The 19th century spawned a unique breed of men who took pride in their woodsmen skills and rough codes of conduct. They called themselves lumberers, shantymen, timber beasts, les bucherons and, more recently, lumberjacks, working in the vast forests of eastern Canada and British Columbia.

Across the country, farm boys would go to the woods, lumbering being the only winter work available. Immigrants Swedes and Finns more often than not resumed the trades they had learned so well in the forests...

This collection of black-and-white images conveys the story of human impact on Mississippi's forests from the pioneer era to the present. Photographs gleaned from public and private archives tell a visual tale of the development of Mississippi's forest industries. Historic locomotives course through the woods, oxen drag big timber over rutted terrain, and lookouts perch atop Forest Service towers eyeing the horizon for telltale signs of fire. Photos of life in a portable logging camp reveal early hospitals, lumber company stores, mobile homes, and the advancing technology of logging...

The passionate response of the British public to the Newbury Bypass is a revealing measure of how strongly people feel about trees and the environment. Similarly, in the United States, the giant sequoia of California is an enduring national symbol that inspires intense feelings. As rainforests are sacrificed to the interests of multi-national corporations and traditional ways of life disappear, the status of forests, the cultural significance of trees, and the impact of conservation policies are subjects that have inspired intense engagement. Why do people feel so strongly about trees?...

Edible Forest Gardens is a groundbreaking two-volume work that spells out and explores the key concepts of forest ecology and applies them to the needs of natural gardeners in temperate climates. Volume I lays out the vision of the forest garden and explains the basic ecological principles that make it work. In Volume II, Dave Jacke and Eric Toensmeier move on to practical considerations: concrete ways to design, establish, and maintain your own forest garden. Along the way they present case studies and examples, as well as tables, illustrations, and a uniquely valuable -plant...

Homegardens are integrated tree crop animal production systems, often in small parcels of land surrounding homesteads, and primarily found in tropical environments. These agroforestry systems, developed and nurtured by farmers through generations of innovation and experiment, are often cited as the epitome of sustainability, yet have been long neglected by the scientific community. Today, however, these age-old systems are receiving increasing attention owing to their perceived potential to mitigate environmental problems such as loss of biodiversity and rising levels of atmospheric...

Simply put, allelopathy refers to an ecological phenomenon of plant-plant interference through release of organic chemicals (allelochemicals) in the environment. These chemicals can be directly and continuously released by the donor plants in their immediate environment as volatiles in the air or root exudates in soil or they can be the microbial degradation products of plant residues. The chemicals may interfere with survival and growth of neighboring or succeeding plants. Black walnut, eucalyptus, sunflower, sorghum, sesame and alfalfa are common examples of plants with allelopathic...
