The Economics of Salvage Harvesting and Reforestation in British Columbia's Mountain Pine Beetle-affected Forests by Brian Peter,Bryan Edward Cooper Bogdanski Pdf

In stands with significant mountain pine beetle (MPB) mortality, forest managers face a range of choices including clearcut harvesting, partial cutting, various rehabilitation strategies, and non-intervention. These choices involve many long-term costs, benefits, and risks, some of which can be assessed through economic analysis. After reviewing the context for this issue, the authors provided case studies that span the more likely stand-level problems faced by decision makers. All analyses were conducted from the perspective of the landowner (i.e., government) rather than the user of the resource (i.e., licensee). The insights from the case studies form a basis to answer the following core questions: Are some stand types better left unsalvaged? What economic/silvicultural assumptions produce higher stand values when salvaging is foregone? In areas that cannot be salvaged, is reforestation a profitable investment? Finally, does partial cutting make sense economically?--Document.

Forest Stewardship in the Context of Large-scale Salvage Operations by Marvin Alastair Eng,Larry Pedersen,British Columbia. Forest Science Program Pdf

All indications are that the current mountain pine beetle outbreak will have a significant impact on a large proportion of the pine forests in British Columbia (Eng et al. 2004). It is neither desirable nor possible to harvest all of the affected pine forests. Nonetheless, any increases beyond current harvest levels must carefully consider all forest values. This document provides recommendations to the Chief Forester about the conservation of all forest values during large-scale salvage operations: 1. At the landscape level, there should be little, to no, salvage harvesting in the noncontributing land base and, at the very least, what was originally planned under existing landscape-level plans should be left. 2. At the stand level, there should be no changes to the provisions made for riparian management areas and riparian reserve zones. As well, there should be no changes to the management of wildlife tree patches, wildlife habitat areas, and other fine-filter measures. Legacies of coarse woody debris should be left throughout the blocks. 3. To the extent possible, the area chosen for salvage should have the highest level of infestation and the highest proportion of pine. 4. The creation of large openings (> 1000 hectares) will be appropriate; however, the legacies of unharvested areas within the openings should increase in proportion to the increasing size of the opening (up to 25% in the case of 1000-hectare openings). Other related recommendations are made about access structures, adverse effects on peak flows and soil erosion, silviculture that might lessen future problems with mountain pine beetle outbreaks, fire risk at the wildland-urban interface, and monitoring programs.

Mountain Pine Beetle and Salvage Harvesting Influence on Small Stream Riparian Zones by John F. Rex Pdf

This paper reports on the investigation of the influence of the mountain pine beetle infestation and salvage harvesting on small stream and riparian zone ecological function, shade, and temperature. Small streams (less than a 2 m bankfull width) were selected because they are the most prominent stream type within a watershed and they determine many ecological characteristics of larger downstream channels.--Document.

Framework to Support Impact Analyses of Renewal Strategies of Forestlands Affected by Mountain Pine Beetle by Emina Krcmar,Ann Chan-McLeod,Livia Bizikova Pdf

We developed a decision-support framework that integrates scenario analysis and multi-criteria decision analysis and used it to analyze forest renewal in the study area of the Quesnel Timber Supply Area. Two consensus-based scenarios were constructed to represent the target future conditions: strong forest sector and forest resilience/economic diversification. Renewal strategies were constructed using multi-criteria decision analysis and sets of criteria specific to each scenario. Impacts of the renewal strategies are measured in terms of several timber and non-timber indicators. The key economic and timber-related impacts are linked to merchantable volume. Ecological impacts are assessed by analyzing wildlife communities associated with the broad habitat categories. None of the strategies generated for the scenarios was acceptable in terms of all criteria and outcomes. Further revisions of the scenarios and criteria, with the involvement of local stakeholders, is therefore recommended for decision-making. The integrated framework developed for this study is general and allows for other community and forest management concerns to be incorporated. The framework demonstrates how the stakeholders' goals regarding their community's future are formulated and how the conflicts between multiple criteria may be addressed.

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.

Public Perceptions of Mountain Pine Beetle Management Alternatives by Mike Meitner 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. The purpose of this paper was to build the capacity to visualize natural disturbances common in British Columbia with specific emphasis on creating the ability to represent possible forest futures related to the mountain pine beetle epidemic. A second objective was to utilize this new found technical ability to create scenario visualizations of possible management trajectories to be used in public perception research to investigate a number of research questions. Specifically, the report investigates the public acceptability of possible management alternatives.--Includes text from Government of Canada publications site and from document.

Decision Support Framework for Assessing Alternative Mountain Pine Beetle Management Strategies on Sustainable Forest Management by Ann Chan-McLeod,Pierre Vernier,Stephen Jarvis Mitchell Pdf

We developed a decision support framework that facilitates the assessment of alternative mountain pine beetle (MPB) management strategies on wildlife and other sustainable management indicators. Specifically, the framework permits the evaluation of ecological trade-offs (i.e., the probability of occurrence of bird species; landscape composition and configuration; wildlife habitat supply) under alternative salvage logging strategies. An additional function of the framework is to identify areas of uncertainty where data gaps continue to limit decision-making. We demonstrated the application of the decision support framework by evaluating the consequences of five specific salvage harvesting strategies in a case study of a forest landscape in northeastern British Columbia. The five strategies included: 1) a baseline scenario based on current management practices in MPB-affected landscapes; 2) a scenario for salvage-logging-only stands with high pine composition; 3) a scenario for salvage logging stands that included minimal pine; 4) a low retention scenario where relatively few trees are retained within large cutblocks; and 5) a high retention scenario where more trees are retained in large cutblocks than currently practiced. In our case study, we used a subset of the components identified in the conceptual framework since many parameters (e.g., stand-level attributes) were not widely available and could not be scaled up to the case study landscape. The components were for: 1) simulating infestation, salvage logging and forest succession, 2) tracking landscape-level changes in avian probability of occurrence and supply of broad habitat types, and 3) facilitating scenario analysis and decision-making. We identified some broad patterns in species responses over time and helped to identify areas of uncertainty that are the result of model limitations and data gaps. In our case study, avian response was dictated more by the bird species' natural history traits than by differences between management regimes. However, eligibility criterion for salvage logging (i.e., the amount of pine in the stand) was generally more important than the stand retention levels used in our simulations in governing post-harvesting avian response.

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.

Hydrologic Effects of Mountain Pine Beetle Infestation and Salvage-harvesting Operations by John F. Rex,Stéphane Dubé Pdf

This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.
