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.

The objectives of this study were to: 1. compare the key environmental variables between blocks (elevational effect) and treatments (clearcut and irregular group shelterwood with whole-tree harvesting partial cut), and between microsites within partial cut openings (north and south edges and centre); and 2. examine temporal changes occurring to environmental variables in the context of the changing biological environment. This document includes an introduction, methods, results and discussion, and a summary.--Includes text from document.

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.

"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.

In this paper the authors characterize lodgepole pine regeneration and the related micro-site conditions across a range of disturbance scenarios associated with mountain pine beetle (MPB) infestation and wildfire; indentify limitations for the germination, servival, recruitment and growth of natural and artificial regeneration in relation to the effects of site moisture, fire severity, and competition by vegetation; and provide guidance on how to manage beetle-infested lodgepole pine stands subsequently burned by wildfires. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.

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.
