This book was released on 2015 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "A recent survey of mountain pine beetle (MPB) attack in mature and immature pine leading stands indicated that attack rate was a function of tree size, age and stand density. However, the temporal dynamics of MPB attack in mature and immature stands, as well as the release of the regeneration layer or secondary structure under a dying canopy, are poorly understood. The primary objectives of this study were to i) investigate temporal and spatial aspects of MPB attack, ii) investigate regeneration dynamics (mortality and growth) of post-beetle attack, iii) model growth and yield with actual mortality and regeneration metrics, iv) describe economic opportunities of harvest scheduling with respect to post-MPB stand structure and v) develop improved management and regeneration options."--Document.

Book excerpt: 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.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecological disturbance from wildfire (2004) on ~10,000 hectares of forests near the Kenny Dam presented a unique opportunity to study the natural and artificial regeneration in burned mountain pine beetle (Dendroctonus ponderosae Hopkins) infested stands in north-central British Columbia. Mountain pine beetle (MPB) has been documented as a natural disturbance agent that may precede wildfire in lodgepole pine forests (Pinus contorta var. latifolia). The objectives of this thesis were to i) characterize lodgepole pine regeneration and related micro-site conditions associated with wildfire, ii) identify limitations for germination, survival and recruitment of natural and artificial regeneration in relation to site moisture, fire severity, and vegetative competition, and iii) provide guidance on local operational management of MPB-killed stands.

This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lodgepole pine (Pinus contorta) forests of the Intermountain West are currently experiencing a widespread epidemic of the mountain pine beetle (Dendroctonus ponderosae), due in part to climate change. A large proportion of mature lodgepole trees have died, with largely unknown implications for forest-dwelling species. A critical question is to determine which alternative stand types will best support forest-dependent wildlife species prior to mature lodgepole regeneration. Our objectives were to examine the relative abundance and diversity of birds and small mammals across a gradient of patch sizes of spruce-fir and previously logged (young) lodgepole stands within a matrix of beetle-killed lodgepole forest. During 2010-2011, we conducted point counts in each stand type across available patch sizes. Species assemblages differed significantly between stand types and among patch sizes. Avian species that forage and nest in lower forest strata and fly-catching species were more abundant in young lodgepole stands. Aerial flycatcher abundance decreased with increasing patch size. Members of the Piciform family, corvids, secondary cavity nesters, and species that forage in upper canopy were more abundant in spruce-fir stands. The largest patches of spruce-fir supported the greatest avian diversity. Stand types differed greatly in small mammal community composition. Southern red-backed voles (Clethrionomys gapperi) had greater likelihood of occurrence in spruce-fir stands, whereas least chipmunks (Tamias minimus) and deer mice (Peromyscus maniculatus) had greater likelihood of occurrence in young lodgepole stands. Small mammal densities did not vary with patch size in either stand type. Small mammal diversity was approximately equal between the stand types; however, species assemblages were very different between the stand types. Most of the rarely encountered species were found in spruce-fir patches, whereas generalist species such as deer mice and chipmunks were found almost exclusively in young lodgepole. Our results provide a foundation for managers evaluating management actions influencing the size and distribution of forest stands in post-bark beetle landscapes.

This book was released on 1985 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect that attacks lodgepole pine (Pinus contorta Dougl.), a species valued for multiple uses throughtout North America. The effective residual life of carbaryl, applied as a 2 percent suspension of Sevimol to the bark of lodgepole pine to prevent attack by mountain pine beetle, was evaluated near Dillon, Colorado. Trees (9,568) treated in 1982 under operational conditions were used to assess the efficacy of the treatment for one and two beetle flight periods after insecticide application. Estimated mortality of untreated trees was 0.91 percent compared with 0.074 percent for trees treated 16 months earlier with carbaryl. Residues of carbaryl were estimated at 359 ppm 16 months after application. When exposed to intense beetle pressure, bolts from trees treated 13 months earlier suffered fewer attacks and had shorter mean egg gallery length than did bolts from untreated trees; bolts from trees sprayed 3 months earlier suffered no attacks. Apparently a 2 percent suspension of carbaryl applied to the bole of lodgepole pine was effective in protecting lodgepole pine from mountain pine beetle for the flight period 3 months after application and even provided protection for a second flight period 16 months after treatment. I The results suggest that protection cost and I insecticide use could be reduced by 50 percent during a 4-year outbreak.
