Kate Chamberlain, a wildlife rescuer, gives fluids to a dehydrated gray-headed flying fox in Yarra Bend Park.

It is illegal to keep or sell established pest animals such as foxes without a permit. Females were birthing pups as normal, says biologist Stephen Brend, who is in charge of monitoring gray-headed flying foxes in Victoria province, including at Yarra Bend Park, which is home to a significant colony of the bats.

This requires that working or pet dogs be prevented from roaming in areas where CPEs are active, so that they do not encounter and potentially trigger a CPE. Foxes were introduced by the early settlers around 1829. Baitingcan occur year-round, but the best results are achieved with an intermittent 'pulse' baiting pattern with poison baits in the ground for 1 to 2 months followed by 1 to 3 months of baits being removed.
