Book Description
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.

Book Description
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

Book Description
This is a state-of-the-science synthesis of the effects of forest harvest activities on peak flows and channel morphology in the Pacific Northwest, with a specific focus on western Oregon and Washington. We develop a database of relevant studies reporting peak flow data across rain-, transient-, and snow-dominated hydrologic zones, and provide 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. Watersheds located in the rain-dominated zone appear to be less sensitive to peak flow changes than those in the transient snow zone; insufficient data limit interpretations for the snow zone. Where present, peak flow effects on channel morphology should be confined to stream reaches where channel gradients are less than approximately 0.02 and streambeds are composed of gravel and finer material. We provide guidance as to how managers might evaluate the potential risk of peak flow increases based on factors such as presence of roads, watershed drainage efficiency, and specific management treatments employed. The magnitude of effects of forest harvest on peak flows in the Pacific Northwest, as represented by the data reported here, are relatively minor in comparison to other anthropogenic changes to streams and watersheds.
