Pennisetum ciliare

Buffelgrass loves south-facing hillsides in the Sonoran Desert, especially in Sonora. In some cases it replaces nearly all native vegetation except older trees and cactus that persist from before the invasion took place.

This area was cleared and tilled for buffelgrass. Now it is a virtual monoculture of buffelgrass, which provides poor forage for cattle, the whole point of the operation.
