Fire Returns To Southern Appalachian Forests, Elise Lequire Jan 2009

Fire Returns To Southern Appalachian Forests, Elise Lequire

Joint Fire Science Program Briefs (2007-2012)

In the Daniel Boone National Forest (DBNF) in eastern Kentucky, controlled experiments are shedding light on the role of fi re in meeting an urgent need: encouraging regeneration of oak in the forest. Though mature oak dominates the canopy in much of the forest, competition from species that tolerate shade has jeopardized the ability of oak to successfully regenerate. Since 1995, researchers have been collaborating with Forest Service managers, with funding from the Joint Fire Science Program (JFSP), to document the multiple effects of prescribed fi re on canopy opening, seedling recruitment, damage to mature trees, fuel loading, and effects …


Angle Of Repose: Testing Erosion And Prescribed Fire In Eastern Oregon And Washington’S Blue Mountains, Lisa-Natalie Anjozian Jan 2009

Angle Of Repose: Testing Erosion And Prescribed Fire In Eastern Oregon And Washington’S Blue Mountains, Lisa-Natalie Anjozian

Joint Fire Science Program Briefs (2007-2012)

Some forest lands in the United States are overgrown with small trees and thick with fuels. Prescribed fire has been used in many forests and woodlands to reduce fuel loads and the risk of wildfi re. But forests are unique, with different soils, plants, weather, and topography. While erosion from prescribed fi re would seem to be less severe than from a wildfire, prior to this study, little data existed on erosion rates and the infl uence of prescribed fi re on erosion in the Blue Mountains of eastern Oregon and Washington. This study showed that hillslope erosion in the …


Do Fence Me In: Cattle Enlisted In The Great Basin To Reverse The Cheatgrass/Wildfire Cycle, Elise Lequire Jan 2009

Do Fence Me In: Cattle Enlisted In The Great Basin To Reverse The Cheatgrass/Wildfire Cycle, Elise Lequire

Joint Fire Science Program Briefs (2007-2012)

Cheatgrass and cattle have co-existed in the Great Basin since the late 19th century, when both were introduced by settlers of the western territories. Unchecked grazing of the sagebrush-steppe community decimated the native perennial grasses in some areas and gave cheatgrass, a nonnative annual, permanent inroads into the ecosystem. Cheatgrass is generally palatable and nutritious for cattle in spring, but dries quickly in the hot, dry summers typical of the Great Basin, becoming a flashy fuel that carries fire quickly. The invasion has drastically shortened the fire return interval and led to increasingly intense and fast spreading wildfi res, which …


Wildland Fire Use: Managing For A Fire-Smart Landscape, Gail Wells Jan 2009

Wildland Fire Use: Managing For A Fire-Smart Landscape, Gail Wells

Joint Fire Science Program Digests

The promise of wildland fire use (WFU) is that, over time, the fires will play a more natural role, creating a jigsaw-puzzle pattern of burned and regrowing patches over a landscape and gradually moving it closer to the stand structure and species composition that prevailed before fire exclusion became the policy.
