Currently, air quality in the immediate areas surrounding the fire is poor, while surrounding areas seem to be largely OK, according to data from the U.S. Environmental Protection Agency (EPA ...
Although recent air-quality index readings would appear to be safe, officials are cautioning that some wildfire ash is too large to be detected by their instruments and will not be captured by air ...
A wildfire, forest fire, or a bushfire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. [1] [2] Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire (in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld ...
Fire ecology is a scientific discipline concerned with the effects of fire on natural ecosystems. [1] Many ecosystems, particularly prairie , savanna , chaparral and coniferous forests , have evolved with fire as an essential contributor to habitat vitality and renewal. [ 2 ]
Compared to the preindustrial era, wildland land fire in the conterminous U.S. has been reduced 90 percent with proportional reductions in wildland fire emissions. Land use changes (agriculture and urbanization) are responsible for roughly 50 percent of this decrease, and land management decisions (land fragmentation, suppression actions, etc.) are responsible for the remainder.
Toxic wildfire smoke triggered an air quality health advisory for the New York City metro region on Saturday, impacting millions of people and underscoring climate change’s rising threat to ...
Large fires in Alberta, British Columbia and Saskatchewan are likely to keep churning out smoke throughout the summer and possibly into early fall, said Montana Department of Environmental Quality ...
Unplanned fires that escape suppression often burn under extreme fire weather and can have severe wildfire effects. In contrast, prescribed burns and managed wildfires generally burn under more moderate weather conditions and contribute to variable fire effects and surface fuel reduction that can mitigate future wildfire severity
