Microclimate and Mountain Pine Beetles in Two Ponderosa Pine Stands in the Black Hills (Classic Reprint) by J. M. Schmid Pdf
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.

Mountain Pine Beetle Attack in Ponderosa Pine: Comparing Methods for Rating Susceptibility by David C. Chojnacky Pdf
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.

Mountain Pine Beetle-killed Trees as Snags in Black Hills Ponderosa Pine Stands by J. M. Schmid Pdf
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.

Growth of Ponderosa Pine Stands in Relation to Mountain Pine Beetle Susceptibility by Anonim Pdf
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.
