This book was released on 2008 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle (MPB) epidemic. The objective of this report was to determine watershed-scale impacts of mountain pine beetles by comparing channel conditions and the woody debris budget in watersheds infested by the MPB with those from similar old-growth forests with pre-infestation channel and riparian data. The use of a woody debris budget directly links large-scale lodgepole pine mortality to stream challen and piparian processes and conditions at the landscape level. Eighteen watersheds in the Sub-Boreal Spruce and Sub-Boreal--Pine Spruce biogeoclimatic zones were considered. The results are used to generate regionally and locally relevant best management practices that will guide operational planning in landscapes impacted by the MPB.--Includes text from Government of Canada publications site and from document.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Disturbance regimes are important determinants of both terrestrial and aquatic ecosystem structure and function. Disturbances may linger in the landscape and lag temporally, influencing stream ecosystem form and function for decades, if not centuries. The recent enhanced Mountain Pine Beetle (MPB) infestation in pine forests of the Rocky Mountain region has resulted in extensive tree mortality, producing the potential for significant increases in carbon supply to stream channels. To better understand MPB impacts on in-stream large wood (LW), a census was conducted in 30 headwater streams within the Medicine Bow National Forest in south-central Wyoming, across the temporal spectrum from early- to late-stage MPB-infestation. A subset of those streams exhibiting mean conditions at each level of infestation was surveyed to determine any significant differences in channel morphology or aquatic ecosystem function. Results indicate that wood loads related to the MPB-infestation significantly increase with time since initial infestation. However, even in late-stage infestation streams, many of the fallen MPB-killed trees are bridging across the channels and have yet to break and ramp down sufficiently enough to enter between the channel margins. Wood loads will continue to increase as more trees fall and bridging pieces decompose, break and then enter the channel. Measurable increases in the amount of LW with time since initial beetle infestation have both positive and negative effects on channel form and function. Although forest MPB-infestation has peaked in the study area, streams are still early on a curve of rapidly increasing wood loads that are beginning to affect streams and have the potential to dramatically increase the carbon base of regional stream ecosystems.

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 2008 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report outlines the objectives, study design, methods of data collection, and other details relevant to the establishment of Experimental Project (EP) 1369: A Framework for Documenting the Effects of the Mountain Pine Beetle in Sub-boreal Forests of Northern British Columbia. In 1995 through 1997, 48 plots were established in mature pine leading stands affected by mountain pine beetle (MPB) (38 plots) and MPB followed by wildfire (10 plots). All plots will remain unharvested, and are designed to examine ecological changes subsequent to these disturbances. The information from these plots will inform science on what ecological changes result from these disturbances in the sub-boreal forest landscape, and will provide critical information (such as growth rate of live understorey) to land managers."--Document.

Book excerpt: "The purpose of this study is to evaluate the condition of streams and riparian zones in a watershed after a substantial amount of time has passed since logging. The Bowron River watershed was chosen based on past harvesting challenges similar to those associated with the mountain pine beetle outbreak and a post-logging recovery time of 20-30 years. By evaluating a watershed in an advanced stage of recovery, it is possible to identify impacts to the riparian system and use the information to consider whether adverse effects will be manifested as a result of compounding forest activities and hydrological response under present forest management practices. The evaluation also provides insight into which components recover first."--Document.

This book was released on 2009 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports on the investigation of the influence of the mountain pine beetle infestation and salvage harvesting on small stream and riparian zone ecological function, shade, and temperature. Small streams (less than a 2 m bankfull width) were selected because they are the most prominent stream type within a watershed and they determine many ecological characteristics of larger downstream channels.--Document.

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.
