This research evaluates the impact of wild dogs on beef cattle
calves in extensive grazing systems. Although annual calf loss
caused by wild dogs can be as high as 32%, in most years predation
loss could not be detected. Surprisingly, calf predation was higher
and occurred more often where baiting had occurred compared to
adjoining areas where baiting had not occurred. I speculate that
dispersing wild dogs that re-colonise baited areas kill more calves
than wild dogs in stable packs because they lack the group hunting
skills and group size to efficiently switch to larger (kangaroo)
prey when smaller, preferred prey become unavailable (especially
during drought). 1080 baiting programs had no detectable short or
long-term impact on reptile, bird, feral cat or native carnivore
activity. These data show that while wild dogs have significant
capacity to prey on beef cattle calves, wild dog control is
unnecessary provided alternative prey resources are available and
wild dogs are in stable populations. Coordinating control at a
regional level to avoid wild dogs re-colonising is only beneficial
in years, seasons or situations of low, preferred-prey
availability.
