The effects of wildfire and logging on erosion from two small catchments of the Pine Creek drainage in Idaho, USA, were investigated. One catchment was clearfelled in 1972 and a wildfire burned in the study areas in 1973. The fire was more intense…

Distribution of nutrients after the Entiat fire in north central Washington was examined. This intense fire produced an average ash weight on the soil surface of 2900 kg/ha. The ash layer contained 23 kg/ha N, 314 kg/ha Ca, 54 kg/ha Mg, 70 kg/ha K,…

Twenty-nine journals and diaries were reviewed for their vegetation descriptions of the sagebrush-grass area in an attempt to assess the relative importance of herbaceous plants and woody brush in the northern Intermountain West. The early writings…

Wildfires play a multiple role in the distribution of dwarf mistletoes - they may either inhibit or encourage these parasites depending primarily on the size and intensity of the burn. Many reports suggest that fire exclusion policies of the past…

Seventy-three clearcuts in western larch/Douglas-fir forests of western Montana were broadcast burned over a wide range of environmental conditions for the purpose of quantifying fire characteristics and burn accomplishment. The moisture content of…

Three cutting units of varying size, soil, and aspect located along streams in the Priest River Experimental Forest in northern Idaho were chosen for evaluation of changes in water quality caused by clearcutting and subsequent burning of slash.…

Establishment of western larch (Larix occidentalis Nutt.) seedlings is favored by site preparation that reduces both the duff layer and the sprouting potential of competing vegetation. A cooperative study of the use of fire in silviculture in…

Reports a first attempt to provide a computation system that will permit a rapid estimate of the amount of hazard to game fish caused by release of fire retardant chemical into streams. Field measurements necessary for application of the system are…

Contains 910 sets of forest fire ecology questions mailed to the authors by 302 land managers and scientists throughout the western United States and Canada. Questions were submitted in response to a survey of important research needs for…

For many years there has been much interest in moisture studies of forest fuels. The study reported here was in its 17th year when the author became involved. The study was terminated 2 years later. All data were compiled, adjusted, and analyzed; a…

A comparison of streamflow records from three small mountain streams in north-central Washington before, during, and after a severe forest fire showed three immediate effects of destructive burning. These were: Flow rate was greatly reduced while…

The concept of forest fire is especially difficult to deal with in an objective manner because fire has deep psychological associations for most animals, especially man. Moreover, attitudes toward forest fires have been greatly conditioned by what…

In 1966, preliminary results of this study were reported by Lyon in Research Paper INT-29, Initial Vegetal Development Following Prescribed Burning of Douglas-fir in South-Central Idaho. Because of a misplaced decimal point in that report, data for…

This study was undertaken to determine the thermal properties of, and the pyrolysis products from, western cottonwood (Populus trichocavya) and two of its major components: cellulose and xylan. The modifications due to treatment of the wood and its…

The moisture, ether extractive, and energy content of ponderosa pine (Pinus ponderosa Laws.) and Douglas-fir (Pseudotsuga menziesii L.) foliage were measured during two fire seasons. The moisture content of l- and 2-year-old needles was found to…

This work was undertaken because of a mutual interest of the Department of Defense, Advanced Research Projects Agency (ARPA), and the USDA Forest Service in the problems of detecting hot targets against natural terrain backgrounds using airborne…

Recreationists or city dwellers are usually most often thought of as being responsible for starting forest fires. But a limited study showed that fire starters were more apt to be people who lived near and worked on the National Forests. They were…
