Environmental Issues in Pacific Northwest Forest Management
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309053285
Category : Technology & Engineering
Languages : en
Pages : 280
Book Description
People are demanding more of the goods, services, and amenities provided by the forests of the Pacific Northwest, but the finiteness of the supply has become clear. This issue involves complex questions of biology, economics, social values, community life, and federal intervention. Forests of the Pacific Northwest explains that economic and aesthetic benefits can be sustained through new approaches to management, proposes general goals for forest management, and discusses strategies for achieving them. Recommendations address restoration of damaged areas, management for multiple uses, dispute resolution, and federal authority. The volume explores the market role of Pacific Northwest wood products and looks at the implications if other regions should be expected to make up for reduced timber harvests. The book also reviews the health of the forested ecosystems of the region, evaluating the effects of past forest use patterns and management practices. It discusses the biological importance, social significance, and management of old-growth as well as late-succession forests. This volume will be of interest to public officials, policymakers, the forest products industry, environmental advocates, researchers, and concerned residents.
Global to Local: Ecological Land Classification
Author: Richard A. SimsPublisher: Springer Science & Business Media
ISBN: 9400916531
Category : Technology & Engineering
Languages : en
Pages : 619
Book Description
Ecological Land Classification (ELC) refers to the description of land resources at a range of spatial resolutions (i.e. global to local) and for a range of purposes or values. The emerging science of ELC is in fact a very carefully integrated blend of vegetation and earth sciences, climatology, cartography and ecology with a range of new technologies and methodologies including computer-based geographic information systems, remote sensing and simulation modelling. This publication defines the current `state-of-the-art' of ELC. It provides particular insight into the role of ELC in current and future forest resource planning and management, and emphasizes its application and usefulness at various spatial scales, for a variety of geographic locations, and under a range of management scenarios/constraints. The book is an invaluable and substantial reference source about the current trends in ELC and will be of particular value to ecologists, foresters, geographers, resource managers, wildlife biologists, GIS and remote sensing specialists, educators and students.

Silvicultural Options for Young-growth Douglas-fir Forests
Author: Publisher:
ISBN:
Category : Douglas fir
Languages : en
Pages : 128
Book Description
This report describes the origin, design, establishment and measurement procedures and first results of a large long-term cooperative study comparing a number of widely different silvicultural regimes applied to young-growth Douglas-fir (Pseudotsuga menziesii) stands managed for multiple objectives. Regimes consist of (1) conventional clearcutting followed by intermediate thinning; (2) retention of reserve trees to create a two-aged stand; (3) small patch cuts dispersed within a thinned matrix, repeated at approximately 15-year intervals to create a mosaic of age classes; (4) group selection within a thinned matrix on an approximate 15-year cycle; (5) continued thinning on an extended rotation; and (6) an untreated control. Each of these regimes is on operationsize units (about 30 to 70 acres each). Output variables to be evaluated include conventional timber growth and yield statistics, harvest costs, sale layout and administration costs, aesthetic effects and public acceptance, soil disturbance, bird populations, and economic aspects. Descriptive statistics and some initial results are presented for the first replicate, established in 1997-98.
