KM-C3 Eradication has been successful, 
especially for small and slow-spreading 
populations of invasive alien species in isolated 
ecosystems {C19}. Over the last 100 years, 88 per 
cent of eradication attempts on 998 islands have proven 
successful, especially for invasive alien vertebrates. 
Large-scale eradications have been achieved but in many 
cases are likely to be infeasible. There are also examples 
of eradication of invasive alien plants and invertebrates, 
particularly for those with limited distribution. Adoption of 
appropriate tools and technologies and involvement of 
relevant stakeholders underpin and improve the success of 
eradication programmes. Sustained investment is required
