This unique book celebrates and documents the incredible and colorful biodiversity of the mountain landscapes of eastern North America, covering all of the major alpine ecosystems in New England, New York, Québec, Newfoundland, and Labrador. Twenty scientists, explorers, naturalists, and land managers from the United States and Canada have collaborated to create this definitive and beautiful account of the flora and fauna of the eastern alpine tundra.

Humans have occupied mountain environments and relied on mountain resources since the terminal Pleistocene. Their continuous interaction with the land from generation to generation has left material imprints ranging from anthropogenic fires to vision quest sites. The diverse case studies presented in this collection explore the material record of North American mountain dwellers and habitual users of high-elevation resources in terms of social investment—the intergenerational commitment of a group to a particular landscape. Contributors look creatively at the significance of social investment and its material and nonmaterial consequences, addressing landscape engineering at different times through diverse theoretical standpoints and archaeological, historical, and ethnographic data from varied mountain environments. Together, these original contributions demonstrate that social investment encompasses timeless ecological and ritual knowledge as well as innovation born from daily practice, tradition, and periodic adjustment to fit new social and political imperatives. Engineering Mountain Landscapes offers both substantive ideas of broad intellectual interest, specific case studies with state-of-art methodology, and a wealth of comparative data.

For more than a century, the world has recognized the extraordinary biological diversity of the forests of Tanzania’s Usambara Mountains. As international attention has focused on forest conservation, farmers, foresters, biologists, and the Tanzanian state have realized that only complex negotiations will save these treasured, but rapidly disappearing, landscapes. Highland Sanctuary unravels the complex interactions among agriculture, herding, forestry, the colonial state, and the landscape itself. In his examination of the region’s history of ecological transformation, Christopher Conte demonstrates how these forces have combined to create an ever-changing mosaic of forest and field. His study illuminates the debate over conservation, arguing that contingency and chance, the stuff of human history, have shaped forests in ways that rival the power of nature. In Highland Sanctuary, the forest becomes part of human history, rather than something outside of it. Highland Sanctuary cuts through a legacy of contention and ill will to inform contemporary conservation initiatives. Professor Conte explains how ecological changes take divergent paths in similar environments, in this case on mountains that harbor unique flora and fauna, and how these mountain environments achieve international importance as centers of biodiversity.

Why do quaking aspens grow in prominent clumps rather than randomly scattered across the landscape? Why and how does a rufous hummingbird drop its metabolism to one-hundredth of its normal rate? Why do bull elk grow those enormous antlers? Using his experience as a biologist and ecologist, George Constantz illuminates these remarkable slices of mountain life in plain but engaging language. Whether it sketches conflict or cooperation, surprise or familiarity, each story resolves when interpreted through the theory of evolution by natural selection.
 
These provocative accounts of birds, insects, rodents, predators, trees, and flowers are sure to stir the reader’s curiosity. Who wouldn’t be intrigued by a rattlesnake’s ability to hunt in total darkness by detecting the infrared radiation emitted by a mouse? Or how white-tailed ptarmigan thrive in their high, treeless alpine environments -- even through the winter? The narratives, often brought home with a counterintuitive twist, invite readers to make new connections and broaden perspectives of a favorite outdoor place. 

All previous books dealing with prehistoric hunter-gatherers in the high Andes have treated ancient mountain populations from a troglodyte's perspective, as if they were little different from lowlanders who happened to occupy jagged terrain. Early mountain populations have been transformed into generic foragers because the basic nature of high-altitude stress and biological adaptation has not been addressed. In Montane Foragers, Mark Aldenderfer builds a unique and penetrating model of montane foraging that justly shatters this traditional approach to ancient mountain populations.

Aldenderfer's investigation forms a methodological and theoretical tour de force that elucidates elevational stress—what it takes for humans to adjust and survive at high altitudes. In a masterful integration of mountain biology and ecology, he emphasizes the nature of hunter-gatherer adaptations to high-mountain environments. He carefully documents the cultural history of Asana, the first stratified, open-air site discovered in the highlands of the south-central Andes. He establishes a number of major occurrences at this revolutionary site, including the origins of plant and animal domestication and transitions to food production, the growth and packing of forager populations, and the advent of some form of complexity and social hierarchy.

The rich and diversified archaeological record recovered at Asana—which spans from 10,000 to 3,500 years ago—includes the earliest houses as well as public and ceremonial buildings in the central cordillera. Built, used, and abandoned over many millennia, the Asana structures completely transform our understanding of the antiquity and development of native American architecture. Aldenderfer's detailed archaeological case study of high-elevation foraging adaptation, his description of this extreme environment as a viable human habitat, and his theoretical model of montane foraging create a new understanding of the lifeways of foraging peoples worldwide.

In The Mountain, geographers Bernard Debarbieux and Gilles Rudaz trace the origins of the very concept of a mountain, showing how it is not a mere geographic feature but ultimately an idea, one that has evolved over time, influenced by changes in political climates and cultural attitudes. To truly understand mountains, they argue, we must view them not only as material realities but as social constructs, ones that can mean radically different things to different people in different settings.
 
From the Enlightenment to the present day, and using a variety of case studies from all the continents, the authors show us how our ideas of and about mountains have changed with the times and how a wide range of policies, from border delineation to forestry as well as nature protection and social programs, have been shaped according to them. A rich hybrid analysis of geography, history, culture, and politics, the book promises to forever change the way we look at mountains.

Tree Lines unites striking ink drawings of high-altitude pine trees with poetic vignettes about how people interact with mountain environments. The drawings and text work together to form a direct artistic encounter with timberline conifers. The husband and wife team of Valerie and Michael Cohen employ a unique process whereby she draws in isolation, gives him her drawings, and he then writes whatever he’s inspired to create. Neither offers the other any kind of feedback or instruction. The result is an accessible and deeply engaging work that is also extremely well researched; the Cohens bring a lifetime of scholarship in literature, history, and the environment to this work.

The drawings are black-and-white, pen-and-ink representations of high alpine ecosystems. The prose is stripped bare, abbreviated in an epigrammatic style that is poetic and spontaneous. Trees represented here are the Western Juniper or Sierra Juniper, the Limber, and the Bristlecone Pine—three species of long-lived, slow-growing conifers that grow across the Great Basin. While they represent only a small portion of the vegetative culture high in the western mountains, the Cohens use representation as abstraction as is utilized by writers and artists to convey a unique kind of microcosm of our natural environment. This book compares to such classics as Leopold’s A Sand County Almanac, and Berger’s Ways of Seeing, which open up lines of observation, analysis, and art for a new generation of readers.
