South Georgia (Islas Georgias del Sur)* in the South Atlantic supports introduced populations of three mammals: Reindeer Rangifer tarandus, Norwegian Rat Rattus norvegicus and House Mouse Mus musculus. Efforts to eradicate all three species commenced in 2011 and will continue at least into 2014. Removal of these three aliens is expected to improve the island's habitats for several species of seabirds, including ACAP-listed White-chinned Petrels Procellaria aequinoctialis.
Field work conducted during the 2011/12 austral summer season has been largely directed at assessing whether Phase One of the rat eradication programme conducted in 2010 has been successful and looking at aspects of the biology of the mouse population. A number of reports detailing these activities are now available on-line (click here for a list of relevant reports; those dated 2012 are listed below).
