Enhancing invasive alien plant eradication outcomes: Lessons learned from South Africa

Several attempts to eradicate invasive alien species have been initiated in South Africa and despite no formal eradication declaration, several species have been brought down to low levels or are now absent from the country. Based on an expert workshop with South African implementing agencies on best nationwide eradication practices, we recommend that eradication programmes should be well coordinated, and characterised by collaboration between implementing agencies, researchers and practitioners. Countries should have a list of eradication targets informed by the best available science, with targets ranked according to priority. The best eradication model should be used consistently until eradication is achieved. While most of these priority areas are not novel, it does provide a perspective from a biodiverse African country with limited funding, based on 16 years of experience in implementing eradication programmes. It corroborates challenges experienced elsewhere in the world and contributes to enhancing eradication outcomes globally.
