Forest Service science bolsters sagebrush and sage-grouse conservation

Media Gallery Posted on: September 16, 2016
Sagebrush ecosystems are among the largest and most threatened ecosystems in North America. Greater sage-grouse has served as the bellwether for species conservation in these ecosystems and has been considered for listing under the Endangered Species Act several times. The 2016 Conservation and restoration of sagebrush ecosystems and sage-grouse: An assessment of USDA Forest Service Science assessment will help meet continuing widespread concerns and calls for science-based conservation to mitigate threats to sagebrush ecosystems, conserve populations of sage-grouse and other sagebrush-obligate species, and restore sagebrush ecosystems throughout the western United States. 

Forage composition, productivity, and utilization in the Eastern Washington Cascade Range

Publications Posted on: August 20, 2016
Provision of forage for wild and domestic ungulates, and the associated impacts of their herbivory, are contentious issues for wildland management in western North America. We quantified the composition, above-ground net production (ANP), and utilization of herbaceous and shrub vegetation in five non-forest and seven forest cover types across the core spring-summer- fall range of the Yakima elk herd in the eastern Washington Cascade Range.

Forest Service science bolsters sagebrush and sage-grouse conservation

Science Spotlights Posted on: August 19, 2016
USDA Forest Service (FS) has been a leader for several decades in developing science and applications to support conservation and restoration of sagebrush ecosystems and sage-grouse populations. This spotlight describes an assessment that explains how and why understanding and supporting FS science is crucial for future management of sagebrush ecosystems.

Power lines restrict sage grouse movement in Washington

FS News Posted on: August 24, 2015
Transmission lines that funnel power from hydroelectric dams and wind turbines across Eastern Washington affect greater sage grouse habitat by isolating fragile populations and limiting movement, a new study finds.

Sage grouse population connectivity and landscape change

Science Spotlights Posted on: July 30, 2015
Recent connectivity assessments for the greater sage-grouse (Centrocercus urophasianus) in the Columbia Basin, Washington, provide an opportunity to (1) evaluate approaches for parameterizing resistance models based on sage grouse specifically or the concept of landscape integrity, (2) derive parameters from expert or empirical data, and (3) explore the influence of scale on model accuracy. Sage grouse in this region occupy a small fraction of their former range and are now threatened by extinction.

Synthesis of wind energy development and potential impacts on wildlife in the Pacific Northwest, Oregon and Washington

Publications Posted on: July 19, 2012
Nationally, there is growing public interest in and policy pressure for developing alternative and renewable sources of energy. Wind energy facilities in the Pacific Northwest expanded rapidly over the past decade, as a result of state policies that encourage wind energy development. While much of the development thus far has occurred on private lands, there is interest in expanding onto federal land.

Short-term responses of red squirrels to prescribed burning in the interior Pacific Northwest, USA

Publications Posted on: February 04, 2010
We quantified changes in density of red squirrels (Tamiasciurus hudsonicus) in response to prescribed fire in mixed coniferous forests of Idaho and Washington, USA, using a Before-After-Control-Impact design. We found no evidence that low-severity prescribed fires affected density of red squirrels; we estimated the change in red squirrel densities due to prescribed fire as 20.15 squirrels/ha (95% CI 5 20.4050.105).

Climate drivers of regionally synchronous fires in the inland northwest (1651-1900)

Publications Posted on: March 14, 2008
We inferred climate drivers of regionally synchronous surface fires from 1651 to 1900 at 15 sites with existing annually accurate fire-scar chronologies from forests dominated by ponderosa pine or Douglas-fir in the inland Northwest (interior Oregon,Washington and southern British Columbia).Years with widespread fires (35 years with fire at 7 to 11 sites) had warm spring - summers and warm-dry summers, whereas years with no fires at any site (

This chapter concentrates on subalpine parklands and alpine meadows of southern British Columbia, Washington, Oregon, and western Montana. These areas lie on the flanks of several mountain ranges including the Olympics, the Cascades of Oregon and Washington, and the Coast Mountains in British Columbia.
