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 ...
Although other characteristics of a forest will influence the impact of fire upon it, factors such as climate and topography play an important role in determining fire severity and fire extent. [39] Fires spread most widely during drought years, are most severe on upper slopes and are influenced by the type of vegetation that is growing.
In order to exercise efficient emergency management, states susceptible to wildfires have collaborated to develop the Firewise Communities USA Recognition Program.The Firewise Communities Program focuses on reducing the loss of life and property, in terms of wildfires, by providing resources to allow communities to build responsibly in natural surroundings and assist one another in preparing ...
Also referred to as air attack. The use of aircraft in support of ground resources to combat wildfires, often most effective in initial attack in light fuels. air drop The delivery of supplies or fire retardant from the air. Supplies can be dropped by parachute, while retardant is generally released in a single drop of one or more trails, the size of which is determined by the wind and the ...
For example, the Forest Fire Emergency Fund Act of 1908 permitted deficit spending in the case of emergency fire situations. [3] As a result, the U.S. Forest Service was able to acquire a deficit of over $1 million in 1910 due to emergency fire suppression efforts. [3]
Because fire can reveal dormant seedlings, it is a land management tool. Fire was a part of the landscapes of Ontario until early colonial rule restricted indigenous culture in across Canada. [59] During colonization, large scale forest fires were caused by sparks from railroads and fire was used to clear land for agriculture use.
The "pyroCb" is a fire-started or fire-augmented thunderstorm that in its most extreme manifestation injects huge abundances of smoke and other biomass-burning emissions into the lower stratosphere. The observed hemispheric spread of smoke and other biomass-burning emissions has known important climate consequences.
