A wildfire, sometimes known as a forest fire, is an uncontrolled fire in wildland often caused by lightning, human carelessness or arson. Ecologists today consider wildfires part of wildland ecosystem. Some plants have evolved to survive fires. Fire tolerant traits in some plants, when their habitat is exposed to fire, allow them to gain dominance over less fire-tolerant species. Photo credit: John McColgan, US Forest Service |
