Executive Overview The Keppel Islands, which are located within Keppel Bay (adjacent to the Capricorn Coast in Central Queensland) were cut off from the mainland approximately 6 000 years ago. Brushtail possums (Trichosurus vulpecula) are native to the adjacent mainland area and have been introduced to four islands in the bay, one of which (Middle Island) is the proposed site for this possum eradication trial. In 2002 population estimates ranged from 4 - 11 animals per hectare (habitat dependant) on one of the islands (627ha North Keppel Island), compared to an average density on the adjacent mainland of 0.2 – 0.4 individuals per hectare (Strahan, 1995). Possums were most likely introduced to islands in Keppel Bay after European settlement as a harvesting source for pelts. Genetic analysis has not iden... ... middle of paper ... ...
