Guide describing the lowland and montane ecosystems (below 1200 m in the south and 1050 m in the north) in B.C.'s northeastern corner. The units in the guide are described in the biogeoclimatic ecosystem classification system. The guide includes a description of the biogeoclimatic units included and differentiates them, and then describes the site units within each variant, and their management interpretation.
Explores the relationships between forest management activities and timber quality. Sessions were organized to explore models and simulation methodologies that contribute to an understanding of tree development over time and the ways that management and harvesting activities can influence the quality of timber products recovered from those trees. Five keynote addresses, 29 plenary presentations, and 16 poster presentations covered the full breadth of forest growth and timber quality issues related to forest management. These proceedings comprise 19 papers based on presentations and posters, plus 28 abstracts for presentations. Also includes abstracts and slides from the presentations prepared by three keynote speakers. Illustrations.
This guide has two main goals: to assist users in classifying sample forest ecosystem sites in the field in the south-east Prince George Forest Region; and to provide interpretations for these site units that will assist in preparing management prescriptions. Following the introduction is a brief discussion of the biogeoclimatic classification system. Chapter 3 contains procedures for site description, identification, mapping, & interpretation. Chapters 4 to 11 present information about the biogeoclimatic units in the Region, tools for identification of biogeoclimatic & site units, descriptions of the site units, and direct management interpretations for the identified site units. Chapter 12 provides indirect interpretations for silvicultural systems and site preparation options, as well as some basic information on ecosystem management.
This Field guide describes the ecological units of the Rocky Mountain Trench, Prince George Forest Region. It represents aides to the identification of these units and management interpretations for each.
Descriptions, maps, illustrations and tables of British Columbia's biogeoclimatic zones, as well as an overview of how the biogeoclimatic zone system was developed.
This field guide describes the seral aspen ecosystem units of the Murray River variant (BWBSc1), of the Moist Warm Boreal White and Black Spruce zone in the Prince George Forest Region. It presents aids to the identification of these units, and management interpretations for each unit.
Martens and Fishers (Martes) in Human-Altered Environments: An International Perspective examines the conditions where humans and martens are compatible and incompatible, and promotes land use practices that allow Martes to be representatively distributed and viable. All Martes have been documented to use forested habitats and 6 species (excluding the stone marten) are generally considered to require complex mid- to late-successional forests throughout much of their geographic ranges. All species in the genus require complex horizontal and vertical structure to provide escape cover protection from predators, habitat for their prey, access to food resources, and protection from the elements. Martens and the fisher have high metabolic rates, have large spatial requirements, have high surface area to volume ratios for animals that often inhabit high latitudes, and often require among the largest home range areas per unit body weight of any group of mammals. Resulting from these unique life history characteristics, this genus is particularly sensitive to human influences on their habitats, including habitat loss, stand-scale simplification of forest structure via some forms of logging, and landscape-scale effects of habitat fragmentation. Given their strong associations with structural complexity in forests, martens and the fisher are often considered as useful barometers of forest health and have been used as ecological indicators, flagship, and umbrella species in different parts of the world. Thus, efforts to successfully conserve and manage martens and fishers are associated with the ecological fates of other forest dependent species and can greatly influence ecosystem integrity within forests that are increasingly shared among wildlife and humans. We have made great strides in our fundamental understanding of how animals with these unique life history traits perceive and utilize habitats, respond to habitat change, and how their populations function and perform under different forms of human management and mismanagement. This knowledge enhances our basic understanding of all species of Martes and will help us to achieve the goal of conserving viable populations and representative distributions of the world’s Martes, their habitats, and associated ecological communities in our new millennium.
This guidebook has been prepared to help forest resource managers plan, prescribe, and implement sound forest practices that comply with the British Columbia Forest Practices Code. The information provided is to help users exercise professional judgment in developing site-specific management strategies and prescriptions to accommodate resource management objectives in the Prince George Forest Region. The first section of the guidebook covers the legislative authority, background, definitions, and procedures for species selection, stocking (including maximum density for conifers), establishment, and free growing. It also includes a listing of the relevant sections of the Code. The second section includes criteria tables for regional forest establishment and information for determination of free growing. The third section contains background and support information, forest health charts, and free growing damage standards.
