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 ...
Following the same tone of timber resource protection, the U.S. Forest Service adopted the "10 AM Policy" in 1935. [3] Through this policy, the agency advocated the control of all fires by 10 o'clock of the morning following the discovery of a wildfire. Fire prevention was also heavily advocated through public education campaigns such as Smokey ...
Fire history, the ecological science of studying the history of wildfires, is a subdiscipline of fire ecology.Patterns of forest fires in historical and prehistorical times provide information relevant to the vegetation pattern in modern landscapes.
Many of these fires did not extinguish fully, but rather smouldered as overwintering fires (also called "zombie fires"). Droughts, combined with longer and hotter summers, dry out organic material in soils and make these types of fires more common in the country's boreal forests .

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]
The Meridian Boundary Fire burned 8,586 acres near Grayling, Michigan in 2010.. The U.S. state of Michigan has been the site of several major wildfires.The worst of these were in the lumbering era of the late-1800s when lumbering practices permitted the buildup of large slash piles and altered forest growth patterns which may have contributed to size of the wildfires.
In Australia, the prevalence of eucalyptus trees that have oil in their leaves results in forest fires that are noted for their extremely tall and intense flame front. Hence the bush fires appear more as a firestorm than a simple forest fire. Sometimes, emission of combustible gases from swamps (e.g., methane) has a similar effect.
