Mountain Pine Beetle Impacts on Channel Morphology and Woody Debris in Forested Landscapes by Marwan Hassan Pdf

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.

Mountain Pine Beetle by Fred L. Bunnell,L. L. Kremsater,Isabelle Houde Pdf

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.

The Bowron River Watershed by Anonim Pdf

"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.

A Framework for Documenting the Effects of the Mountain Pine Beetle Outbreak in Sub-boreal Forests of Northern British Columbia (E.P. 1369) by Ben Heemskerk,C. DeLong,Tanya Milner Pdf

"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.

Mountain Pine Beetle and Salvage Harvesting Influence on Small Stream Riparian Zones by John F. Rex Pdf

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.

Historic Influence of the Mountain Pine Beetle on Stand Dynamics in Canada's Rocky Mountain Parks by Pamela Dykstra,T. F. Braumandl,Hawkes, B. C. (Brad C.),Pacific Forestry Centre Pdf

The Canadian government announced the Mountain Pine Beetle Initiative (MPBI) in 2002 to address the socio-economic and ecological consequences of an epidemic of mountain pine beetle (Dendroctonus ponderosae Hopkins). The objective of this study was to establish baseline information on the ecological characteristics that occur at different stages of succession, resulting from mountain pine beetle disturbance at different time intervals. Key issues addressed by this study were: the post-beetle ecological character of stands; the ecological legacies that should be sought post-beetle; maintenance of ecological integrity in beetle-damaged landscapes; and the impacts of beetles on regeneration. This paper presents a study of stand conditions following two historic mountain pine beetle outbreaks events in the 1940s and 1980s. The study quantified structural and species composition of stands at different stages of succession (25 years and 65 years), and quantified the differences that occur in forest development between stands with and without disturbance by the beetle. It concludes with several recommendations for management of post-disturbance landscapes.

Modeling Large Woody Debris Recruitment for Small Streams of the Central Rocky Mountains by Don C. Bragg Pdf

As our understanding of the importance of large woody debris (LWD) evolves, planning for its production in riparian forest management is becoming more widely recognized. This report details the development of a model (CWD, version 1.4) that predicts LWD inputs, including descriptions of the field sampling used to parameterize parts of the model, the theoretical and practical underpinnings of the model's structure, and a case study of CWD's application to a stream in Wyoming's Bridger-Teton National Forest.

Environmental Effects on Host Selection and Dispersal of Mountain Pine Beetle by Mary Lynn Reid Pdf

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 epidemic. It summarizes the results of a study on the landscape variation in lodgepole pine constitutive defences, primarily measured as resin production, but also as phloem monoterpene concentration. The response of pioneer mountain pine beetles to those defences is reviewed, measured by experimentally placing beetles on trees and by attacks of free-flying beetles; effects of beetle quality (size, condition) on the beetles' responses are also examined. Finally, the results on the dispersal of mountain pine beetles through a mature lodgepole pine stand and a burned stand are presented.--Includes text from Government of Canada publications site and from document.

Evaluation of Risk Assessment of Mountain Pine Beetle Infestations by Caren C. Dymond Pdf

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 epidemic. In this paper, an established decision support system was evaluated for operational use. Digital forest inventory and beetle-impact survey data were integrated in standard GIS software for rating susceptibility and risk of mountain pine beetle infestation. The beetle-impact data, collected over a three-year period, provided an opportunity to generate risk on a given year and compare it to attacks in the subsequent year.--Includes text from Government of Canada publications site and from document.
