Projected Future Changes in Vegetation in Western North America in the Twenty-First Century
Year: 2013
Rapid and broad-scale forest mortality associated with recent droughts, rising temperature, and insect outbreaks has been observed over western North America (NA). Climate models project additional future warming and increasing drought and water stress for this region. To assess future potential changes in vegetation distributions in western NA, the Community Earth System Model (CESM) coupled with its Dynamic Global Vegetation Model (DGVM) was used under the future A2 emissions scenario. To better span uncertainties in future climate, eight sea surface temperature (SST) projections provided…

Restoring & Managing Mixed Conifer Forests in the PNW
Year: 2013
Many collaborative groups working across the eastside of Oregon and Washington have developed good working agreements on treatments appropriate for ponderosa pine forest types. These groups are actively supporting and helping to develop projects that will meet ecological objectives for dry forests while generating jobs and economic activity in local communities. Currently, there is less agreement on how to approach restoration and management of mixed-conifer forests, in large part because there does not appear to be a comparable scientific consensus as that which exists for ponderosa pine…

Management of Cheatgrass Fuel Loading in the Shrub-Steppe
Year: 2013
The Columbia Basin Natural Wildlife Refuge (CNWR) had been periodically grazed until the Refuge was established in 1944. Cheatgrass became a prominent plant in the area. In 1986 a fire occurred near the study area. The area was reseeded with Elymus wawawaiensis (Snake River Wheatgrass, Secar cultivar). This grass has established reducing cheatgrass cover to very low levels. The study area was established in 2002 to test hypotheses on the effects of herbicides on plant community structure and establishment of Elymus wawawaiensis. In 2002 study plots were established and characterized before…

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…

Assessing tree health
Year: 2011
Healthy trees are beneficial to our environment and our property values - but how do we determine if a tree is healthy? This publication briefly discusses common tree health problems and outlines a procedure for assessing tree conditions and getting diagnoses and recommendations from tree health professionals.

Reducing Fire Risk on Your Forest Property
Year: 2010
Whether you own a few acres or thousands, this publication will help you reduce the potential for wildfire damage on your property while improving overall forest health and wildlife habitat. Although these actions won’t prevent a wildfire from coming onto your property, they can make it more fire resistant. In other words, by following the guidelines in this publication you can reduce a fire’s severity so that most trees survive and firefighters are better able to attack and extinguish the blaze. While this publication provides suggestions for making your property more fire-resistant, it does…

A Tale of Two Cedars: International Symposium on Western Redcedar and Yellow-Cedar
Year: 2010
From May 24-28, 2010, an international symposium on western redcedar (Thuja plicata) and yellow-cedar (Callitropsis nootkatensis [syn. Chamaecyparis nootkatensis]) was held at the University of Victoria on Vancouver Island in British Columbia, Canada. The symposium was entitled “A Tale of Two Cedars” and brought together local, regional, national, and international experts to present cultural, biological, management and economic information on the two species. Although some papers or posters focused on just one of the cedars, many of the presenters covered both species and discussed the…
