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.

Book Synopsis Modeling Natural Regeneration Following Mountain Pine Beetle Attacks in the Southern and Central Interior of British Columbia by : Valerie M. LeMay
Download or read book Modeling Natural Regeneration Following Mountain Pine Beetle Attacks in the Southern and Central Interior of British Columbia written by Valerie M. LeMay and published by . This book was released on 2007 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the federal Mountain Pine Beetle Program, research is being implemented to study the economic and ecological characteristics of mountain pine beetle-damaged stands in British Columbia and Alberta. Stand development projections following mountain pine beetle (Dendroctonus ponderosae) (MPB) attack will depend upon the ability to accurately project natural regeneration following attack. In this study, stand structure measured on affected stands shortly after attack was used to estimate the abundance and composition of natural regeneration a number of years following attack. Specific objectives were: to assess natural regeneration development in stands that have sustained mortality during current and/or previous MPB outbreaks; to develop a natural regeneration database for use in connection with the PrognosisBC growth and yield simulator; to use imputation techniques to extend the existing natural regeneration model to MPB-affected stands in the southern and central interior of the province; and to develop and enhance the software necessary to allow reasonable projections of MPB-affected stands.--Document.

Book Synopsis Temporal Composition and Structure of Post-beetle Lodgepole Pine Stands by : K. Runzer
Download or read book Temporal Composition and Structure of Post-beetle Lodgepole Pine Stands written by K. Runzer and published by . This book was released on 2008 with total page 80 pages. 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.

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 Lodgepole Pine Stands and Its Relation to Mountain Pine Beetle Susceptibility by : S. A. Mata
Download or read book Growth of Lodgepole Pine Stands and Its Relation to Mountain Pine Beetle Susceptibility written by S. A. Mata and published by . This book was released on 2003 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periodic diameter and basal area growth were determined for partially cut stands of lodgepole pine at five locations over approximately 10 year periods. After cutting, average diameters in the partially cut plots generally increased by 0.8 inches or more, while average diameter in the uncut controls increased by 0.6 inches or less. Diameter growth in the partially cut plots was generally significantly greater than diameter growth in the controls. Individual tree growth is discussed in relation to potential susceptibility to mountain pine beetle infestation. Basal area decreased in three of the four GSL (growing stock level) 40 stands because of windthrow. Basal area generally increased >1.0 ft 2 / acre/year in partially cut plots except in the GSL 40 stands with substantial windthrow and one GSL 100 with an Armillaria infection pocket. Basal area increases in the control plots ranged from 0.2 to 1.1 ft 2 /acre/year, although the one control with a BA growth rate of 1.1 ft 2 /acre/year had a relatively low initial BA. Data from the stands are employed in the susceptibility rating methods of Amman et al.(1977), Shore and Safranyik (1992),and Anhold et al. (1996 to determine stand susceptibility and the results discussed in terms of general applicability of these methods to partially cut stands. Basal area growth is used to estimate the length of time required for various stand densities to reach specific susceptibility thresholds for mountain pine beetle infestation. Several of the GSL 40 stands are not projected to reach the susceptibility thresholds in 100 years because of windthrow. Barring mortality 1%,GSL 80 stands are estimated to reach the basal area threshold of 120 ft 2 per acre in

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.
Book Synopsis Modelling the Distribution of Advance Regeneration in Lodgepole Pine Stands in the Central Interior of British Columbia by : Darin Warren Brooks
Download or read book Modelling the Distribution of Advance Regeneration in Lodgepole Pine Stands in the Central Interior of British Columbia written by Darin Warren Brooks and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The recent mountain-pine beetle outbreak in the Central Interior of British Columbia is leaving unsalvaged stands with minimal silvicultural treatment, raising questions about their ability to regenerate and the implications of this uncertainty to future timber supply and habitat values. No system currently exists to predict, on a landscape level, which pine stands will have adequate stocking of advance regeneration suitable for release upon canopy death. My research takes a ground-truthed, landscape-level approach to modelling, predicting, mapping, and prioritizing stands for salvage or rehabilitation. The resulting model, derived from recursive partitioning of data from 964 sample plots, created a landscape level output with a predictive accuracy of 78%. Across the Sub-Boreal Spruce study area, I estimate that 58% of mature pine-leading stands (approximately 840,000 ha) are likely or very likely to be stocked with at least 600 stems/ha of living understory trees."--Leaf ii.

This book was released on 2008 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report outlines the objectives, study design, methods of data collection, and other details relevant to the establishment of Experimental Project (EP) 1369: A Framework for Documenting the Effects of the Mountain Pine Beetle in Sub-boreal Forests of Northern British Columbia. In 1995 through 1997, 48 plots were established in mature pine leading stands affected by mountain pine beetle (MPB) (38 plots) and MPB followed by wildfire (10 plots). All plots will remain unharvested, and are designed to examine ecological changes subsequent to these disturbances. The information from these plots will inform science on what ecological changes result from these disturbances in the sub-boreal forest landscape, and will provide critical information (such as growth rate of live understorey) to land managers."--Document.
Book Synopsis A Silvicultural Assessment of 10 Lodgepole Pine Stands After Partial Cutting to Reduce Susceptibility to Mountain Pine Beetle by : Roger J. Whitehead
Download or read book A Silvicultural Assessment of 10 Lodgepole Pine Stands After Partial Cutting to Reduce Susceptibility to Mountain Pine Beetle written by Roger J. Whitehead and published by . 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.
