Pattern and process of prescribed fires influence effectiveness at reducing wildfire severity in dry coniferous forests

Year of Publication
2012
Publication Type

We examined the effects of three early season (spring) prescribed fires on burn severity patterns of summer wildfires that occurred 1–3 years post- treatment in a mixed conifer forest in central Idaho. Wildfire and prescribed fire burn severities were estimated as the difference in normalized burn ratio (dNBR) using Landsat imagery.

Mountain pine beetle attack alters the chemistry and flammability of lodgepole pine foliage

Year of Publication
2012
Publication Type

During periods with epidemic mountain pine beetle (Dendroctonus ponderosae Hopkins) populations in lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests, large amounts of tree foliage are thought to undergo changes in moisture content and chemistry brought about by tree decline and death. However, many of the presumed changes have yet to be quantified.

Estimation of Wildfire Size and Risk Changes Due to Fuels Treatments

Year of Publication
2012
Publication Type

Human land use practices, altered climates, and shifting forest and fire management policies have increased the frequency of large wildfires several-fold. Mitigation of potential fire behaviour and fire severity have increasingly been attempted through pre-fire alteration of wildland fuels using mechanical treatments and prescribed fires.
