The dollar and nondollar effects of alternative levels of residue utilization in mature lodgepole pine are compared. Net dollar returns were greater in conventional logging (removal of green sawlogs to a 6-inch top, with slash piled and burned) than…

Height of slash fire smoke columns, commonly thought to be a function of atmospheric conditions alone, through a series of 10-acre experimental fires is shown to be strongly related to fire intensity. By conducting intense fires, land managers can…

A recent large-scale study of prescribed broadcast burning in western Montana required the development of a system for inventory of clearcut logging slash furls before and after fire treatment. The system is best suited for inventorying material…

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…
