Book Description
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.

Stand Management Prescription Guidebook
Author: British Columbia. Ministry of Forests
Publisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 56
Book Description
A stand management prescription is a document for describing actions to be carried out on a free-growing site to see that stand management activities are planned and implemented to maintain or enhance site productivity, to ensure that resource values are identified and taken into account, and to set out a series of stand management activities to produce a stand that meets the management objectives. This guide provides a logical sequence of steps on how to prepare and administer a stand management prescription in accordance with the Forest Practices Code of British Columbia. These steps include identification and collection of background information, setting of stand-level resource objectives, conducting fieldwork, preparation of the final prescription, production of the stand management prescription map, and administration.

Guidelines for Developing Stand Density Management Regimes
Author: British Columbia. Forest Practices Branch
Publisher: British Columbia, Forest Practices Branch
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 110
Book Description
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.

Plant Geography
Author: Rexford Daubenmire
Publisher: Elsevier
ISBN: 032315493X
Category : Science
Languages : en
Pages : 347
Book Description
Plant Geography: With Special Reference to North America covers main concepts of the two major approaches to plant geography, namely, the floristic plant geography and the ecologic plant geography. Floristic plant geography primarily studies evolutionary divergence, migration, and decline of taxa, as influenced by past events of the earth's history. Ecologic plant geography is an alternative approach to plant geography, which takes plant communities as units having ranges to be interpreted, dominated by sociologic and physiologic, rather than phylogenetic and historic considerations. Under the floristic plant geography part, topics covered include interrelations among floristic plant geography, taxonomy, and geology; the relation between plant dissemination and migration; evidence of the dynamic character of plant ranges; and migratory route. After a brief introduction to the evolution of North and South America vegetation, the book discusses the ecologic plant geography section that focuses on various vegetation regions in North America, including Tundra, subarctic-subalpine forest, temperate mesophytic, xerophytic forest, and chaparral and steppe regions and temperate affinity forests in Middle America. Other regions examined include the desert and marine regions, as well as the microphyllous woodland, tropical savanna, rain forest, and tropical alpine. With great information on geologic history of each vegetation unit and paleontology, this book will be helpful to paleobotanists, historical geologists, and taxonomists.

Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 48
Book Description
This guide is designed to provide a reference for identifying, detecting, assessing, and treating pine stem rusts in managed forest stands.
