Book Description
The Aquatic Conservation Strategy (ACS) of the Northwest Forest Plan guides management of riparian and aquatic ecosystems on federal lands in western Oregon, western Washington, and northern California. We applied new scientific findings and tools to evaluate two potential options, A and B, for refining interim riparian reserves to meet ACS goals and likely challenges of climate change while supporting other management goals, including timber production. Interim riparian reserves are retained in late-successional reserves and other special land designations in the options. In lands designated as matrix, the area for aquatic conservation extends upslope one site-potential tree-height along all streams, divided into an inner zone devoted solely to achieving ACS goals and an outer zone managed to achieve ACS and other goals. Option A uses a fixed-width approach and option B a context-dependent approach, with partitioning of zones based on the ecological sensitivity of stream reaches. Based on simulations of the area of interim riparian reserves in six watersheds in western Oregon with lands managed by the Bureau of Land Management (BLM): (1) about 76 percent under option A and 72 percent under option B remain solely devoted to ACS goals; (2) 15 percent under option A and 19 percent under option B should be able to meet ACS goals and also contribute toward matrix goals such as timber production; and (3) 9 percent would be returned to matrix. A large percentage of streams with high ecological sensitivity occurred on nonfederal lands, a circumstance that merits further analysis in the context of landscape-scale considerations for biodiversity and recovery of species listed under the Endangered Species Act. Information needs remain with regard to the application and effectiveness of these options, and an adaptive management context is critical for continued improvement.

Book Description
Forests throughout the world are undergoing rapid, far-reaching change as a result of natural and anthropogenic disturbances. The challenge is to manage these forests in ways that avoid formulaic approaches to complex issues. This book takes on the challenge of balancing local economies, wood products, and biodiversity by proposing diverse new approaches to forest management using new research from the moist coniferous forests of the Pacific Northwest. --

Introduction to Forestry and Natural Resources
Author: Donald L. Grebner
Publisher: Academic Press
ISBN: 0128190760
Category : Technology & Engineering
Languages : en
Pages : 513
Book Description
Introduction to Forestry and Natural Resources, Second Edition, presents a broad, completely updated overview of the profession of forestry. The book details several key fields within forestry, including forest management, economics, policy, utilization and forestry careers. Chapters deal specifically with forest regions of the world, landowners, forest products, wildlife habitats, tree anatomy and physiology, and forest disturbances and health. These topics are ideal for undergraduate introductory courses and include numerous examples and questions for students to ponder. There is also a section dedicated to forestry careers. Unlike other introductory forestry texts, which focus largely on forest ecology rather than practical forestry concepts, this book encompasses the economic, ecological and social aspects, thus providing a uniquely balanced text. The wide range of experience of the contributing authors equips them especially well to identify missing content from other texts in the area and address topics currently covered in corresponding college courses. - Covers the application of forestry and natural resources around the world with a focus on practical applications and graphical examples - Describes basic techniques for measuring and evaluating forest resources and natural resources, including fundamental terminology and concepts - Includes management policies and their influence at the local, national and international levels

Riparian and Aquatic Habitats of the Pacific Northwest and Southeast Alaska
Author: Fred H. Everest
Publisher:
ISBN:
Category : Aquatic habitats
Languages : en
Pages : 146
Book Description
Management of riparian habitats is controversial because land use policies have historically emphasized economic values (e.g., timber production) at the expense of ecological and social values. Attempting to manage these valuable resources to attain the greatest combination of benefits has created a long-term controversy that continues to the present. Our analysis indicates that at mid to large spatial scales, healthy riparian ecosystems and land management activities are not mutually exclusive, but the degree of compatibility is determined by policy decisions based on competing demands and pressing timelines as well as available scientific knowledge. Current management schemes on federal lands in the Pacific Northwest and Alaska are appropriately addressing large spatial scales and incorporating the principles of disturbance ecology. We found no scientific evidence that either the default prescriptions or the options for watershed analysis in the Northwest Forest Plan and Tongass Land Management Plan provide more protection than necessary to meet stated riparian management goals. We believe that additional alternative riparian management strategies could be implemented and evaluated in concert to shorten the time needed to realize effective strategies that fully meet riparian management goals.

Book Description
Ecosystem management has gained widespread visibility as an approach to the management of land to achieve sustainable natural resource use. Despite widespread interest in this emerging management paradigm, Ecosystems: Balancing Science with Management is the first book to directly propose approaches for implementing ecosystem management, give examples of viable tools, and discuss the potential implications of implementing an ecosystem approach. These ideas are framed in a historical context that examines the disjunction between ecological theory, environmental legislation and natural resources management.
