Excavation and burying of food items is a common behaviour in dogs and foxes. In Victoria burial of poisonous meat baits (containing 1080) to a depth of 8 – 10 cm for fox and wild dog control is a standard practice and is thought to provide some protection to non-target native animals. However, it has long been suspected that other animal species will take buried fox baits. To confirm this we opportunistically filmed the behaviour of free living bush rats (Rattus fuscipes) and southern brown bandicoots (Isoodon obesulus) at buried bait stations at two separate Victorian study sites. Both species were found to be capable of detecting and digging up meat baits buried at a depth of 10 cm. Our observations indicated that buried deployment may not always prevent these native species from direct access to poison baits laid for pest predator control.
