FLAGSTAFF, Ariz. (AP) - Environmentalists are suing the federal government to keep livestock away from rivers and streams in two national forests in New Mexico and Arizona.
The Center for Biological Diversity sued the U.S. Forest Service and the U.S. Fish and Wildlife Service this week.
The group argues the agencies aren't doing enough to ensure cows aren't pushing threatened and endangered species into extinction.
It's an argument the group made in a courtroom more than 20 years ago. In that case, the Forest Service agreed to remove cattle from much of the riparian areas across hundreds of grazing allotments.
