Cheatgrass, pictured here, is an introduced invasive plant species from Eurasia which does not have known native predators in the arid and semi-arid ecosystems of Western North America.
The mechanical implement, designed and applied by Antelope Mine, was used in place of fire to remove the cheatgrass, duff, and litter layers.
