SPOKANE, Wash. -

Wolf advocates are outraged that the state is preparing for the second time to exterminate a wolf pack for preying on livestock in northeastern Washington.

This is the second time in four years that a pack of endangered wolves has received the death penalty because of the grazing of privately owned cattle on publicly owned lands.

Washington is home to about 90 wolves, and killing the 11 members of the Profanity Peak pack amounts to 12 percent of the population, according to the Center for Biological Diversity.

Last week, the Washington Department of Fish and Wildlife announced to would exterminate the Profanity Peak pack in Ferry County. Since mid-July, the agency has confirmed that wolves have killed or injured six cattle and probably five others, based on staff investigations.
