• Fox baiting: NSW National Parks and Wildlife Service is carrying out an ongoing baiting program at North Head Sanctuary to control foxes for the protection of native fauna including threatened species such as Long-nosed Bandicoots and Little Penguins. The program uses manufactured baits, fresh baits and Canid Pest Ejectors containing 1080 poison (sodium fluoroacetate). Warning signs are located at the entries to sites being baited. Visitors are advised not to touch the baits or ejectors. Further, pets may be affected (1080 is lethal to dogs and cats) and are not permitted at North Head Sanctuary. Working dogs must be restrained or muzzled in the vicinity and must not enter the baiting locations. Penalties apply for non-compliance. In the event of accidental poisoning, seek immediate veterinary assistance. For further information, please call the Harbour Trust on (02) 8969 2128.
