Download or read book Hydrologic Effects of Mountain Pine Beetle Infestation and Salvage-harvesting Operations written by John F. Rex and published by . 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.

Book Synopsis Quantifying the Water Resource Impacts of Mountain Pine Beetle and Associated Salvage Harvest Operations Across a Range of Watershed Scales by : Markus Schnorbus
Download or read book Quantifying the Water Resource Impacts of Mountain Pine Beetle and Associated Salvage Harvest Operations Across a Range of Watershed Scales written by Markus Schnorbus and published by Canadian Museum of Civilization/Musee Canadien Des Civilisations. This book was released on 2010 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the results of a project done to assess the potential for impacts and changes to the peak-flow regime throughout various sub-basins of the Fraser River Watershed. The vast size and the physical complexity of the Fraser River Basin make it extremely difficult to directly measure the hydrologic effects of beetle kill and salvage harvesting. As a result, a hydrology model has been used to assess the hydrologic consequences of the current outbreak. The project is part of a larger effort in quantifying the water resource impacts of the pine beetle and salvage harvesting across a range of watershed scales.--Includes text from document.
Book Synopsis A Synthesis of the Hydrological Consequences of Large-scale Mountain Pine Beetle Disturbance by : Markus Schnorbus
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.
Book Synopsis Forest Hydrology and Watershed by : Fan-Rui Meng
Download or read book Forest Hydrology and Watershed written by Fan-Rui Meng and published by MDPI. This book was released on 2019-08-20 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrological processes in forested watersheds are influenced by environmental, physiological, and biometric factors such as precipitation, radiation, temperature, species type, leaf area, and extent and structure of forest ecosystems. Over the past two centuries, forest coverage and forest structures have been impacted globally by anthropogenic activities, for example, forest harvesting, and conversion of forested landscapes for plantations and urbanization. In addition, since the industrial revolution, climate change has resulted in profound impacts on forest ecosystems due to higher carbon dioxide (CO2) concentration or CO2 fertilization, warmer temperatures, changes in frequency and intensity of extreme weather events and natural disturbances. As a result, hydrological processes in forested watersheds have been altered by these natural and anthropogenic factors and these changes are expected to accelerate due to future changing climatic conditions. Hence, understanding how various environmental, physiological, and physical drivers interactively influence hydrological and biogeochemical processes in forest ecosystems is critical for sustainable water supply in forested watersheds. About 21% of the global population depends on water sources that originate in forested catchments where forest coverage larger than 30%. Furthermore, there are knowledge gaps in our understanding of the mechanism of hydrological and hydrochemical cycles in forested watersheds. This Special Issue addresses these gaps in our knowledge and includes twelve papers in the following three major research themes in forest watershed areas.

Book Synopsis Mountain Pine Beetle by : Fred L. Bunnell
Download or read book Mountain Pine Beetle written by Fred L. Bunnell and published by . This book was released on 2011 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a synthesis of recently completed studies to assess the ecological consequences of forest management after attack by mountain pine beetle or other large-scale disturbances. Studies are assessed for their contributions to gaps in knowledge previously identified in the Mountain Pine Beetle Initiative Working Paper "Evaluating effects of large scale salvage logging for mountain pine beetle on terrestrial and aquatic vertebrates," which was published in 2004. This report focuses on studies developed through the federal Mountain Pine Beetle Initiative, the federal Mountain Pine Beetle Program, and the complementary BC Forest Science Program. Relevant information from other jurisdictions is sometimes included to augment those studies. Topics examined are: the impacts of beetle kill and salvage operations on habitat attributes; the impacts of beetle kill and salvage operations on attendant processes, such as snag fall rates, light interception, and snow accumulation; and the wildlife response to large-scale beetle outbreaks and management strategies. For each of these three topics, we provide a summary of: research to date; pertinent findings to date; and gaps in research.

