Use taste-aversion to reduce predation of livestock by mammals to deter human-wildlife conflict Terrestrial Mammal Conservation

A replicated, before-and-after study in 1975–1976 on 16 pastures in Saskatchewan, Canada (Jelinski et al. 1983) found that use of lithium chloride-treated baits to induce taste-aversion, was associated with reduced predation of sheep by coyotes Canis latrans. Losses of sheep and lambs to coyotes fell from 4% (892 predated out of 22,407 animals) in 1975 (before baits used) to 1.5% (301 predated out of 20,574 animals) in 1976. Factors such as animal husbandry and use of other coyote control methods were not controlled for. Sixteen sheep pastures (mix of private ownership and community cooperatives), holding 101–4,543 sheep, on which predation by coyotes was previously reported, were studied. Baseline predation data were collected in 1975. In 1976, lithium chloride baits (which induce gastrointestinal discomfort) were used at all sites (bait application methods not detailed in paper).
