Influence of winter season climate variability on snow-precipitation ratio in the western United States

Publications Posted on: April 20, 2016
In the western United States, climate warming poses a unique threat to water and snow hydrology because much of the snowpack accumulates at temperatures near 0 °C. As the climate continues to warm, much of the region's precipitation is expected to switch from snow to rain, causing flashier hydrographs, earlier inflow to reservoirs, and reduced spring and summer snowpack.

Opportunities to utilize traditional phenological knowledge to support adaptive management of social-ecological systems vulnerable to changes in climate and fire regimes

Publications Posted on: March 03, 2016
The field of adaptive management has been embraced by researchers and managers in the United States as an approach to improve natural resource stewardship in the face of uncertainty and complex environmental problems. Integrating multiple knowledge sources and feedback mechanisms is an important step in this approach.

Climate change effects on wildlife habitat in the Rocky Mountain Region

Projects Posted on: September 17, 2015
Climate change will affect wildlife directly through temperature and moisture changes and indirectly through habitat availability as vegetation types and ecosystem productivity changes. Our study focuses on the western United States, on an annual time frame, and at a 0.083 degree grid cell spatial scale.

Combined effects of a changing climate drive mountain pine beetle outbreaks

Science Spotlights Posted on: September 09, 2015
An ideal combination of temperature and precipitation associated with a changing climate are responsible for recent Mountain Pine Beetle population outbreaks. Field-validated models that describe the intricate temperature-dependent processes that foster Mountain Pine Beetle success allows us to predict forest vulnerability in a changing climate.

The use of shaded fuelbreaks in landscape fire management

Publications Posted on: August 03, 2010
Shaded fuelbreaks and larger landscape fuel treatments, such as prescribed fire, are receiving renewed interest as forest protection strategies in the western United States. The effectiveness of fuelbreaks remains a subject of debate because of differing fuelbreak objectives, prescriptions for creation and maintenance, and their placement in landscapes with differing fire regimes.

Publications Posted on: September 25, 2009
Astragalus filipes Torr. ex A. Gray (basalt milkvetch or threadstalk milkvetch) is a legume that is widely distributed in western North America andholds promise for revegetation and restoration programs in the western United States. Seed of 67 accessions was collected in 2003 from Utah, Nevada, Idaho, Oregon, California, and Washington.

Book review: Understanding human development in the western United States

Publications Posted on: May 04, 2009
Isn't that development new?" is perhaps the phrase most frequently uttered by people who live in the western US. The West, it seems, is sucking Americans into its precious places at a rate that is unparalleled in recent US history. As humans continue to diffuse into the western landscape, they bring their corresponding demands for energy, transportation, water, amenities, and recreation.

Gambel oak (Quercus gambelii Nutt.) covers 3.75 million hectares (9.3 million acres) of the western United States. This report synthesizes current knowledge on the composition, structure, and habitat relationships of gambel oak avian communities. It lists life history attributes of 183 bird species documented from gambel oak habitats of the western United States.

Wilderness and backcountry site restoration guide

Publications Posted on: April 02, 2007
This comprehensive guide focuses on restoration of small-scale impact caused by human actions in wilderness and backcountry areas. The guide's goals are to: 1) Help practitioners develop plans that thoroughly address the question of whether site restoration is the best management action and, if so, develop a site-specific restoration plan that incorporates ecological concepts and addresses patterns of human use.
