The suppression of fire can lead to unforeseen changes in ecosystems that often adversely affect the plants, animals and humans that depend upon that habitat. Wildfires that deviate from a historical fire regime because of fire suppression are called "uncharacteristic fires". [citation needed]
The five federal regulatory agencies managing forest fire response and planning for 676 million acres in the United States are the Bureau of Land Management, the Bureau of Indian Affairs, the National Park Service, the United States Forest Service and the United States Fish and Wildlife Service.
Prevention policies must consider the role that humans play in wildfires, since, for example, 95% of forest fires in Europe are related to human involvement. [119] Wildfire prevention programs around the world may employ techniques such as wildland fire use (WFU) and prescribed or controlled burns.
Human-caused fires are also responsible for 97% of wildfires that threaten homes. People often start wildfires through dangerous actions, including open burning, campfires, firearms and equipment use.
Nearly 85% of U.S. wildfires are caused by humans, according to the U.S. Forest Service. Natural causes include lightning and volcanic activity. The Hawaiian Islands have six active volcanoes ...
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.

When I arrived, the burn's incident-management team had already put together a burn plan detailing our objectives — reducing wildfire risk to the landowner's house, thinning small tree saplings ...
The Grass Fire (1908) by Frederic Remington depicts Native American men setting fire to a grassy plain. Native American use of fire in ecosystems are part of the environmental cycles and maintenance of wildlife habitats that sustain the cultures and economies of the Indigenous peoples of the Americas. Indigenous peoples have used burning ...
