What is buffelgrass?

Buffelgrass is a perennial grass from Africa that is invasive to the Sonoran Desert of the Southwest United States, where it threatens desert ecosystems by out-competing native plants and altering fire regimes. It has the potential to transform the Sonoran Desert ecosystem from a diverse assemblage of plants to a grassland monoculture.

Buffelgrass was brought to Arizona in the 1930s for erosion control and began expanding rapidly in the 1980s. Left unchecked, buffelgrass will dominate the desert landscape and could enable regular, fast-moving wildfires.

USGS research shows that early treatment of areas invaded by buffelgrass can dramatically reduce the presence of this species.
