Postage stamps issued to honour Trained Dogs who helped to Saved Macquarie Island by playing a vital role in intensive pest eradication campaigns.
Macquarie Island has significant biodiversity and is one of the few breeding locations for fauna in the Southern Ocean sector of the Pacific.
Introduced non-native species have had a serious impact on its natural flora and fauna.
In an effort to address this, Macquarie has been the focus of two intensive pest eradication programs in recent years: the first, to rid the island of cats, and, more recently, to rid it of rabbits, ship rats and mice.
Trained Dogs that Saved Macquarie Island
Dogs have played a vital role in these campaigns. In December 2002, two dogs and several handlers ensured that all cats had been eradicated from the island, after scouring it for any last sign.
Similarly, after an aerial baiting program in 2011, 12 rabbit detector dogs, including springer spaniels, labradors and one terrier-cross, covered more than 90,000 kilometres in their search for any sign of surviving rabbits.
The subantarctic Macquarie Island is a harsh environment for both humans and their canine companions.
The dogs were highly trained to ensure they would not be distracted by native animals, such as penguins and seals.
They were chosen for their tolerance to the cold, wet climate and for their superior work ethic.
Three rodent detection dogs (terriers) and their two handlers joined the search in 2013, and in 2014, the eradication program was declared a success.
The World Heritage–listed Macquarie Island has thus entered a bright new era, free of the devastating impacts of pests for the first time in more than 100 years.
The project is reported to be the largest successful island pest-eradication program ever attempted.
