A Framework for Documenting the Effects of the Mountain Pine Beetle Outbreak in Sub-boreal Forests of Northern British Columbia (E.P. 1369) by Ben Heemskerk,C. DeLong,Tanya Milner Pdf

"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.

Mountain Pine Beetle Impacts on Channel Morphology and Woody Debris in Forested Landscapes by Marwan Hassan Pdf

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 (MPB) epidemic. The objective of this report was to determine watershed-scale impacts of mountain pine beetles by comparing channel conditions and the woody debris budget in watersheds infested by the MPB with those from similar old-growth forests with pre-infestation channel and riparian data. The use of a woody debris budget directly links large-scale lodgepole pine mortality to stream challen and piparian processes and conditions at the landscape level. Eighteen watersheds in the Sub-Boreal Spruce and Sub-Boreal--Pine Spruce biogeoclimatic zones were considered. The results are used to generate regionally and locally relevant best management practices that will guide operational planning in landscapes impacted by the MPB.--Includes text from Government of Canada publications site and from document.

Using Reconstructed Outbreak Histories of Mountain Pine Beetle, Fire and Climate to Predict the Risk of Future Outbreaks by Kathy J. Lewis,Kate Hrinkevich Pdf

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.

Exploring Opportunities for Mitigating the Ecological Impacts of Current and Future Mountain Pine Beetle Outbreaks Through Improved Planning by Brad Seely Pdf

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.

Mountain Pine Beetle by Fred L. Bunnell,L. L. Kremsater,Isabelle Houde Pdf

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.

Evaluation of Risk Assessment of Mountain Pine Beetle Infestations by Caren C. Dymond Pdf

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. In this paper, an established decision support system was evaluated for operational use. Digital forest inventory and beetle-impact survey data were integrated in standard GIS software for rating susceptibility and risk of mountain pine beetle infestation. The beetle-impact data, collected over a three-year period, provided an opportunity to generate risk on a given year and compare it to attacks in the subsequent year.--Includes text from Government of Canada publications site and from document.

Exploring the Spatial-temporal Interaction of Mountain Pine Beetle Infestations by Colin Robertson Pdf

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. It examines mountain pine beetle (Dendroctonus ponderosae Hopkins) dispersal processes, which drive the spatial and temporal development of outbreaks. Understanding these processes is important for modelling future infestations and guiding forest management decisions. In this study, the spatial patterns of red- and green-attacked trees were used to characterize the spatial-temporal nature of dispersal. Research aims were to detect evidence of dispersal based on the distance and direction between red- and green-attacked tree clusters, determine how dispersal patterns change at different stages of infestation, and to detect landscape variables influencing the observed dispersal patterns. Variables explored included Biogeoclimatic ecosystem classification (BEC), topography, and the local population of susceptible hosts.--Includes text from Government of Canada publications site and from document.

Mountain Pine Beetle Range Expansion by Katherine Patricia Bleiker,Allan Carroll,G. D. Smith,Mountain Pine Beetle Initiative (Canada) Pdf

For this report the authors investigated whether an endemic niche exists for the mountain pine beetle (MPB) in north-western Alberta, a region east of the Rocky Mountains that was recently invaded by beetles. Their approach was to sample endemic or endemic-incipient MPB populations in the region in situ, including the assemblage of secondary bark beetles with which the MPB may interact. The objectives of this project were threefold: (i) determine the potential for MPB to persist at endemic levels east of the Rockies; (ii) if persistence is possible, determine the rate of population increase or decrease to assess the potential for eruptions and spread; and (iii) provide data to existing and emergent decision support tools to re-parameterize, where appropriate, to accommodate MPB dynamics in a new habitat.--Document.

Environmental Effects on Host Selection and Dispersal of Mountain Pine Beetle by Mary Lynn Reid Pdf

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. It summarizes the results of a study on the landscape variation in lodgepole pine constitutive defences, primarily measured as resin production, but also as phloem monoterpene concentration. The response of pioneer mountain pine beetles to those defences is reviewed, measured by experimentally placing beetles on trees and by attacks of free-flying beetles; effects of beetle quality (size, condition) on the beetles' responses are also examined. Finally, the results on the dispersal of mountain pine beetles through a mature lodgepole pine stand and a burned stand are presented.--Includes text from Government of Canada publications site and from document.

Mountain Pine Beetle Survey in the Peace Region of British Columbia and Adjacent Areas in Alberta by Kevin Pellow,Leo Unger,Gurp Thandi Pdf

The current mountain pine beetle (MPB) outbreak exceeds any recorded infestation and is considered a threat to pine species in the boreal and eastern Canadian forest ecosystems. Previous studies have shown that moderate weather and successful fire suppression create prime conditions for MPB growth, which is affecting novel forest habitat. From 2008 to 2010, the Canadian Forest Service (CFS) conducted late spring surveys of MPB infestations in the Peace Region of British Columbia to determine changes in population and infestation levels based on attack and brood densities in infested trees. During 2009 and 2010, similar data was collected by the Alberta Sustainable Resource Development (SRD) on post-winter MPB survival in north-central Alberta. Overwintering population success was determined based on two rating systems of R-values: the Canadian Forest Service Forest Insect and Disease Survey (FIDS) system of the CFS, and the SRD system. R-value was calculated by summing all live mountain pine beetles of various life stages for every plot. The British Columbia and Alberta survey data (the R-values) were combined to determine the distribution of overwintering population success. During 2009 and 2010, the overwintering MPB population success in the Peace Region of British Columbia and adjacent Alberta was based on interpolated maps of SRD ratings of infestations. For comparison, a map for each rating system was created from the 2010 surveys of British Columbia and Alberta.
