Wildland fire refers to a fire that occurs in an area of natural vegetation, such as forests, grasslands, or wetlands. There are several synonyms for this term, including bushfire, forest fire, grass fire, prairie fire, and woodland fire. Bushfires are typically used to describe wildfires in Australia, while forest fires are often used to describe larger fires that occur in heavily forested areas. Grass fires are commonly used to describe fires that occur in open grasslands and prairie fires are found in the Great Plains of North America. Woodland fires are often used to describe fires that occur in forests that have a mix of trees and undergrowth. Regardless of the term used, wildland fires are a significant threat to human life, property, and the natural environment.
