Chasing the lion's tail. The value of program review: a case study from the management of Leonotis nepetifolia (L.) R.Br. in Rinyirru (Lakefield) National Park.

The annual herb Leonotis nepetifolia (lion’s tail) has been present in Rinyirru (Lakefield) National Park on Cape York Peninsula since at least the earlyto mid-1980s and has been the target of control action for at least 17 years. A review of the program was conducted in 2010. The program is notable for the sustained effort that has been made but the review concluded that eradication was unlikely without some modification of the approach. There was a need for improved delimitation and a shift in where efforts were concentrated. A five-year plan was devised with the aim of eliminating three small outlying infestations whilst containing two larger infestations in the short term. Subsequently, capacity and approach to eliminate the main infestations could be determined.
