WebOct 30, 2024 · FIRE RESEARCH Across the Western U.S., a history of fire management has altered wildfire patterns on public lands. As a result, more frequent or severe blazes have destroyed native vegetation and cleared a path for invasive plants, like the yellow cheatgrass pictured above, across many ecosystems. WebFire significantly affects soil properties because organic matter (OM) located on, or near, the soil surface is rapidly combusted. The changes in OM, in turn, affect several chemical, physical, and microbiological properties of the underlying soil. Although some nutrients are volatilized and lost, most nutrients are made more available.
