Cenchrus ciliaris
It spreads very quickly and will often kill local native plants such as palo verdes by taking away nearby water. This plant has a very low ignition threshold and can burst into a raging flame even during the peak growing season. Its flammability and quick regrowth allow it to compete successfully against almost all vegetation in this region.[3]
Cenchrus ciliaris has become naturalised and often an invasive species in Australia, the southwestern United States, Hawaii, Mexico, Central America, South America, and Macaronesia.[1] In the Sonoran Desert it was introduced for erosion control. In the Mexico part of the Sonoran Desert it is still being planted and irrigated for livestock grazing.
