When you lose an animal to causes other than wolf predation, you usually find the carcass; wolves may not leave anything at all. “It’s like the animal evaporated. We get paid for confirmed kills, but not the ones that disappear or we find too late to determine cause of death,” Whittaker explains. Bruce Mulkey of Baker, ID, says wolf proponents on a panel discussion at Idaho State University last year claimed wolves were responsible for only 1% of livestock losses, and ranchers lose more calves to disease and other problems.
The reason the statistics are so low is explained here. But even if you take the 1% number, their are almost 5 million cattle in Idaho and Montana, that is still 50,000 head of cattle killed (http://beef2live.com/story-cattle-inventory-vs-human-population-state-0-114255). And that is just cattle, not all other livestock and pets.
This also shows what the opposition base everything off of, just numbers and hearsay. The author is obviously from a ranch back ground with the niche words she uses but she does report both sides. That is good to get rid of the stubborn farmer stereotype.
