Laboratorys studies were conducted to determine the acute toxicity of three fire retardants (Fire‐Trol GTS‐R, Fire‐Trol LCG‐R, and Phos‐Chek D75‐F), and two fire‐suppressant foams (Phos‐Chek WD‐881 and Ansul Silv‐Ex) to early life stages of chinook…

We have developed a spatial database of historic natural fire regimes for the eleven western States to provide information in support of expected national increases in prescribed burning. Fire regimes are described in terms both of frequency and…

Fuel and vegetation spatial data layers required by the spatially explicit fire growth model FARSITE were developed for all lands in and around the Selway-Bitterroot Wilderness Area in Idaho and Montana. Satellite imagery and terrain modeling were…

In 1988, fires killed extensive lodgepole pine (Pinus contorta Dougl. ex. Loud) in Yellowstone National Park. This species bears both serotinous and non-serotinous cones, with the former most common in fire-origin stands of an even-aged character.…
