Shaped by fire for thousands of years, the forests of the western United States are as adapted to periodic fires as they are to the region's soils and climate. Our widespread practice of ignoring the vital role of fire is costly in both ecological and economic terms, with consequences including the decline of important fire-dependent tree and undergrowth species, increasing density and stagnation of forests, epidemics of insects and diseases, and the high potential for severe wildfires.
Flames in Our Forest explains those problems and presents viable solutions to them. It explores the underlying historical and ecological reasons for the problems associated with our attempts to exclude fire and examines how some of the benefits of natural fire can be restored Chapters consider:
Flames in Our Forest presents a new picture of the role of fire in maintaining forests, describes the options available for restoring the historical effects of fires, and considers the implications of not doing so. It will help readers appreciate the importance of fire in forests and gives a nontechnical overview of the scientific knowledge and tools available for sustaining western forests by mimicking and restoring the effects of natural fire regimes.

Back in print at last in a third edition, the classic Forest and Shade Trees of Iowa now has a wealth of full-color photographs and updated, reorganized information that will please both new and returning readers.
Part 1 of this guide focuses on identification, with user-friendly keys to both summer and winter trees and illustrated descriptions of more than one hundred common species. The trees are arranged according to similarities in foliage; each entry includes a large scan of a leafy branch along with two or three smaller photos of buds, flowers, fruits, and winter twigs. The text contains a description of the species, its geographical distribution, and notes on how to distinguish it from similar species. Part 2 is divided into conifers and flowering trees and includes all trees native to Iowa, trees that are widely planted, invasive species, some less commonly planted trees, and tall native shrubs that might be mistaken for trees. The authors provide information about the natural history of individual trees, their ecological requirements, pests and diseases that affect them, and their usefulness for such different purposes as windbreaks, landscaping, wildlife plantings, fuel, lumber, and food. Following these two main parts, three shorter sections describe the planting and care of trees, Iowa’s forest communities, and good places to see trees in the state; a glossary and a bibliography are also included.
A complete guide to Iowa’s trees, both native and introduced, full of hundreds of color photos, this new edition of Forest and Shade Trees of Iowa will be immensely useful to arborists, foresters, horticulturists, landscape architects, gardeners, and all Iowans and midwesterners who appreciate the beauty and value of trees and want to learn more about them.
If sociology could teach everyone just one thing, what would it be? The Forest and the Trees is one sociologist's response to the hypothetical—the core insight with the greatest potential to change how people see the world and themselves in relation to it.
This revised and updated edition features:
• A new chapter that brings together the various aspects of the sociological model described in previous chapters with a detailed application to the origins of racism in the United States
•A discussion of how individuals can participate in social change by stepping off paths of least resistance
•The addition of graphics to illustrate the sociological model of systems and individuals
First published in 1990, Forests explores the ecological, economic, and human influences on over thirty significant types of woodlands. Laurence Walker focuses especially on the effects of site factors—climate, physiography, biology, and soils—upon the growth of various kinds of trees. Projects for amateur naturalists, reading lists, and a glossary make this the perfect introduction for general readers.
