Praxelis clematidea (Praxelis; Asteraceae), a native of South America, was first discovered in Florida in Orange County in 2006; it has now been confirmed in 6 other counties: Hardee, Hillsborough, Lake, Manatee, Osceola, and Polk counties. These populations are concentrated around the Lake Wales Ridge (LWR) region and may pose a threat to the already imperiled flora and fauna of the LWR. An assessment of the threat to the LWR and other Florida ecosystems is essential, and control methods must be evaluated for Florida before the species becomes an insurmountable problem. Our goal is to inform the people of Florida of the threat of Praxelis and to urge them to report any populations so they can be controlled or eradicated.
