A Working for Water funded programme was set up within SANBI to investigate invasive alien plants that stand a chance of being eradicated from South Africa. We report here on two years progress with clearing six plant species occurring in KwaZulu-Natal. Three of the species, pompom weed (Campuloclinium macrocephalum), Formosa lily (Lilium formosanum) and Parthenium hysterophorus populations occurring south of Richard’s Bay, were cleared for historical reasons. They had been cleared in previous years by a provincial programme and the funders requested that the SANBI programme continue these containment efforts. Since its inception in 2008 the programme has gathered data on a number of species and three of these, Sagittaria platyphylla, Hypericum pseudohenryi and Furcraea foetida, were also targeted for clearing in KZN during the summer of 2011/12. The clearing effort has been combined with detailed data collection and awareness raising of interested stakeholders which has resulted in a significant increase in the recorded localities of the species. The experience with these six species clearing programmes has provided some initial lessons as to how in practice we can assess progress towards management goals (specifically whether eradication or containment is feasible).
