It is a human problem that we would intentionally put imported and non-native livestock in areas that are a natural home to predators and then define the predators as problematic (HCN, 2/20/12, "Bears in sheepland"). As long as these sheep and grizzlies can share the same area without the bears being destroyed, keeping the Sheep Experiment Station may work. But it is not right to destroy a bear over an imported head of livestock -- cattle or sheep. We see the same situation with the bison: It's a very sad thing, to be sure, that cattle are prioritized over native bison for the sake of money.
