Burned and unburned sites (4 ha each) of black and white spruce in interior Alaska were studied in 1993 and 1994 within and adjacent to an area burned by wildfire in 1990. The main purpose of the research was to quantify fuel consumption and carbon release during the fire.…

Prescribed fire helps to maintain wilderness in its natural state, but it may result in air quality impacts that are unacceptable. This paper examines existing and proposed air quality regulations and how they may affect the use of prescribed fire in wilderness. It also…

An atmospheric general circulation model (AGCM) has been initialized with a 150 Tg summertime injection of smoke from post-war fires over Europe, Asia and North America. The smoke is subject to large-scale and convectice transport, dry deposition, coagulation and precipitation…

An improved method to estimate the amounts of carbon released during fires in the boreal forest zone of Alaska in 1990 and 1991 is described. This method divides the state into 64 distinct physiographic regions and estimates areal extent of five different land covers: two forest…

The character of most southern forest ecosystems has been shaped by fire. Indians and early settlers fired the woods for many purposes. After a period of attempted fire exclusion, foresters recognized the necessity of fire by prescription in southern pine cover types. This paper…

Atmospheric nitrogen deposition, associated with chronic urban air pollution, has produced stream water nitrate concentrations as high as 7.0 mg of N L^-l in chaparral watersheds in the San Gabriel Mountains of Los Angeles County, CA. Stream water [NO3-] and discharge were…

As part of the FOS-DECAFE experiment at Lamto (Ivory Coast) in January 1991, various aerosol samples were collected at ground level near prescribed fires or under local background conditions, to characterize the emissions of particulate matter from the burning of savanna…

Fire strongly influences carbon cycling and storage in boreal forests. In the near-term, if global warming occurs, the frequency and intensity of fires in boreal forests are likely to increase significantly. A sensitivity analysis on the relationship between fire and carbon…
