Book Description
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 Description
This work advises owners and managers how woodlands and forests influence the freshwater ecosystem, and gives guidance on how operations should be carried out in order to protect and enhance the water environment. The guidelines apply equally to forest enterprises and the private sector.

The objectives of this study were to: 1. compare the key environmental variables between blocks (elevational effect) and treatments (clearcut and irregular group shelterwood with whole-tree harvesting partial cut), and between microsites within partial cut openings (north and south edges and centre); and 2. examine temporal changes occurring to environmental variables in the context of the changing biological environment. This document includes an introduction, methods, results and discussion, and a summary.--Includes text from document.

Book Description
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.

Book Description
"This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

Book Description
Water does not come from the river. It comes to the river. Heart Waters takes us to the sources of that water - and into the living beauty, human stories and future possibilities that also arise from the green slopes and valleys of Alberta's Eastern Slopes where the Bow River is born. For more than a century ago the foothills and Front Range mountains of western Alberta have been recognized vital to the future water supply for Canada's prairies. Virtually all the water that sustains communities, ecosystems and the economy of prairie Canada comes from this narrow strip of land arrayed along the Continental Divide. For all its importance, however, water management decisions have ignored the importance of land health and focused almost exclusively on building dams. The result, as the author points out, is that the Bow River's annual flows have decreased by more than a tenth, even while spring floods become more frequent and more destructive. The solutions to prairie Canada's water challenges lie in healing the wounded landscapes of our headwaters. Heart Waters delves deeply into the history and ecology of a landscape whose critical value as a watershed is matched by its sheer beauty and diversity. A rich array of stunning photographic imagery by Jasper-based photographer Brian Van Tighem complements the author's well-researched explorations of the stories whispered by the living waters that drain from Banff National Park, Kananaskis Country and the famous ranchlands of the Bow River watershed. Heart Waters is a deep exploration of place, and an invitation to recognize that our water future depends upon knowing our headwaters better and caring for them more passionately - as our heart waters. "We could belong here too," the book concludes. "We could be like the bull trout, the willows, the wary horses: like the river that continually arises from these fine green places where the waters are born. We could find our best selves in the stories of those living waters and the river that gathers them together."
