One summer, over a decade ago, biologists discovered that gray wolves - once driven to near-extinction in the continental United States - were breeding again in Washington state. The sound of howling wolf pups was welcome news for conservationists, but not for the state’s current $700 million cattle industry. Not long after, when some wolves began to prey on livestock, age-old tensions were resurrected. Some members of that first pack were poached - despite federal protections. Ranchers whose forefathers believed a good wolf was a dead one now had to contend with government officials and conservationists who had other opinions.
