Interpretive Summary: Restoring medusahead-infested native communities may be most successful if there is enough remnant native vegetation to eliminate the need for revegetation efforts. Prescribed burning followed by imazapic (Plateau®1) application provided the best control of medusahead and resulted in the greatest increases in native vegetation density, cover, and diversity. Native vegetation can be at least partially restored in medusahead infestations by selectively controlling medusahead without implementing seeding treatments.
