This book was released on 2010 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project used dendrochronology to reconstruct the history of mountain pine beetle (Dendroctonous ponderosae Hopkins) outbreaks over the last two centuries and to describe the relationship of outbreaks to varying climate conditions and fire history. The history of mountain pine beetle outbreaks was reconstructed from increment cores and basal disks collected from 85 stands across British Columbia and Alberta. Using aerial survey data, dendrochronological software was calibrated to detect growth releases that could be attributed to beetle outbreaks. Relationships between beetle outbreaks and climate variability were assessed using instrumental weather data, modelled climate data, and historical reconstructions of climate from tree-ring data. Relationships between the occurrence of beetle outbreaks and fire history were undertaken using several approaches in dendrochronology.--Document.

This book was released on 2006 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian government announced the Mountain Pine Beetle Initiative (MPBI) in 2002 to address the socio-economic and ecological consequences of an epidemic of mountain pine beetle (Dendroctonus ponderosae Hopkins). The objective of this study was to establish baseline information on the ecological characteristics that occur at different stages of succession, resulting from mountain pine beetle disturbance at different time intervals. Key issues addressed by this study were: the post-beetle ecological character of stands; the ecological legacies that should be sought post-beetle; maintenance of ecological integrity in beetle-damaged landscapes; and the impacts of beetles on regeneration. This paper presents a study of stand conditions following two historic mountain pine beetle outbreaks events in the 1940s and 1980s. The study quantified structural and species composition of stands at different stages of succession (25 years and 65 years), and quantified the differences that occur in forest development between stands with and without disturbance by the beetle. It concludes with several recommendations for management of post-disturbance landscapes.

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.
Download or read book Using Reconstructed Outbreak Histories of Mountain Pine Beetle Fire and Climate to Predict the Risk of Future Outbreaks written by Kathy J. Lewis and published by . This book was released on 2008 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae) is a native bark beetle of forests in BC, and there is documented evidence of outbreaks dating back to 1910. The current outbreak is substantially larger than past documented outbreaks, but the temporal scale of landscape-level forest change is much longer than the limited scope of recorded history. It is possible that the scale of management-induced changes to forest structure through fire suppression and forestry practices, and the mounting evidence of a changing climate, have contributed to an outbreak that is well outside the natural range of variation. The purpose of this project is to determine the magnitude and synchrony of historical beetle outbreaks in sub-boreal forests of central BC, and to relate those with climate factors and changes in fire regimes. Our focus is on the north-central part of BC, in areas that in the past have been less conducive to large scale mountain pine beetle outbreaks and less influenced by fire suppression, to determine whether or not the current outbreak in this area is due to the enormous population build-up alone, or whether changes in climate and/or fire regime have played a role. Using dendroecological methods, we have successfully reconstructed multiple mountain pine beetle outbreaks and calibrated our detection methods based on historical survey information. Our investigation of climate/outbreak relationships is underway and suggests that the timing of outbreaks in this area can be linked to periods of favourable climate for mountain pine beetle population growth.
Download or read book British Columbia in Flames written by Claudia Cornwall and published by Harbour Publishing. This book was released on 2020-09-19 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like many British Columbians in 2017, Claudia Cornwall found herself glued to the news about the disastrous wildfires across the province. Her worry was personal: her cabin at Sheridan Lake had been in the family for sixty years and was now in danger of destruction. Cornwall, a long-time writer, was stricken not just by her own experience, but by the many moving stories she came across about the fires—so she began collecting them. She met with people from BC communities of Sheridan Lake, Ashcroft, Cache Creek, 16 Mile House, Lac La Hache, Quesnel, Williams Lake, Hanceville-Riske Creek and Clinton. She hoped to be a conduit for the voices she heard—for those who fought the fires raging around them, those who were evacuated and displaced, and those who could do nothing but watch as their homes burned. She conducted over fifty hours of interviews with ranchers, cottagers, Indigenous residents, RCMP officers, evacuees, store and resort owners, search and rescue volunteers, firefighters and local government officials. Presented in British Columbia in Flames are stories that illustrate the importance of community. During the 2017 wildfires, people looked after strangers who had no place to go. They shared information. They helped each other rescue and shelter animals. They kept stores open day and night to supply gas, food and comfort to evacuees. This memoir, at once journalistic and deeply personal, highlights the strength with which BC communities can and will come together to face a terrifying force of nature.

This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: In western Canada, the operational risk rating system for mountain pine beetle is based on biological knowledge gained from a rich legacy of stand-scale field studies. Owing to the large spatial and temporal extents of the current epidemic, new research into large-area mountain pine beetle processes has revealed further insights into the landscape-scale characteristics of beetle infested forests. This research evaluates the potential for this new knowledge to augment an established system for rating the short-term risk of tree mortality in a stand due to mountain pine beetle.--Publisher's website.

Download or read book Detecting and Mapping Mountain Pine Beetle Red attack Damage with SPOT 5 10 m Multispectral Imagery written by Joanne White and published by . This book was released on 2006 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect of mature pine forests in western North America. From a forest management perspective, estimates of the location and extent of mountain pine beetle red-attack are critical; however, the degree of precision required for these estimates varies according to the management objective under consideration and the nature of the mountain pine beetle infestation. This report describes a study to explore the potential of single-date SPOT multispectral imagery to detect and map mountain pine beetle red-attack damage in an area with relatively low infestation levels using an automated classification procedure. In doing so, issues unique to SPOT, and the potential offered by the higher spatial resolution of SPOT compared with Landsat, could be identified. The viability of SPOT as an alternative data source to Landsat could then be assessed.

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. Using an established modelling framework, the authors of this report conducted a scenario analysis exercise designed to explore opportunities to mitigate the ecological and economic impacts of mountain pine beetle (MPB) salvage for two possible outbreak severity levels in Canfor's Tree Farm License (TFL) 48 in northeastern British Columbia. This data was used to address the following questions: 1) What are the potential short and long-term impacts of different levels of MPB attack for indicators of sustainable forest management in northeastern British Columbia?; and 2) Assuming a reduction in landscape-level ecological and economic stocks, what management options are available that will maintain a profitable harvesting profile while sustaining ecological indicators? Additionally, results from the analysis were evaluated in the context of a range of ecological and economic indicators.--Includes text from Government of Canada publications site and from document.
