Where is grass typically found as a type of fuel?

Grass is typically found in desert and range areas, which are characterized by open landscapes and limited tree cover. These environments support grassland ecosystems where vegetation primarily consists of grasses and herbaceous plants. The fuel type in these areas is primarily grass, which can ignite and spread fire quickly due to its low moisture content and abundant availability during dry conditions.

In contrast, cold mountainous regions often have different vegetation types, such as conifers or shrubs, and may not support extensive grassy areas. Dense forested areas are dominated by trees and other forms of vegetation, providing a different fuel type that is not primarily grass. Swamps and marshlands usually contain moisture-rich vegetation, which can inhibit grass growth and support aquatic plants instead.

Understanding the environment in which grass thrives helps reinforce the link between fuel types and fire behavior, particularly how fire can spread rapidly in grass-dominated regions under certain conditions like dry weather and wind.
