Andean bear–livestock conflicts: a review

  title={Andean bear–livestock conflicts: a review},
  author={Isaac Goldstein and Susanna Paisley and R.B. Wallace and Jeffrey P. Jorgenson and Francisco Cuesta and Armando Castellanos},

Andean bears are perceived as livestock predators where herding is common; bears are frequently blamed for any livestock disappearance or death. This negative perception often leads to the poaching of Andean bears by local residents and to a…
