Includes a database of relevant studies reporting peak flow data across rain-, transient-, and snow-dominated hydrologic zones. Provides a quantitative comparison of changes in peak flow across both a range of flows and forest practices. Increases in peak flows generally diminish with decreasing intensity of percentage of watershed harvested and lengthening recurrence intervals of flow. Peak flow effects on channel morphology should be confined to stream reaches where channel gradients are less than 0.02 and streambeds are composed of gravel and finer material. Managers should evaluate the potential risk of peak flow increases based on factors such as presence of roads, specific mgmt. treatments employed, and watershed drainage efficiency.

For 70 years, people have turned to one book to learn about Northwest trees: Trees to Know in Oregon. This new edition, retitled Trees to Know in Oregon and Washington, expands its scope to cover more territory and include more trees. The book was first published in 1950. Charles R. Ross, an Oregon State University Extension forester, wanted to introduce readers to the towering giants in their backyards. Since then, Edward C. Jensen has stewarded the publication through several more editions. This edition features several rare species native to southwest Oregon. It also updates scientific names and adds a new section on how Northwest forests are likely to be affected by changing climates. Since its initial publication, Trees to Know has become a mainstay for students, gardeners, small woodland owners and visitors to the Pacific Northwest. Along with all the details on native conifers, broadleaves, and more than 50 ornamental trees, readers will find: More than 400 full-color photos and 70 maps depicting habitat, range and forest type. Easy-to-follow identification keys. Handy guides to help distinguish one variety from another. The story of Northwest forests -- past, present and future.

This gracefully written story shows all that is lost when we destroy ancient stands of trees--as revealed through a 60-year study of the flora and fauna in an Oregon Coast Range forest that is selectively logged and finally clear-cut.

This major volume presents a wealth of fundamental and applied research on managing Coast Range forest and stream ecosystems. Written primarily for managers and resource specialists, the book will also appeal to policymakers, resource scientists, forest landowners, the conservation community, and students interested in forestry, fisheries, and wildlife sciences.

That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.
