Recent wolf kills alarm activists (1/3ページ)

The killing of 20 wolves in the Rockies since the animals lost endangered status is an unprecedented death toll that must be stopped in court, environmentalists say.

"There's a great sense of urgency," says Michael Robinson, a wolf expert at the Center for Biological Diversity, one of several groups that plan to file a lawsuit this month. "The wolf population is being gunned down right now."

Wildlife officials say the number of wolves killed in the past two weeks is small compared with the 1,500 that are roaming the Rocky Mountain states. They say the wolves are plentiful and will remain so.
