Assessing the Shelf Life Attributes of Mountain Pine Beetle-killed Trees by S. Magnussen,David S. Harrison Pdf

In 2006, a total of 360 lodgepole pine trees were destructively sampled from 45 sites that had been killed by mountain pine beetle (Dendroctonous ponderosae Hopk.). The trees were sampled from the Sub Boreal Spruce (SBS) Biogeoclimatic zone within north central British Columbia. The trees were distributed evenly across the geographic areas as well as across a sample matrix that included three classes of time since death, three classes of diameter at breast height, and three classes of soil moisture regime. A previous report described the procedures used to the collect the data and summarized the data collected for each of the sample trees. The current study analyzes the data and presents a detailed assessment of the changes in the wood quality attributes of mountain pine beetle-killed trees that occur within 5 years since death.--Includes text from document.

Methodology to Assess Shelf Life Attributes of Mountain Pine Beetle-Killed Trees by David S. Harrison,Pacific Forestry Centre,Mountain Pine Beetle Initiative (Canada) Pdf

"A study took place near Quesnel, BC, in November, 2004, to test a sampling procedure designed to determine which attributes of beetle-killed lodgepole pine trees resulted in a reduction in lumber recovery and product value over time. Old grey-attack trees were destructively sampled, and sampled trees, discs and logs were analyzed. The test results provided preliminary information on variables pertaining to log and wood quality and quantity of beetle-killed timber within older grey-attack stands."--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.

Storing Beetle-killed Logs Under Snow to Reduce Losses After Mountain Pine Beetle Attack by Roger J. Whitehead,Joseph Nader,William Leroy Wagner,Canadian Wood Fibre Centre Pdf

To assess the potential to store beetle-killed logs under insulated snowpacks in British Columbia to preserve wood quality and maximize value recovery, we reviewed the literature and visited operations in eastern Canada, where the technique has been recently adapted to routine operations, and in Finland, where 3.5 million m3 of timber are stored under snow annually. We also visited storage terminals in Sweden where very large volumes of sawtimber have been stored since 2005. We identified three roles that cold storage could play in responding to the current mountain pine beetle outbreak: (1) where the outbreak is expanding rapidly and green-attack volume exceeds capacity of mills to process all logs prior to dispersal flight, cold storage can prevent development and dispersal of beetles before milling late in the season; (2) where significant value is lost between harvesting and processing due to checking after delivery to the mill, cold storage can maintain moisture content and extend the time frame for achieving higher economic recovery; and, (3) where there is an opportunity to store large volumes of quality logs, doing so for an extended period (more than one year) may help defer or moderate anticipated social, environmental and economic impacts in the areas most affected by the mountain pine beetle outbreak. We report on discussions with woodland and plant managers in British Columbia on how the technique might be adapted to western Canadian operations and possible impediments to implementation, and we present recommendations.

Evaluation of Risk Assessment of Mountain Pine Beetle Infestations by Caren C. Dymond 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. In this paper, an established decision support system was evaluated for operational use. Digital forest inventory and beetle-impact survey data were integrated in standard GIS software for rating susceptibility and risk of mountain pine beetle infestation. The beetle-impact data, collected over a three-year period, provided an opportunity to generate risk on a given year and compare it to attacks in the subsequent year.--Includes text from Government of Canada publications site and from document.

Impact of Mountain Pine Beetle Infestation and Salvage Harvesting on Seasonal Snow Melt and Runoff by Sarah Boon Pdf

"This study examines the impact of mountain pine beetle infestation on forest canopy structure on the Nechako Plateau, and the resulting impacts on snow accumulation and ablation under varied climatic conditions. Stand-scale results were used to drive a physically-based, distributed hydrological model of the Van Tine Creek watershed and assess watershed-scale hydrologic response to four harvesting/infestation scenarios."--Document.

Mountain Pine Beetle Infestations in Relation to Lodgepole Pine Diameters by Walter E. Cole,Gene D. Amman Pdf

Tree losses resulting from infestation by the mountain pine beetle (Dendroctonus ponderosae Hopkins) were measured in two stands of lodgepole pine (Pinus contorta Dougl.) where the beetle population had previously been epidemic. Measurement data showed that larger diameter trees were infested and killed first. Tree losses ranged from 1 percent of trees 4 inches (d.b.h.) to 87 percent of those 16 inches and greater d.b.h. Numbers of adult beetle emergence holes averaged 1.3 per square foot of bark area in trees 7 inches d.b.h. and 62 in trees 28 inches and greater d.b.h. The observations indicate that large infestations of mountain pine beetle depend on the presence of large diameter trees within a stand of lodgepole pine, thus implying that beetle population growth is food-limited.

Assessing the Influence of Time-since-death by Barbara Dalpke 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 (MPB) epidemic. It presents the results of pilot plant Kraft and mechanical pulping trials that were conducted to determine the influence of time-since-death (TSD) of (MPB)-killed lodgepole pine on pulping and pulp quality. Samples included trees of red, grey and late grey attack stages as well as unattacked trees; sample sites were established in three different biogeoclimatic subzones in British Columbia in order to account for natural variability. Prior to pulping, samples were tested for wood and fibre properties as well as chip quality. Kraft and thermomechanical (TMP) pulping parameters were monitored, pulp quality was determined, and sheet structure was evaluated by scanning electron microscopy.--Includes text from document.

Characteristics of Endemic-level Mountain Pine Beetle Populations in South-central Wyoming by Dale L. Bartos Pdf

This study was conducted to evaluate the dynamics of endemic populations of mountain pine beetle (Dendroctonus ponderosae Hopkins). In addition, we extended the geographical range of an existing data base recorded in Utah with similar data from Wyoming. This work was accomplished in lodgepole pine (Pinus contorta Dougl. Var. latifolia Engelm.) stands on the Medicine Bow National Forest in south-central Wyoming. Thirty-eight variable-radius paired plots (BAF 10) were measured during the summer of 1987. Host-tree condition and mountain pine beetle infestation characteristics were determined from currently and previously infested trees. Presence and severity of Armillaria root disease and stem pathogens was determined. Tree condition and infestation patterns were similar at this site to those found in earlier studies. Trees selected by endemic mountain pine beetle populations were infested with Comandra blister rust (Cronartium Comandra PK) and root disease (Armillaria spp.). Host-tree condition and mountain pine beetle infestation patterns recorded in this study parallel those identified earlier in Utah and will help land managers identify trees to cut to reduce stand hazard to mountain pine beetle infestation.
