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 ]
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.

A fire regime is the pattern, frequency, and intensity of the bushfires and wildfires that prevail in an area over long periods of time. [1] It is an integral part of fire ecology, and renewal for certain types of ecosystems.
Plants in wildfire-prone ecosystems often survive through adaptations to their local fire regime. Such adaptations include physical protection against heat, increased growth after a fire event, and flammable materials that encourage fire and may eliminate competition .
Broad-scale evidence of fire exclusion is strong across disciplines and western forest ecosystems. Although high severity fire was a component of many historical fire regimes, the frequency and extent of high severity fire over the past few decades is outside the range of historical range of variability
Hypothesized fire regimes of natural communities in the United States. Grassy woodlands have regimes of a few years: blue, pink, and light green areas. Pre-Columbian woodlands of North America , consisting of a mixed woodland-grassland ecosystem, were maintained by both natural lightning fires and by Native Americans before the significant ...
Fire Adapted Communities logo. A fire-adapted community is defined by the United States Forest Service as "a knowledgeable and engaged community in which the awareness and actions of residents regarding infrastructure, buildings, landscaping, and the surrounding ecosystem lessens the need for extensive protection actions and enables the community to safely accept fire as a part of the ...
