Download or read book Growth of Ponderosa Pine Stands in Relation to Mountain Pine Beetle Susceptibility written by and published by . This book was released on 1999 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten-year diameter and basal area growth were determined for partially cut stands at 4 locations. Average diameters in the partially cut plots generally increased by 1 inch or more, while average diameter in the uncut controls increased by 0.9 inches or less. Individual tree growth is discussed in relation to potential susceptibility to mountain pine beetle infestation. Basal area increases ranged from 0.9 to 1.9 ft2/acre/ yr in partially cut plots, while basal area increases in the control plots ranged from 0.4 to 1.4 ft2/acre/yr. Endemic mountain pine beetle infestations and snow breakage accounted for most of the mortality on the plots, which decreased the residual basal area and basal area growth. Increases in basal area are used to estimate the length of time required for various stand densities to reach the susceptibility thresholds for mountain pine beetle infestation. Stand marking may influence future susceptibility to beetle infestations.

Download or read book The Mountain Pine Beetle written by Pacific Forestry Centre and published by . This book was released on 2006 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Mountain Pine Beetle Attack in Ponderosa Pine Comparing Methods for Rating Susceptibility written by David C. Chojnacky and published by . This book was released on 2000 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two empirical methods for rating susceptibility of mountain pine beetle attack in ponderosa pine were evaluated. The methods were compared to stand data modeled to objectively rate each sampled stand for susceptibly to bark-beetle attack. Data on bark-beetle attacks, from a survey of 45 sites throughout the Colorado Plateau, were modeled using logistic regression to estimate the probability of attack on individual trees from tree and stand variables. The logistic model allowed flexibility to easily scale results up to a stand level for comparison to the empirical methods. The empirical method, developed by Munson and Anhold, most closely correlated to the logistic regression results. However, the Munson/Anhold method rated all 45 study sites as either moderately or highly susceptible to bark-beetle attack, which raises concern about its lack of sensitivity. Future work on evaluating risk of bark-beetle impact should consider more than stand characteristics.

This book was released on 2018 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clifford A. Myers conceived the ponderosa pine growing stock levels (GSL) study in 1961 and completed installation of the study in 1963 in western South Dakota on the Black Hills Experimental Forest (BHEF). The GSL concept was intended to help plan, implement, and illustrate tree thinning strategies (from below) in even-aged stands. A GSL is the suggested tree density (i.e., trees and basal area per acre) based on d.b.h. that can be tended to produce a desired basal area per acre (e.g., 80, 100, 120 square feet) when the mean d.b.h. is 10 inches. Plots representing GSLs 20, 40, 60, 80, 100, and 120 were thinned and measured through 2014. The thinnings that occurred in the GSL 80 plots showed the most promise for producing commercially sized trees and volumes through 2010. Unfortunately, by 2014, mountain pine beetles killed trees in all of the plots and ended the study.
