 Ranchers will tolerate elk 1 as long as they don't compete too much with their cattle.  But as the elk move in, their old enemy follows them out of Yellowstone, an animal that's more difficult for ranchers to accept. 


 
In their minds, fear of the wolf runs deep, even Yellowstone lost its wolves. They were wiped out over 80 years ago. After years of prejudice, they were reintroduced in 1995, brought back by the authorities to restore Yellowstone's natural balance. But the wolves have done so well that now they are moving out of the park, looking for new territories and prey 2. Out here, it's clearer to see why wolves have a bad reputation.
 
If ranchers' cattle are at risk, by law wolves can be shot. As wolves come back, ranchers are being forced to return to the old ways to get back into the saddle and protect their herds 3
 
But opinion is changing. Working with scientists who have radio-collared the Yellowstone wolves, ranchers can now keep track of them, and when they know they are near, shoot not to kill but to scare them away.
