Fire is a fundamental component of the Longleaf Pine ecosystem. As land managers seek to restore the Longleaf Pine at sites throughout the South, prescribed fire will be an integral part of their plan. However, the effects of prescribed fire on air quality are a serious concern…

Anthropoeenic influences on recent tree mortality in mid-montane mixed conifer forests of southern California, USA, and northern Baja California, Mexico, were investigated. The Pinus jeffreyi-Abies concolor phase of the mixed-conifer montane community was sampled at three sites…

Early 1900 wildfires throughout much of the Adirondack Mountain landscape resulted in the prohibition of prescribed burns within the Adirondack and Catskill Parks boundaries and restriction of prescribed burning to only non-forested areas (i.e., grasslands) throughout the…

In California, the percentage of wildland which is prescribed burned has been declining for many years. Fear of litigation, environmental concerns, and public perceptions seem to be the stumbling blocks. Is the reverse true: if we stop prescription burning, will we alleviate our…

Managers of designated wilderness or conservation areas, especially those that are fire-dependent, often face a major dilemma. It is essential that fire perform its natural role of rejuvenating the ecosystem. Standards of environmental regulation, stewardship responsibilities…

The Fire Behavior Research Work Unit (RWU) of the Intermountain Research Station has been developing the Wildland Fire Assessment System (WFAS) since 1994. The WFAS will eventually combine the functionality of the current fire-danger rating system (Deeming et al. 1977) and the…

Anthropogenic activities of the past century have caused a dramatic increase in global air pollution. This process has accelerated in the past few decades, and emissions of carbon dioxide, nitrogen oxides, or chlorofluorocarbons caused serious changes in the earth's climate, e.g…

Smoke produced by vegetation fires consists of a complex mixture of gaseous, liquid, and solid phases. Many particulates are generated during vegetation fires. Crutzen and Andreae (1990) have estimated that global emissions of pyrogenic smoke particles (50-150 Tg yr-l) may…
