Precipitation declines in Pacific Northwest mountains

Documents and Media Posted on: January 23, 2015
A rapidly warming climate across the Pacific Northwest is altering the volume, timing, and quality of water received from winter snowpack. Historic observations show increased dryness accompanying more widespread wildfire and forest die-off. These trends have generally been attributed to warming temperatures because measurement gauges at lower elevations throughout the region showed no significant decrease in precipitation.Document Type: Briefing Papers

NorWeST: a regional stream temperature database and modeled climate scenarios

Documents and Media Posted on: January 23, 2015
Climate change is warming aquatic ecosystems and will have profound consequences. Effective conservation of aquatic resources will require unprecedented levels of interagency coordination.  In addition, it will require the development of datasets and models for accurate downscaling of climate change effects to important habitat parameters and species distributions at local scales.Document Type: Briefing Papers

Western spruce budworm alters crown fire behavior through reduced canopy density

Projects Posted on: January 22, 2015
In the interior West, western spruce budworm outbreaks often last for decades, but their impact on fire behavior is poorly understood. By isolating the effects of the insect on a single tree and simulating the tree in a three-dimensional fire model, researchers were able to identify precise links between western spruce budworm disturbance and fire behavior changes.

Effects of "daylighting", a new restoration technique, on whitebark pine stands in the Northern Rocky Mountains

Projects Posted on: January 22, 2015
Whitebark pine trees, a valuable keystone species that provides food to hundreds of wildlife species, cover a significant portion of national forests in the Northern Rocky Mountains but have been rapidly declining because of blister rust infections, mountain pine beetle outbreaks, and fire exclusion. A restoration technique called daylighting, in which competing trees that surround the whitebark pine are removed, is playing an increasing role in whitebark pine restoration.

Central Oregon fire history: fire and forest histories of central Oregon from tree rings

Waste to wisdom: Using waste woody biomass to create biochar for soil restoration

Projects Posted on: December 03, 2014
The application of biochar to forest soils to improve soil productivity shows promise in many areas, although many soil impacts still need to be described. Numerous field and lab studies are ongoing in the inland Northwest that will help determine the most appropriate biochar sources and soil types for applying biochar.  

NorWeST Stream Temperature

Tools Posted on: August 05, 2014
NorWeST aggregates stream temperature data from the Northwestern U.S. into a stream temperature database, and uses the data to develop stream temperature models.
