Fire, Fuel and Smoke


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.
Tree-rings are used to reconstruct fire and forest histories in central Oregon.
Experiments to Improve Agricultural Smoke Decision Support Tools
Researchers measured surface fuel litterfall and decomposition in the northern Rocky Mountains, United States. These rates were used to estimate fuel dynamics parameters in complex landscape models of fire and vegetation dynamics.
