Atlantic Territories Workshop 2

Completing horizon scanning for the Atlantic territories

A team of 16 people headed out to St Helena Island in November to carry out the final tranche of horizon scanning for the Atlantic territories: St Helena Island, Ascension Island and Tristan da Cunha. The workshop was hosted by the Agriculture and Natural Resources Division of the St Helena Government (SHG), with participants including the international team led by Prof Helen Roy from the Centre for Ecology and Hydrology, and local experts from SHG, the St Helena National Trust and independent consultants.
Following orientation field trips to Diana’s Peak National Park, the agricultural zones and the coastal marine area, a two-day workshop was held to identify the priority species not present in St Helena and with a high likelihood of arrival within the next 10 years. A total of 55 species were identified: 8 marine species, 19 plants, 21 invertebrates, and 7 vertebrates.

Teleconferences were held with teams on Ascension Island and Tristan da Cunha as delegates had been unable to travel to St Helena for logistical reasons. Lists of priority species have been provisionally identified for each Territory, with a total of 42 species for Ascension and 58 species for Tristan, covering all taxonomic groups and including both terrestrial and marine species.

As for the previous territories, pathways of entry for each species have been identified and pathway action plans are being drafted. Lists for all three territories are currently under review by the panel of experts, and the work will continue over the subsequent months, finalising the list of priority species and developing cost-effective actions to reduce the threat of each pathway.
