This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2008, a Working Group that included British Columbia government staff (researchers, stewardship foresters, and wildlife habitat experts), a research consultant, and industry foresters was formed in the Cariboo Region of south-central British Columbia to determine how existing research concerning conifer#x13;broadleaf competitive relationships could be used to suggest change to free-growing guidelines for that region. The objective was to adjust free-growing criteria concerning broadleaf tree presence in coniferous plantations while maintaining consistency with biological thresholds for conifer growth that had been determined by local research. ...
Download or read book Effects of Variable Aspen Retention on Stand Development Aspen Sucker Production and Growth of Lodgepole Pine in the SBSdw1 Variant of South central British Columbia written by Teresa A. Newsome and published by . This book was released on 2006 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixtures of trembling aspen (Populus tremuloides Michx.) and naturally regenerated or planted lodgepole pine (Pinus contorta var. latifolia Engelm. ex S. Wats.) occur throughout interior British Columbia. To develop effective management strategies for mixed stands where softwood timber production is the primary objective, silviculturists need information about levels of broadleaves that can be retained without seriously reducing conifer performance. They also require practical guidance on using this information to develop cost-effective treatment prescriptions. To address this topic in the Cariboo-Chilcotin, a pine-aspen competition project that includes studies in a variety of ecosystems is currently under way. In 1999, an operational trial to study the effects of variable aspen retention on stand-level lodgepole pine performance and aspen sucker production was established near McKinley Lake in the SBSdw1 variant of the Central Cariboo Forest District. The study was a co-operative undertaking by the B.C. Ministry of Forests and Weldwood of Canada, Ltd. In 2002, the study was adopted by the Silvicultural Systems Research Group of the Southern Interior Forest Region as part of the pine-aspen competition project, and objectives and methods were subsequently adapted to include the collection of long-term growth and yield and stand development data. This report summarizes fourth-year pine and aspen responses to aspen retention treatments, and provides baseline stand development information.

Download or read book Lodgepole Pine Response to Aspen Removal in Variable Radii in the SBSdw2 Variant Near Williams Lake B C written by Teresa A. Newsome and published by British Columbia, Forest Science Program. This book was released on 2004 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed forests of lodgepole pine (Pinus contorta var. latifolia Engelm.) and trembling aspen (Populus tremuloides Michx.) are common throughout interior British Columbia, particularly in north and central areas of the province. In the Cariboo-Chilcotin area of the Southern Interior Forest Region, aspen commonly regenerates along with planted and natural lodgepole pine in the Sub-Boreal Spruce (SBS), Interior Douglas-fir (IDF), Sub-Boreal Pine-Spruce (SBPS), and Interior Cedar-Hemlock (ICH) zones. Historically, aspen has been regarded as a "weed" that competes with conifers, but silviculturists now recognize that there are many benefits to maintaining a broadleaf component within stands. A study was established in 1994 in the SBSdw2 variant of the Cariboo-Chilcotin region of the Southern Interior Forest Region to investigate the effects of removing aspen in 50 or 100 cm radii around crop lodgepole pine versus broadcast removal or no treatment. The primary objective of the study was to assess whether the free-growing criterion (current in 1994), which specified that no overtopping vegetation could be present within a 1 m radius around crop trees, was appropriate in pine-aspen stands, or whether a 50 cm radius zone would be adequate.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1991, Traditional Plant Foods of Canadian Indigenous Peoples details the nutritional properties, botanical characteristics and ethnic uses of a wide variety of traditional plant foods used by the Indigenous Peoples of Canada. Comprehensive and detailed, this volume explores both the technical use of plants and their cultural connections. It will be of interest to scholars from a variety of backgrounds, including Indigenous Peoples with their specific cultural worldviews; nutritionists and other health professionals who work with Indigenous Peoples and other rural people; other biologists, ethnologists, and organizations that address understanding of the resources of the natural world; and academic audiences from a variety of disciplines.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

Download or read book Guidelines for Developing Stand Density Management Regimes written by British Columbia. Forest Practices Branch and published by British Columbia, Forest Practices Branch. This book was released on 1999 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stand density management is the process of controlling tree density within a stand to achieve desired objectives. Stand density management practices include the spacing of planted trees, pre-commercial thinning, and commercial thinning. A sound density management prescription must consider three elements of prediction: biological responses of the stand to treatment, economic implications of the treatment, and forest-level effects of the treatment. This document provides essential information on each of these elements, and provides a structured decision process for making site-specific density management prescriptions. Sections of the document cover the biological concepts of timber production, economic principles of timber production, forest planning considerations, the decision process, and density management planning tools. Includes glossary.

Book excerpt: The Archive of Place weaves together a series of narratives about environmental history in a particular location � British Columbia's Chilcotin Plateau. In the mid-1990s, the Chilcotin was at the centre of three territorial conflicts. Opposing groups, in their struggle to control the fate of the region and its resources, invoked different understandings of its past � and different types of evidence � to justify their actions. These controversies serve as case studies, as William Turkel examines how people interpret material traces to reconstruct past events, the conditions under which such interpretation takes place, and the role that this interpretation plays in historical consciousness and social memory. It is a wide-ranging and original study that extends the span of conventional historical research.
