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.

Managers must also take into account, however, how invasive and non-native species respond to fire if they want to restore the integrity of a native ecosystem. For example, fire can only control the invasive spotted knapweed (Centaurea maculosa) on the Michigan tallgrass prairie in the summer, because this is the time in the knapweed's life ...
[1] [11] [12] By the latter half of the 20th century, many researchers had rediscovered both the prehistoric use of fire and methods to practice burning, but by then almost all prairie and grassy woodlands had been converted to agriculture or succeeded to full-canopy forest.
Fire started by lightning has always been a part of the natural life cycle in the Western U.S., and for centuries Native Americans also carried out controlled burns, referred to as cultural burns ...
Fire behavior associated with persistent drought, high winds and column-driven spread are associated with higher burn severity in western North American forests. However, strong scientific evidence across dry and moist mixed conifer forests demonstrates effectiveness at mitigating burn severity, often even under extreme fire weather conditions
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 ...
These were in a fire ecology of open grassland and forests with low ground cover of herbs and grasses. The frequent fires which maintained the woodlands were started by the region's many thunderstorms and Native Americans, with most fires burning the forest
Fire adaptations are traits of plants and animals that help them survive wildfire or to use resources created by wildfire. These traits can help plants and animals increase their survival rates during a fire and/or reproduce offspring after a fire. Both plants and animals have multiple strategies for surviving and reproducing after fire.
