This book was released on 2016 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain pine beetle (Dendroctonus ponderosae) infestation has affected large areas of the central and southern Black Hills of western South Dakota, similar to elsewhere in the Rocky Mountains. The hydrologic response of watersheds to pine beetle infestation has been studied by other researchers; these were typically for sub alpine settings where runoff is dominantly derived from snowpack. There is a need for investigations of the hydrologic response of ponderosa pine (Pinus ponderosa) forests, which are not snow dominated systems, but rather are semi-arid settings where evapotranspiration potentially plays a greater role in the hydrologic budget. The Rainfall Response Aquifer and Watershed Flow (RRAWFLOW) model has been successfully used to model springflow in the Black Hills, including Rhoads Fork Spring in the headwaters of Rapid Creek.

This book was released on 2018 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Black Hills National Forest (BHNF) spans seven counties in western South Dakota and eastern Wyoming and is estimated to contain more than 470,000 hectares of forested land. The dominance of a single tree species, Pinus ponderosa, makes the BHNF especially susceptible to forest pests like the mountain pine beetle (MPB; Dendroctonus ponderosae). The goal of this study was to investigate the hydraulic impacts on surface water due to MPB infestation. A total of 26 sample locations within 9 watersheds were sampled from May 2017 to October 2017, with sample locations representing areas both heavily impacted by the MPB and areas unimpacted. Water quality analysis was performed on these samples using analytical techniques including combustion analysis, ion chromatography, titration, electronic probes, fluorescence spectroscopy, and turbidity analysis.

Download or read book A Synthesis of the Hydrological Consequences of Large scale Mountain Pine Beetle Disturbance written by Markus Schnorbus and published by . This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current synthesis is a review of research examining the effects of large-scale mountain pine beetle (MPB)-related disturbance conducted predominantly over the past five years. The emphasis is on research that explicitly examines the impact of beetle kill (or biotic disturbance in general) and the cumulative effects of large scale salvage harvesting operations in response to beetle kill. In general, forest disturbance has been found to increase snow accumulation and melt, reduce interception loss and evaporation, and increase runoff and stream flow.--Document.

This book was released on 2009 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.

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 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.
