South Georgia 2011/2013/2015
South Georgia Heritage Trust, a Dundee based conservation trust, planned a multi -phase operation to eradicate invasive species from the South Atlantic Island of South Georgia.
Due to the very remote location and the long operational period, a decision was made to purchase helicopters to carry out the work.
Two Bolkow BO 105 helicopters were purchased from Bond Aviation in the UK and Phase One was completed in 2011. This Phase treated an area of 15000ha encompassing the Greene, Thatcher and Mercer Peninsular’ in the central part of the island.
One application of 2.5kg/ha was applied to all ground not covered in snow or ice with a second application of 3.5kg/ha treating all area with vegetation.
A gap of two years between phases was proposed to establish any potential effects on non-target species.
SGHT purchased a third BO 105 to complete the next two phases with Phase Two being carried out in autumn/winter 2013 and treating 60000ha on the north western part of the island and using the same bait application rates as previously.
Phase Three was carried out in 2015 and treated the south eastern part of the island.
