Download or read book Natural Regeneration in Partial Cuts and Mature Forests After Mountain Pine Beetle Infestation in the West Chilcotin written by Nola Marie Daintith and published by . This book was released on 2015 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Framework to Support Impact Analyses of Renewal Strategies of Forestlands Affected by Mountain Pine Beetle written by Emina Krcmar and published by . This book was released on 2009 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Modeling Natural Regeneration Following Mountain Pine Beetle Attacks in the Southern and Central Interior of British Columbia written by Valerie M. LeMay and published by . This book was released on 2007 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Temporal Composition and Structure of Post beetle Lodgepole Pine Stands written by K. Runzer and published by . This book was released on 2008 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

This book was released on 2011 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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