This book was released on 2005 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report highlights past delivery of the land-based programs and progress of mountain pine beetle research during 2003 & 2004 by the Mountain Pine Beetle Initiative, a six-year program established to address the mountain pine beetle epidemic in western Canada and to reduce the risk of future such epidemics. After an introduction on the epidemic and the Initiative, the report summarizes the accomplishments of the Private Forestlands Rehabilitation Program, the Federal Forestlands Rehabilitation Program (First Nations, National Parks, and Other Federal Forestlands components), and the research & development program (including research on ecology, forest economics, socio-economic processes & risk reduction). Finally, the next steps in the land-based and research & development programs are discussed.
Book Synopsis Compendium of Forest Hydrology and Geomorphology in British Columbia by : Robin G. Pike
Download or read book Compendium of Forest Hydrology and Geomorphology in British Columbia written by Robin G. Pike and published by University of British Columbia Press. This book was released on 2010 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, hydrologists and geomorphologists have often discussed the need to document the history, scientific discoveries, and field expertise gained in watershed management in British Columbia. Several years ago, a group of watershed scientists from FORREX, academia, government, and the private sector gathered at the University of British Columbia to discuss the idea of a provincially relevant summary of hydrology, geomorphology, and watershed management. Through this meeting, the Compendium of Forest Hydrology and Geomorphology was born. As a synthesis document, the Compendium consolidates current scientific knowledge and operational experience into 19 chapters. To ensure reliable, relevant, and scientifically sound information, all chapters were extensively peer reviewed employing the standard double-blind protocol common to most scholarly journals. Chapters in the Compendium summarize the basic scientific information necessary to manage water resources in forested environments, explaining watershed processes and the effects of disturbances across different regions of the province. In short, the Compendium is about British Columbia and is primarily intended for a British Columbian audience, giving it a uniquely regional focus compared to other hydrology texts. At over 800 pages, the Compendium showcases the rich history of forest hydrology, geomorphology, and aquatic ecology research and practice in British Columbia and sets forth the foundation for the future by showing us how much more we have yet to learn.

Book Synopsis Effects of Overstorey Mortality on Snow Accumulation and Ablation by : Patrick Anthony Teti
Download or read book Effects of Overstorey Mortality on Snow Accumulation and Ablation written by Patrick Anthony Teti and published by . This book was released on 2009 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project documents stand structure and snow hydrology in both healthy and beetle-attacked pine stands of different ages over a large geographic area. Hydrologic changes are therefore expected in watersheds dominated by lodgepole pine due to the current mountain pine beetle epidemic and to salvage harvesting operations. The project assists in the development of process-based hydrologic models by providing stand-level data on the structure and snow hydrology of growing and deteriorating pine stands at different post-disturbance ages. This will help watershed modellers improve the accuracy of hydrologic predictions under different forest disturbance scenarios.--Includes text from document.

Book Synopsis Development and Application of a Peak-flow Hazard Model for the Fraser Basin (British Columbia) by : Martin Carver
Download or read book Development and Application of a Peak-flow Hazard Model for the Fraser Basin (British Columbia) written by Martin Carver and published by . This book was released on 2009 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The epicentre of the mountain pine beetle (MPB) outbreak at this time is in the Fraser River drainage basin in British Columbia. Due to the infestation's area and associated salvage harvest options, the potential exists for widespread and significant local and regional hydrologic impacts within the basin. The main objective of this paper is to estimate impacts from land-cover change on average peak flows for all third-order (1:50,000) watersheds in British Columbia because peak flows are a major concern for flood hazard, erosion and sedimentation impacts, and other hydrologic consequences. The goal is to provide a model that can be applied to all watersheds and, in particular, ungauged basins throughout the province.--Includes text from document and publisher's website.
Book Synopsis Development of a Low-flow Hazard Model for the Fraser Basin, British Columbia by : Martin Carver
Download or read book Development of a Low-flow Hazard Model for the Fraser Basin, British Columbia written by Martin Carver and published by . This book was released on 2009 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The epicentre of the mountain pine beetle (MPB) outbreak at this time is in the Fraser River drainage basin in British Columbia. Due to the infestation's area and associated salvage harvest options, the potential exists for widespread and significant local and regional hydrologic impacts within the basin. This paper discusses a low-flow hazard model that was developed for third-order catchments within the Fraser River watershed. Baseline and mountain pine beetle-infestation and harvest scenarios were modeled for seven catchments for direct comparison with the Variable Infiltration Capacity modeling results. The model is to be used in risk-based hydrology modeling to produce a comprehensive knowledge of mountain pine beetle-infestation effects on the hydrology of the Fraser River watershed and its major sub-basins in British Columbia, Canada.--Document.
Book Synopsis The Economics of Salvage Harvesting and Reforestation in British Columbia's Mountain Pine Beetle-affected Forests by : Brian Peter
Download or read book The Economics of Salvage Harvesting and Reforestation in British Columbia's Mountain Pine Beetle-affected Forests written by Brian Peter and published by . This book was released on 2010 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In stands with significant mountain pine beetle (MPB) mortality, forest managers face a range of choices including clearcut harvesting, partial cutting, various rehabilitation strategies, and non-intervention. These choices involve many long-term costs, benefits, and risks, some of which can be assessed through economic analysis. After reviewing the context for this issue, the authors provided case studies that span the more likely stand-level problems faced by decision makers. All analyses were conducted from the perspective of the landowner (i.e., government) rather than the user of the resource (i.e., licensee). The insights from the case studies form a basis to answer the following core questions: Are some stand types better left unsalvaged? What economic/silvicultural assumptions produce higher stand values when salvaging is foregone? In areas that cannot be salvaged, is reforestation a profitable investment? Finally, does partial cutting make sense economically?--Document.
