Book Synopsis Early Effects of Manipulating Aspen Density and Special Arrangement on Lodgepole Pine Performance, Aspen Sucker Production and Stand Development in an 11-year Old Stand in the SBPSxc Subzone of South-central British Columbia by : Teresa A. Newsome
Download or read book Early Effects of Manipulating Aspen Density and Special Arrangement on Lodgepole Pine Performance, Aspen Sucker Production and Stand Development in an 11-year Old Stand in the SBPSxc Subzone of South-central British Columbia written by Teresa A. Newsome and published by . This book was released on 2006 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixtures of trembling aspen (Populus tremuloides Michx.) and lodgepole pine (Pinus contorta var. latifolia Engelm.) regenerate naturally throughout the Sub-Boreal Pine-Spruce (SBPS), Interior Douglas-fir (IDF), Sub-Boreal Spruce (SBS), and Interior Cedar-Hemlock (ICH) zones in the Cariboo-Chilcotin area of the Southern Interior Forest Region. Due to the rapid height growth and high initial sucker densities of young aspen, these stands generally require some management at the juvenile stage to meet conifer growth objectives. Strategies designed to lessen competition from young aspen have become more complex over the past decade. In light of current understanding of the importance of broadleaf tree species to overall ecosystem health, successful management of young pine-aspen stands now requires practitioners to find a balance between removing aspen to meet lodgepole pine growth objectives and retaining as much aspen as possible to preserve the ecosystem benefits conferred by broadleaf species, reduce suckering, and reduce silviculture treatment costs. The Clusko aspen removal study, established in 2001 in an 11-year-old lodgepole pine-trembling aspen stand in the SBPSxc subzone, investigates the effects of five levels of aspen removal on target pine, neighbourhood competitive interactions, and stand development. Treatments include: (1) an untreated control; (2) complete aspen removal; broadcast retention of (3) 1000 and (4) 2500 aspen stems ha-1; and (5) a spatial treatment that removed aspen within a 1-m radius around target pine. This report presents second-year results from the Clusko River (Clusko) study.
Book Synopsis 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 by : Teresa A. Newsome
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.

Book Synopsis Guidelines for Developing Stand Density Management Regimes by : British Columbia. Forest Practices Branch
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 Synopsis Competitive Effects of Trembling Aspen on Lodgepole Pine Performance in the SBS and IDF Zones of the Cariboo-Chilcotin Region of South-central British Columbia by : Teresa A. Newsome
Download or read book Competitive Effects of Trembling Aspen on Lodgepole Pine Performance in the SBS and IDF Zones of the Cariboo-Chilcotin Region of South-central British Columbia written by Teresa A. Newsome and published by . This book was released on 2003 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes & presents results of a retrospective study carried out between 1992 and 1999 in the Cariboo-Chilcotin region of British Columbia to quantify the effects of trembling aspen competition on lodgepole pine performance, and to identify competition indices or other measures of competition that could be used by field staff. Target pine were selected across neighbourhoods in six stands with varying densities of aspen. Data pertaining to pine size & condition, and to the size & location of aspen within a 70-inch radius of the pine were collected three times. Measurements began when the stands were seven to 12 years old. Various approaches are used to identify levels of aspen abundance when pine performance declined below acceptable levels. These include analyses of regression & correlation, tests of existing competition indices, and visual & statistical characterization of trends. Finally, conservative recommendations are made for the retention of aspen within pine stands in the Cariboo-Chilcotin region.

Book Synopsis Relative Impact of Aspen Competition and Soil Factors on the Performance of Lodgepole Pine and Hybrid White Spruce in North-central British Columbia by : C. DeLong
Download or read book Relative Impact of Aspen Competition and Soil Factors on the Performance of Lodgepole Pine and Hybrid White Spruce in North-central British Columbia written by C. DeLong and published by . This book was released on 2007 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Releasing conifers from the competition effects of aspen (Populus tremuloides Michx.) is a key focus of plantation management in sub-boreal and boreal forests, often at considerable cost. However, other factors affect early plantation performance. This study investigates the relative influence of aspen competition and soil factors on the performance of planted lodgepole pine (Pinus contorta Dougl. ex Loud.) and hybrid white spruce (Picea glauca [Moench] Voss x engelmannii Parry ex Engelm.) in north-central British Columbia. Plots were established across a gradient of natural aspen competition levels that resulted from a test of aspen control treatments at one site. Within these plots, 240 of each of the target conifer species were measured and their immediate soil and vegetative environment quantified. Regression trees and regression analysis were used to examine the importance of aspen competition relative to other factors in determining target conifer size."--Document.
