design, implementation and management of forestry for urban populations.

This title includes a number of Open Access chapters. This new research compendium focuses on urban forestry research and management, while also considering the sociological and community aspects. The book looks at the benefits of urban forests with respect to urban sustainability and human health; issues related to expanding the urban tree canopy; managing urban forests in a community context; and improving our understanding of urban forests through research and practice.

An analysis of trees in Chicago, IL, reveals that the city has about 3,585,000 trees with canopies that cover 17.2 percent of the area. The most common tree species are white ash, mulberry species, green ash, and tree-of-heaven. Chicago's urban forest currently stores about 716,000 tons of carbon valued at $14.8 million. In addition, these trees remove about 25,200 tons of carbon per year ($521,000 per year) and about 888 tons of air pollution per year ($6.4 million per year). Trees in Chicago are estimated to reduce annual residential energy costs by $360,000 per year. The structural, or compensatory, value is estimated at $2.3 billion. Information on the structure and functions of the urban forest can be used to inform urban forest management programs and to integrate urban forests within plans to improve environmental quality in the Chicago area.

This is the 7th edition of the FAO's biennial report on the state of global forest resources, recent developments and emerging issues in the forest sector. This edition focuses on progress towards sustainable forest management at the regional and global levels, with each regional report structured according to seven thematic elements: the extent of forest resources; biological diversity; forest health and vitality; productive functions of forest resources; protective functions of forest resources; socio-economic functions; and legal, policy and institutional frameworks. These summaries are based on the most current information available, including new data from the Global Forest Resources Assessment 2005 (FRA 2005). The report goes on to consider 18 key issues in the forest sector, including: climate change, forest landscape restoration, forest tenure, invasive species, wildlife management and wood energy. The overall conclusion is that whilst progress is being made, it is very uneven with those regions with developing economies and tropical ecosystems continuing to lose forest area whilst lacking adequate institutions to reverse this trend. The biggest limitation for evaluating progress is weak data, with many countries lacking the financial resources to undertake national forest assessments.

An analysis of trees in Washington, D.C. reveals that this city has about 1,928,000 trees with canopies that cover 28.6 percent of the area. The most common tree species are American beech, red maple, and boxelder. The urban forest currently store about 526,000 tons of carbon valued at $9.7 million. In addition, these trees remove about 16,200 tons of carbon per year ($299,000 per year) and about 540 tons of air pollution per year ($2.5 million per year). The structural, or compensatory, value is estimated at $3.6 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 Washington, D.C. area.

More than half the world's population now lives in cities. Creating sustainable, healthy and aesthetic urban environments is therefore a major policy goal and research agenda. This comprehensive handbook provides a global overview of the state of the art and science of urban forestry. It describes the multiple roles and benefits of urban green areas in general and the specific role of trees, including for issues such as air quality, human well-being and stormwater management. It reviews the various stresses experienced by trees in cities and tolerance mechanisms, as well as cultural techniques for either pre-conditioning or alleviating stress after planting. It sets out sound planning, design, species selection, establishment and management of urban trees. It shows that close interactions with the local urban communities who benefit from trees are key to success. By drawing upon international state-of-art knowledge on arboriculture and urban forestry, the book provides a definitive overview of the field and is an essential reference text for students, researchers and practitioners.

Fully updated and greatly enhanced, the Third Edition of Urban Forestry addresses current issues in planning, establishing, and managing trees, forests, and other elements of nature in urban and community ecosystems. The authors discuss why we have trees in cities and how we use them, clarify the appraisal and inventory of urban vegetation, and extensively delve into the planning and management of public as well as private vegetation. As urban forestry continues to evolve as a profession, foresters and arborists can expect many challenges as well as opportunities. The continuing development of cities has become linked to a much greater emphasis on urban vegetation, the growing demand for recreation amenities within the urban environment, and the careful and successful management of vegetation in an urban ecosystem. New ways to incorporate the highly versatile urban forest resource into the urban fabric will undoubtedly benefit the lives of its residents.
