An intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.

An appreciation of the beautiful, iconic, and endangered Eastern Hemlock and what it means to nature and society The Eastern Hemlock, massive and majestic, has played a unique role in structuring northeastern forest environments, from Nova Scotia to Wisconsin and through the Appalachian Mountains to North Carolina, Tennessee, and Alabama. A “foundation species” influencing all the species in the ecosystem surrounding it, this iconic North American tree has long inspired poets and artists as well as naturalists and scientists. Five thousand years ago, the hemlock collapsed as a result of abrupt global climate change. Now this iconic tree faces extinction once again because of an invasive insect, the hemlock woolly adelgid. Drawing from a century of studies at Harvard University’s Harvard Forest, one of the most well-regarded long-term ecological research programs in North America, the authors explore what hemlock’s modern decline can tell us about the challenges facing nature and society in an era of habitat changes and fragmentation, as well as global change.

In 1977 David Foster took to the woods of New England to build a cabin with his own hands. Along with a few tools he brought a copy of the journals of Henry David Thoreau. Foster was struck by how different the forested landscape around him was from the one Thoreau described more than a century earlier. The sights and sounds that Thoreau experienced on his daily walks through nineteenth-century Concord were those of rolling farmland, small woodlands, and farmers endlessly working the land. As Foster explored the New England landscape, he discovered ancient ruins of cellar holes, stone walls, and abandoned cartways--all remnants of this earlier land now largely covered by forest. How had Thoreau's open countryside, shaped by ax and plough, divided by fences and laneways, become a forested landscape? Part ecological and historical puzzle, this book brings a vanished countryside to life in all its dimensions, human and natural, offering a rich record of human imprint upon the land. Extensive excerpts from the journals show us, through the vividly recorded details of daily life, a Thoreau intimately acquainted with the ways in which he and his neighbors were changing and remaking the New England landscape. Foster adds the perspective of a modern forest ecologist and landscape historian, using the journals to trace themes of historical and social change. Thoreau's journals evoke not a wilderness retreat but the emotions and natural history that come from an old and humanized landscape. It is with a new understanding of the human role in shaping that landscape, Foster argues, that we can best prepare ourselves to appreciate and conserve it today. From the journal: "I have collected and split up now quite a pile of driftwood--rails and riders and stems and stumps of trees--perhaps half or three quarters of a tree...Each stick I deal with has a history, and I read it as I am handling it, and, last of all, I remember my adventures in getting it, while it is burning in the winter evening. That is the most interesting part of its history. It has made part of a fence or a bridge, perchance, or has been rooted out of a clearing and bears the marks of fire on it...Thus one half of the value of my wood is enjoyed before it is housed, and the other half is equal to the whole value of an equal quantity of the wood which I buy." --October 20, 1855

"Originally published in the June 11, 1984, New Yorker, this lengthy essay is a sharp-edged inquiry into the generational institutions of our national life. George Trow tells the story of upstate New York's Black Rock Forest - a 3,800-acre site overlooking the Hudson River - through the lives of the men who were connected to it and through the larger histories of Harvard University, U.S. conservation policies, and physics and biology. His story is ultimately a symbolic tale that bears upon some of the most significant institutions, professions, and legacies in contemporary American life"--Book jacket.

Maps capture data expressing the economic complexity of countries from Albania to Zimbabwe, offering current economic measures and as well as a guide to achieving prosperity Why do some countries grow and others do not? The authors of The Atlas of Economic Complexity offer readers an explanation based on "Economic Complexity," a measure of a society's productive knowledge. Prosperous societies are those that have the knowledge to make a larger variety of more complex products. The Atlas of Economic Complexity attempts to measure the amount of productive knowledge countries hold and how they can move to accumulate more of it by making more complex products. Through the graphical representation of the "Product Space," the authors are able to identify each country's "adjacent possible," or potential new products, making it easier to find paths to economic diversification and growth. In addition, they argue that a country's economic complexity and its position in the product space are better predictors of economic growth than many other well-known development indicators, including measures of competitiveness, governance, finance, and schooling. Using innovative visualizations, the book locates each country in the product space, provides complexity and growth potential rankings for 128 countries, and offers individual country pages with detailed information about a country's current capabilities and its diversification options. The maps and visualizations included in the Atlas can be used to find more viable paths to greater productive knowledge and prosperity.

Forest Plans of North America presents case studies of contemporary forest management plans developed for forests owned by federal, state, county, and municipal governments, communities, families, individuals, industry, investment organizations, conservation organizations, and others in the United States, Canada, and Mexico. The book provides excellent real-life examples of contemporary forest planning processes, the various methods used, and the diversity of objectives and constraints faced by forest owners. Chapters are written by those who have developed the plans, with each contribution following a unified format and allowing a common, clear presentation of the material, along with consistent treatment of various aspects of the plans. This work complements other books published by members of the same editorial team (Forest Management and Planning, Introduction to Forestry and Natural Resource Management), which describe the planning process and the various methods one might use to develop a plan, but in general do not, as this work does, illustrate what has specifically been developed by landowners and land managers. This is an in-depth compilation of case studies on the development of forest management plans by the different landowner groups in North America. The book offers students, practitioners, policy makers, and the general public an opportunity to greatly improve their appreciation of forest management and, more importantly, foster an understanding of why our forests today are what they are and what forces and tools may shape their tomorrow. Forest Plans of North America provides a solid supplement to those texts that are used as learning tools for forest management courses. In addition, the work functions as a reference for the types of processes used and issues addressed in the early 21st century for managing land resources. Presents 40-50 case studies of forest plans developed for a wide variety of organizations, groups, and landowners in North America Illustrates plans that have specifically been developed by landowners and land managers Features engaging, clearly written content that is accessible rather than highly technical, while demonstrating the issues and methods involved in the development of the plans Each chapter contains color photographs, maps, and figures
