BILLINGS, Mont. - Wolves have killed more livestock north of Reed Point in Montana, despite efforts to remove the animals from the area.

Federal Wildlife Services officials say wolves killed two sheep and badly injured a ewe and a goat on a ranch north of Reed Point that has lost 20 animals to wolves since September. The injured animals were not expected to survive.

The rancher has a state permit to kill one wolf and FWS trappers continue to search for wolves, as well.

Montana wildlife officials believe two wolves were responsible for killing livestock on two ranches in the Reed Point area. Wildlife Services tracked down and killed one of the wolves on Nov. 28.
