This book was released on 2008 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. The purpose of this report is to identify and characterize the fungal species that may potentially damage wood and decrease its market values. It focuses on the characterization of 40 different basidiomycetous fungi that were isolated form 12 different sites across British Columbia. Fungi were isolated from mountain pine beetle-infested lodgepole pine trees in green, red, and grey stages from each of the 12 sites.--Includes text from Government of Canada publications site and from document.

Book Synopsis Mountain Pine Beetle-killed Trees as Snags in Black Hills Ponderosa Pine Stands by : J. M. Schmid
Download or read book Mountain Pine Beetle-killed Trees as Snags in Black Hills Ponderosa Pine Stands written by J. M. Schmid and published by . This book was released on 2009 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain pine beetle-killed ponderosa pine trees in three stands of different stocking levels near Bear Mountain in the Black Hills National Forest were surveyed over a 5-year period to determine how long they persisted as unbroken snags. Rate of breakage varied during the first 5 years after MPB infestation: only one tree broke during the first 2 years in the three stands; breakage increased during the third year; the highest percentage of snags broke during the fourth year; and 10% to 14% broke in the fifth year. Cumulatively, snag breakage was 76%, 91%, and 95% in a GSL 80/90, GSL 100/110, and unmanaged stand, respectively. On average, 56% of the snags broke below 25 ft. The rate and height of breakage in mountain pine beetle-killed trees indicates that they are unlikely to persist as suitable snags for more than 5 to 10 years after infestation.
Book Synopsis Change in Wood Quality and Fall Rate of Trees Up to Ten Years After Death from Mountain Pine Beetle by : Kathy J. Lewis
Download or read book Change in Wood Quality and Fall Rate of Trees Up to Ten Years After Death from Mountain Pine Beetle written by Kathy J. Lewis and published by . This book was released on 2009 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the history of mountain pine beetle (Dendroctonous ponderosae Hopk.) outbreaks in British Columbia, including the outbreak in the mid 1980s that affected timber supply in the Quesnel Timber Supply Area, little was known about the post-mortality rate of deterioration of wood quality and quantity, and the rate of change in stand structure due to fall of dead trees. This study used dendrochronology to crossdate pine killed by mountain pine beetle to determine the exact year of mortality and to characterize decay and degradation in factors of wood quality and quantity over time.--Includes text from document.

Book Synopsis Assessing the Shelf Life Attributes of Mountain Pine Beetle-killed Trees by : S. Magnussen
Download or read book Assessing the Shelf Life Attributes of Mountain Pine Beetle-killed Trees written by S. Magnussen and published by . This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Growth of Ponderosa Pine Stands in Relation to Mountain Pine Beetle Susceptibility by :
Download or read book Growth of Ponderosa Pine Stands in Relation to Mountain Pine Beetle Susceptibility written by and published by . This book was released on 1999 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten-year diameter and basal area growth were determined for partially cut stands at 4 locations. Average diameters in the partially cut plots generally increased by 1 inch or more, while average diameter in the uncut controls increased by 0.9 inches or less. Individual tree growth is discussed in relation to potential susceptibility to mountain pine beetle infestation. Basal area increases ranged from 0.9 to 1.9 ft2/acre/ yr in partially cut plots, while basal area increases in the control plots ranged from 0.4 to 1.4 ft2/acre/yr. Endemic mountain pine beetle infestations and snow breakage accounted for most of the mortality on the plots, which decreased the residual basal area and basal area growth. Increases in basal area are used to estimate the length of time required for various stand densities to reach the susceptibility thresholds for mountain pine beetle infestation. Stand marking may influence future susceptibility to beetle infestations.

Book Synopsis Ponderosa Pine Mortality Resulting from a Mountain Pine Beetle Outbreak by : William F. McCambridge
Download or read book Ponderosa Pine Mortality Resulting from a Mountain Pine Beetle Outbreak written by William F. McCambridge and published by . This book was released on 1982 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1965 to 1978, mountain pine beetles killed 25% of the pines taller than 4.5 feet in a study area in north-central Colorado. Average basal area was reduced from 92 to 58 square feet per acre. Mortality increased with tree diameter up to about 9 inches d.b.h. Larger trees appeared to be killed at random. Mortality was directly related to number of trees per acre and presence of dwarf mistletoe, but not to site index, elevation, and percent Douglas-fir in the stand.
Book Synopsis Mountain Pine Beetle Attack in Ponderosa Pine: Comparing Methods for Rating Susceptibility by : David C. Chojnacky
Download or read book Mountain Pine Beetle Attack in Ponderosa Pine: Comparing Methods for Rating Susceptibility written by David C. Chojnacky and published by . This book was released on 2000 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two empirical methods for rating susceptibility of mountain pine beetle attack in ponderosa pine were evaluated. The methods were compared to stand data modeled to objectively rate each sampled stand for susceptibly to bark-beetle attack. Data on bark-beetle attacks, from a survey of 45 sites throughout the Colorado Plateau, were modeled using logistic regression to estimate the probability of attack on individual trees from tree and stand variables. The logistic model allowed flexibility to easily scale results up to a stand level for comparison to the empirical methods. The empirical method, developed by Munson and Anhold, most closely correlated to the logistic regression results. However, the Munson/Anhold method rated all 45 study sites as either moderately or highly susceptible to bark-beetle attack, which raises concern about its lack of sensitivity. Future work on evaluating risk of bark-beetle impact should consider more than stand characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: "This research focuses on studying the heat tolerance of sap-rot and heart-rot fungi found in beetle-killed wood. Specifically, the authors evaluate the 56/30 schedule and other temperature/time combinations. They also investigate whether slow air-drying increased the heat tolerance of the fungi. The generated data are expected to fill an important science gap on the fungi found in beetle-affected trees."--Document.
