The Group was established in 1996 as a consultative group to guide and stimulate interest in the conservation of this species. In the last 10 years the activities of the group have grown considerably, including a range of educational and outreach initiatives, and research throughout the flyway in Iceland and Canada. As such we have established solid working relationships with individuals within the Canadian Wildlife Service, Greenland Institute of Natural Resources and Icelandic Institute of Natural History.
Why Brent Geese?
This population is from the breeding stock from the eastern high arctic islands of Canada which stage mostly in Iceland in spring and autumn. Ireland is especially important as a wintering ground as almost the entire population occur on the island during autumn and winter. Holding such a large proportion of this flyway population (probably 99% of the population stop or pass through Ireland), coastal sites all around Ireland are crucially important for this flyway population, and include notably Strangford LOugh and Lough Foyle (in Northern Ireland), Dublin Bay and approximately 20 additional sites around the coastline.
What we do
The Group is involved in a wide range of activities including: co-ordination of international annual censuses, co-ordination of an international ringing and resightings programme, applied research, and development and implementation of an AEWA Single Species Action Plan. Much of the work of the group is in support of the work programme which forms part of a WWT-led International Research programme funded and supported centrally by NPWS and EHS and in collaboration with IINH (Iceland) and CWS (Ottawa).

Branta bernicla hrota (hrota after an old Icelandic onomatopoeic name)
Not to be confused with: 2 other pale-bellied forms of Brent:
East Atlantic Brent (breeding Svalbard and NE Greenland, wintering Denmark and Lindisfarne, England) Eastern Low Arctic Brant (breeding low Arctic Canadian Islands of Baffin, Southampton, Foxe Basin, wintering Atlantic seaboard of N America)
and an intermediate form (between B bernicla nigricans and hrota)
Western High Arctic Brant (breeding western Queen Elizabeth Islands, incl. Melville and Prince Patrick, wintering on Pacific coast, mainly Puget Sound, Washington State)
