Cogongrass

Imperata cylindrica

Origin: Native to Southeast Asia

Impact: Cogongrass has been ranked as one of the ten worst weeds of the world. It can invade and overtake disturbed ecosystems, forming a dense mat that makes it nearly impossible for other plants to coexist. Large infestations can alter the normal fire regime of a fire-driven ecosystem by causing more frequent and intense fires that injure or destroy native plants.
