Isn there something in the desert that eats buffelgrass?
Nope. There are no native grazers in the Sonoran Desert. Cattle will graze green buffelgrass, but have difficulty reaching it on steep slopes where the populations tend to start out. Jackrabbits have occasionally been seen gnawing on decadent culms and certain ant and rodent species may harvest the seed. None of these, however, will reduce or completely eliminate buffelgrass populations quickly enough to prevent infestations that increase the fire potential and associated risks to ecosystems and populated areas.
