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 ]
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 ...
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]
Wildfire recovery strategies are dependent on the intensity of the fire (scale of low to high), which determines the extent of fire damage and effective forest restoration. Low intensity fires consist of minimal damage to small trees without burning all of the forest and the majority of leaves still remain on the trees.
The treacherous combination of rising temperatures and dried-up fuels has made Canadian forest much more prone to severe wildfires in recent decades, a new study has found. Driving these dangerous ...
Fire regimes of United States plants. Savannas have regimes of a few years: blue, pink, and light green areas. When first encountered by Europeans, many ecosystems were the result of repeated fires every one to three years, resulting in the replacement of forests with grassland or savanna, or opening up the forest by removing undergrowth.

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.
More importantly, fires have long-term effects on the post-burn environment. Fires in seldom-burned rainforests can cause disasters. For example, El Niño-induced surface fires in central Brazilian Amazonia have seriously affected the habitats of birds and primates. [22] Fires also expose animals to dangers such as humans or predators.
