Modeling Natural Regeneration Following Mountain Pine Beetle Attacks in the Southern and Central Interior of British Columbia by Valerie M. LeMay Pdf

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.

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.

Forest Health and Mortality of Advance Regeneration Following Canopy Tree Mortality Caused by the Mountain Pine Beetle by Kathy J. Lewis Pdf

"British Columbia is amid the largest recorded mountain pine beetle outbreak in North American history. To minimize timber losses, large-scale salvage operations are underway to utilize the merchantable pine. However, large-scale salvage operations can have negative impacts on a variety of forest values, including the potential to diminish mid-term timber supply opportunities. One option is to reserve stands with adequate advance regeneration for the mid-term timber supply. Another option is to salvage harvest dead trees in a way that protects the advanced regeneration. However, the health, vigour, form, and mortality rate of advance regeneration, through time, has not been well studied. To incorporate these stands into timber supply analyses and subsequent management decisions regarding reservation, mortality and forest health factors must be evaluated. We assessed the forest health of 90 residual stands over a range of stand types with varying lengths of time since attack by mountain pine beetle (MPB). Analysis of the forest health survey data showed that current damage from forest health agents was relatively low. Physical damage was the most common issue, but even in that case, the incidence ranged from

The Mountain Pine Beetle by Pacific Forestry Centre,Mountain Pine Beetle Initiative (Canada) Pdf

"This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

Natural Regeneration in Partial Cuts and Mature Forests After Mountain Pine Beetle Infestation in the West Chilcotin by Nola Marie Daintith,M. J. Waterhouse Pdf

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.

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.

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.

Historic Influence of the Mountain Pine Beetle on Stand Dynamics in Canada's Rocky Mountain Parks by Pamela Dykstra,T. F. Braumandl,Hawkes, B. C. (Brad C.),Pacific Forestry Centre Pdf

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.
