We have lots of sheep here in Norway. We also have a few wolves, and sometimes they attack, killing and mutilate the sheep. We have a heated debate in Norway about having wolves in our fauna or not. I am stongly opposed to eradicate the wolf because there are alternatives to protect the sheep. I've read that in the United States and Canada they used the llama to protect sheep against predatores.
Taken from Wikipedia:
"Guard llamas may defend against predators in many ways. Llamas are instinctively alert and aware of their surroundings, and may draw attention to an intruder by making a startling alarm call. They may walk or run toward an intruder, and chase, paw at, or kick it. Some llamas may herd the animals they are guarding into a tight group or lead them away from danger and into their spot where they may feel the safest. Others may stand apart from the group and watch the intruder. Although llamas have been known to kill predators (such as coyotes), they should not be considered attack animals. They are generally effective against single intruders only, not packs. In the US, guard llamas have been most common in ranches located in western regions, where larger predators such as the coyote have been more prevalent.
Most research on the effectiveness of guard llamas has been done with sheep. A 1990 study by Iowa State University found that 80 percent of sheep producers with guard llamas rated them as effective or very effective. The study found that average rates of loss to predators fell from 21 to 7 percent after the introduction of a guard llama. In other studies, over half of guard llamas completely eliminated losses due to predators. Dogs and coyotes have been injured and even killed by llamas."
