Since the completion of the South
Atlantic Invasive Species Project in 2009, multiple projects have been carried out with similar aims to address invasive species in the region. For example, in 2011, the Department for the Environment, Food, and Rural Affairs initiated a series of projects to address

A survey conducted in 2009 by Jo
Osborne, Renata Borosova, Marie Briggs and Stuart Cable recorded 24 introduced vascular plant species on South Georgia. A report on the survey recommended the eradication of 20 out of 24 of these species. The report also recommended further survey to map the extent of

In 2010, a South
Atlantic Invasive Species Strategy and Action Plan was developed from the project findings. The aim of this was to encourage continuation of work after the project was completed and to act as the basis of a regional approach to invasive alien species. To implement the key actions of

Saint Helena’s wildlife has been ravaged by species introduced to the island. Goats, gorse, grasses, and cage birds have all been liberated on the island where they have wreaked havoc with the native species. Saint Helena is a noted extinction hotspot, driven largely by non-native species, and the

The project involved surveys to identify and map naturalised and cultivated taxa, as well as risk assessment of introduced species and targeted control of some species.
