Mountain pine beetle attack alters the chemistry and flammability of lodgepole pine foliage
Year: 2012
During periods with epidemic mountain pine beetle (Dendroctonus ponderosae Hopkins) populations in lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests, large amounts of tree foliage are thought to undergo changes in moisture content and chemistry brought about by tree decline and death. However, many of the presumed changes have yet to be quantified. In this study, we quantified and compared fuel moisture, chemistry, and resulting flammability of bark beetle affected foliage in terms of ignitability, combustibility, consumability, and sustainability at a site in far…

Is Proactive Adaptation to Climate Change Necessary in Grazed Rangelands?
Year: 2012
In this article we test the notion that adaptation to climate change in grazed rangelands requires little more effort than current approaches to risk management because the inherent climate variability that characterizes rangelands provides a management environment that is preadapted to climate change. We also examine the alternative hypothesis that rangeland ecosystems and the people they support are highly vulnerable to climate change. Past climate is likely to become an increasingly poor predictor of the future, so there is a risk in relying on adaptation approaches developed solely in…

Climate Change, Forests, Fire, Water, and Fish: Building Resilient Landscapes, Streams, and Managers
Year: 2012
Fire will play an important role in shaping forest and stream ecosystems as the climate changes. Historic observations show increased dryness accompanying more widespread fire and forest die-off. These events punctuate gradual changes to ecosystems and sometimes generate stepwise changes in ecosystems. Climate vulnerability assessments need to account for fire in their calculus. The biophysical template of forest and stream ecosystems determines much of their response to fire. This report describes the framework of how fire and climate change work together to affect forest and fish…

Pole Creek Fire
Year: 2012
In September 9, 2012 a lightning strike hit the Pole Creek trailhead in the Deschutes National Forest, approximately 8 miles southwest of Sisters, Oregon. The wildfire was contained on October 17th after spreading over 26,000 acres of timber and brush. In response to this event, the Northwest Fire Science Consortium partnered with Oregon State University (OSU) College of Forestry, OSU Forestry & Natural Resources Extension, USFS Region 6, and the Central Oregon Fire Management Service to offer an opportunity for in-the-field learning in the immediate post-fire environment. Targeted…
