Microclimate Studies in Mountain Pine Beetle-damaged Silvicultural Systems on the Chilcotin Plateau by Robert Matthew Sagar,M. J. Waterhouse Pdf

The objectives of this study were to: 1. compare the key environmental variables between blocks (elevational effect) and treatments (clearcut and irregular group shelterwood with whole-tree harvesting partial cut), and between microsites within partial cut openings (north and south edges and centre); and 2. examine temporal changes occurring to environmental variables in the context of the changing biological environment. This document includes an introduction, methods, results and discussion, and a summary.--Includes text from document.

Natural Regeneration in Partial Cuts and Mature Forests After Mountain Pine Beetle Infestation in the West Chilcotin by Nola Marie Daintith,M. J. Waterhouse Pdf

The Itcha-Ilgachuz Research Project was initiated in the west Chilcotin region of central British Columbia to test variants of group selection and irregular group shelterwood silvicultural systems for managing lodgepole pine (Pinus contorta var. latifolia) forests for timber and northern caribou (Rangifer tarandus caribou Gmelin, northern ecotype) winter habitat. The results presented in this report are from three assessments that have been completed since the start of the mountain pine beetle outbreak, and are provided in context with the results from the earlier natural regeneration study. The results provide insight into how successfully the study sites and surrounding forests, which have sustained variable levels of mortality, regenerate naturally.--Includes text from document.

A Silvicultural Assessment of 10 Lodgepole Pine Stands After Partial Cutting to Reduce Susceptibility to Mountain Pine Beetle by Roger J. Whitehead Pdf

Over the past 15 years, selective cutting prescriptions have been applied by forest operations in southeastern British Columbia as part of a strategy to reduce landscape-level susceptibility to damage from mountain pine beetle outbreaks. The prescriptions have been applied in stands where maintenance of some mature forest cover is needed to meet management objectives for viewscapes, recreation and habitat or to hold some pine volume during periods of rising beetle activity until it is required or available for harvest. In this study, we examined 10 of these sites 5 to 14 years after harvest, and determined current stand composition and structure from direct sampling and pre- and post-treatment stand characteristics from stand reconstruction. We then related these characteristics to original treatment specifications; the volume removed during harvest and remaining on site after treatment; subsequent losses to wind, snow or bark beetle damage; current stocking status; radial growth rates of residual overstorey trees; and the nature of fuel complexes created and effects of treatment on potential fire behaviour.

Mountain Pine Beetle Symposium by Pacific Forestry Centre,Mountain Pine Beetle Initiative (Canada) Pdf

The S2Mountain Pine Beetle Symposium: Challenges and SolutionsS3 was held in Kelowna, British Columbia, Canada on October 30-31, 2003. This meeting was organized by Natural Resources Canada, Canadian Forest Service, Pacific Forestry Centre and funded through the Government of Canada Mountain Pine Beetle Initiative. Approximately 250 people representing the forest industry, consultants, universities, provincial and federal government agencies, First Nations, and the general public, from both Canada and the United States attended the meeting. Thirty presentations were given describing the current mountain pine beetle situation (in British Columbia, Alberta and the western United States) and its management and economic implications. Researchers presented the latest information on remote sensing, decision support systems, impacts on stand dynamics and wildlife, phytosanitary risks, climate change effects and preventive management as they relate to mountain pine beetle.

Mountain Pine Beetle and Salvage Harvesting Influence on Small Stream Riparian Zones by John F. Rex Pdf

This paper reports on the investigation of the influence of the mountain pine beetle infestation and salvage harvesting on small stream and riparian zone ecological function, shade, and temperature. Small streams (less than a 2 m bankfull width) were selected because they are the most prominent stream type within a watershed and they determine many ecological characteristics of larger downstream channels.--Document.

Historical Frequency, Intensity and Extent of Mountain Pine Beetle Disturbance in British Columbia by René I. Alfaro Pdf

This project used dendrochronology to reconstruct the history of mountain pine beetle (Dendroctonous ponderosae Hopkins) outbreaks over the last two centuries and to describe the relationship of outbreaks to varying climate conditions and fire history. The history of mountain pine beetle outbreaks was reconstructed from increment cores and basal disks collected from 85 stands across British Columbia and Alberta. Using aerial survey data, dendrochronological software was calibrated to detect growth releases that could be attributed to beetle outbreaks. Relationships between beetle outbreaks and climate variability were assessed using instrumental weather data, modelled climate data, and historical reconstructions of climate from tree-ring data. Relationships between the occurrence of beetle outbreaks and fire history were undertaken using several approaches in dendrochronology.--Document.

A Synthesis of the Hydrological Consequences of Large-scale Mountain Pine Beetle Disturbance by Markus Schnorbus Pdf

The current synthesis is a review of research examining the effects of large-scale mountain pine beetle (MPB)-related disturbance conducted predominantly over the past five years. The emphasis is on research that explicitly examines the impact of beetle kill (or biotic disturbance in general) and the cumulative effects of large scale salvage harvesting operations in response to beetle kill. In general, forest disturbance has been found to increase snow accumulation and melt, reduce interception loss and evaporation, and increase runoff and stream flow.--Document.

Mountain Pine Beetle by Fred L. Bunnell,L. L. Kremsater,Isabelle Houde Pdf

This document provides a synthesis of recently completed studies to assess the ecological consequences of forest management after attack by mountain pine beetle or other large-scale disturbances. Studies are assessed for their contributions to gaps in knowledge previously identified in the Mountain Pine Beetle Initiative Working Paper "Evaluating effects of large scale salvage logging for mountain pine beetle on terrestrial and aquatic vertebrates," which was published in 2004. This report focuses on studies developed through the federal Mountain Pine Beetle Initiative, the federal Mountain Pine Beetle Program, and the complementary BC Forest Science Program. Relevant information from other jurisdictions is sometimes included to augment those studies. Topics examined are: the impacts of beetle kill and salvage operations on habitat attributes; the impacts of beetle kill and salvage operations on attendant processes, such as snag fall rates, light interception, and snow accumulation; and the wildlife response to large-scale beetle outbreaks and management strategies. For each of these three topics, we provide a summary of: research to date; pertinent findings to date; and gaps in research.

Environmental Effects on Host Selection and Dispersal of Mountain Pine Beetle by Mary Lynn Reid Pdf

This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. It summarizes the results of a study on the landscape variation in lodgepole pine constitutive defences, primarily measured as resin production, but also as phloem monoterpene concentration. The response of pioneer mountain pine beetles to those defences is reviewed, measured by experimentally placing beetles on trees and by attacks of free-flying beetles; effects of beetle quality (size, condition) on the beetles' responses are also examined. Finally, the results on the dispersal of mountain pine beetles through a mature lodgepole pine stand and a burned stand are presented.--Includes text from Government of Canada publications site and from document.
