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.

This book was released on 2009 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain pine beetle-killed ponderosa pine trees in three stands of different stocking levels near Bear Mountain in the Black Hills National Forest were surveyed over a 5-year period to determine how long they persisted as unbroken snags. Rate of breakage varied during the first 5 years after MPB infestation: only one tree broke during the first 2 years in the three stands; breakage increased during the third year; the highest percentage of snags broke during the fourth year; and 10% to 14% broke in the fifth year. Cumulatively, snag breakage was 76%, 91%, and 95% in a GSL 80/90, GSL 100/110, and unmanaged stand, respectively. On average, 56% of the snags broke below 25 ft. The rate and height of breakage in mountain pine beetle-killed trees indicates that they are unlikely to persist as suitable snags for more than 5 to 10 years after infestation.

Book excerpt: The S2Mountain Pine Beetle Symposium: Challenges and SolutionsS3 was held in Kelowna, British Columbia, Canada on October 30-31, 2003. This meeting was organized by Natural Resources Canada, Canadian Forest Service, Pacific Forestry Centre and funded through the Government of Canada Mountain Pine Beetle Initiative. Approximately 250 people representing the forest industry, consultants, universities, provincial and federal government agencies, First Nations, and the general public, from both Canada and the United States attended the meeting. Thirty presentations were given describing the current mountain pine beetle situation (in British Columbia, Alberta and the western United States) and its management and economic implications. Researchers presented the latest information on remote sensing, decision support systems, impacts on stand dynamics and wildlife, phytosanitary risks, climate change effects and preventive management as they relate to mountain pine beetle.

This book was released on 2019-01-24 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Microclimate and Mountain Pine Beetles in Two Ponderosa Pine Stands in the Black Hills Infestations of mountain pine beetles (dendroctonus ponderosae Hopkins) may be common in unthinned pine stands but are uncommon in thinned stands. Subtle differences in the biotic and abiotic stand conditions may account for the numbers of beetle attacked trees in the two types of stands. The abiotic conditions, generally referred to as microclimate, are thought to play an important role. Epidemics of the mountain pine beetle (mpb) commonly develop in relatively unmanaged stands of pure ponderosa pine (pinus ponderosa Lawson) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Considering the Effectiveness of Mountain Pine Beetle Mitigation Strategies written by Nicholas C. Coops and published by . This book was released on 2008 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the broad range of mitigation strategies associated with the management of mountain pine beetle (Dendroctonus ponderosae Hopkins), including methods that are currently utilized or proposed for controlling beetle populations, the manner in which the effectiveness of these approaches is monitored and assessed and, finally, the role that remotely sensed data may play in a large-area monitoring system. To this end, the authors first review the goals of effectiveness monitoring and introduce a general classification system to clarify the purpose and practice of efficacy monitoring. Based on these principles, the review is then structured around effectiveness evaluations for managing forest pests, primarily mountain, southern, and western pine beetles throughout North America. These evaluations are grouped by management strategy: silvicultural treatments; prescribed burns; and the use of attractants, repellants, and insecticides. Finally, the authors propose the use of remotely sensed data as a complementary tool for monitoring changes in the extent and severity of mountain pine beetle damage across large areas.--Document.
