Available in PDF, EPUB and Kindle. Book excerpt: Mountain pine beetle (MPB)-killed wood remaining on the landscape is predicted to release significant amounts of carbon to the atmosphere as it decays. A lack of field-based wood decomposition data for validating simulation models reduces certainty in such predictions. Using a chronosequence approach, I quantified decomposition of MPB-killed wood to improve decay rate parameters. Changes in carbon density over time and climatic variability showed distinct patterns for bole position categories. Snag carbon density was similar to that of live lodgepole pine, and did not change considerably with time or climatic influences. Decay in suspended boles increased with summer precipitation, but declined with increasing summer temperature, suggesting decay in elevated boles is moisture-limited on warmer sites. Down boles decayed four times faster with increasing proximity to the soil than suspended boles, but did not clearly reflect climatic influences. Position of dead boles appears more important for wood decay than previously thought. --Leaf ii.

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 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 Spatiotemporal Associations Between Forests Impacted by Mountain Pine Beetle and Adjacent Replantings Impacted by Warren Root Collar Weevil by : Matthew D. Klingenberg

Klingenberg and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A concern to reforestation efforts following the recent outbreak of mountain pine beetle, Dendroctonus ponderosae Hopkins, is the migration of the below-ground herbivore Warren root collar weevil, Hylobius warreni Wood, from stands with a high percentage (>80%) of mature, dead lodgepole pine, Pinus contorta var latifolia Dougl. ex. Loud., into adjacent young, replanted stands, resulting in significant levels of mortality to juvenile trees. The effects of the spatial patterns of salvage harvesting following outbreaks of mountain pine beetle on the development of Warren root collar weevil pressure in neighbouring, regenerating stands was examined in young lodgepole pine stands in the central interior of British Columbia, Canada. Gradients of tree mortality caused by feeding of Warren root collar weevils were observed and found to be dependent on characteristics of the adjacent, unsalvaged stands. Mortality was exacerbated by high components of dead pine in these stands, and became worse over time. To investigate whether reduced host availability is a potential causal factor explaining such patterns, I constructed three research plots consisting of combinations of live tree, dead tree and mixed (i.e., live and dead) tree habitats and observed dispersal patterns of labeled insects. Weevils were more likely to be captured close to the release location in the mixed and live habitats vs. the dead habitat. Movement rate was high in the dead habitat compared with the live and mixed habitats. In the plot with the dead habitat adjacent to the location of release, the probability of capture was lower, but movement rate and dispersal distance were greater, indicating that Warren root collar weevils will disperse out of a habitat with dead trees into a habitat with live trees. Implications to reforestation strategies following savage harvesting are discussed.--P.ii.

Book Synopsis Salvage Harvest Effects on Advance Tree Regeneration, Soil Nitrogen, and Fuels Following Mountain Pine Beetle Outbreak in Lodgepole Pine by : Jacob M. Griffin
Download or read book Salvage Harvest Effects on Advance Tree Regeneration, Soil Nitrogen, and Fuels Following Mountain Pine Beetle Outbreak in Lodgepole Pine written by Jacob M. Griffin and published by . This book was released on 2013 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extent and severity of recent native bark beetle (Dendroctonae) outbreaks in western North America have created a pressing need for forest managers to understand potential consequences of post-disturbance management. For example, post-outbreak timber harvest (i.e., salvage harvest) could alter future forest development, productivity and susceptibility to subsequent disturbance. To assess the potential for such consequences, we measured first-year effects of post-outbreak timber harvest on tree regeneration, soil nitrogen (N) availability and fuels by using a paired and replicated before?after-control-impact (BACI) experimental design with eight pairs of 0.25-ha plots in beetle-killed lodgepole pine (Pinus contorta var. latifolia) in Greater Yellowstone (Wyoming, USA). Post-outbreak timber harvest reduced total (live + dead) lodgepole pine basal area by 90%. Total sapling density (advance regeneration) declined by about 50% following harvest, with tall (30?140 cm) saplings declining most, but mean post-harvest sapling density still exceeded 1600 stems ha^?1. Relative species density was unaffected and remained dominated by lodgepole pine. Soil temperature at the litter?soil interface was warmer during summer in harvested stands, and soil View the MathML source concentration increased with harvest relative to untreated plots. Soil View the MathML source concentration and resin bag N accumulation increased through time in all beetle-killed plots and were not affected by harvest. Following harvest, dead woody surface fuels in all size categories doubled, and canopy fuel load and canopy bulk density both were reduced; dead fuel depth, duff depth, and canopy base height did not differ between untreated and harvested plots. Harvest did reduce canopy fuels, but the natural progression of needle shedding after beetle-kill accounted for 25?40% of this total canopy fuel reduction. Salvage harvest seems unlikely to alter post-outbreak successional trajectories in these lodgepole pine forests. However, the altered fuel complex (immediate increase in dead woody surface fuels and expected long-term reduction in large-diameter fuels) in harvested plots could cause subsequent fire behavior and effects to differ between harvested and untreated stands.

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 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.
