Welcome to the Durban Early Detection and Rapid Response (EDRR) website
Preventing the introduction of invasive alien species is the first line of defence against invasions. Even the best prevention efforts will not stop all invasive species being introduced.
The second line of defence is early detection and rapid response (EDRR). EDRR efforts increase the likelihood that invasions will be addressed successfully, and help to prioritise both species and areas for remedial interventions. This is especially applicable for emerging weeds, which are those weeds whose populations are still localised and whose population levels are not beyond that which can be contained and possibly eradicated. Monitoring and Rapid Response in controlling such plant populations helps to avoid the long term costly operations required, and significantly helps to mitigate negative ecosystem impacts. The costs associated with EDRR, within a framework of adaptive management, are much lower and require less effort than those of long-term management programmes that deal with widely established invasive alien species.
