The U.S. Forest Service is illegally jeopardizing a small herd of bighorn sheep with deadly diseases by allowing thousands of domestic sheep to graze in eastern Idaho as part of agricultural research activities, environmental groups have said in a lawsuit.

Western Watersheds Project and WildEarth Guardians in the lawsuit filed Tuesday contend the grazing of sheep owned by the University of Idaho via permits issued to the U.S. Department of Agriculture's Sheep Experiment Station risks transmitting diseases to bighorn sheep.

An environmental group has filed an appeal seeking to stop the construction of two high-voltage transmission lines in southwestern Idaho.

Western Watersheds Project filed the appeal late last week with the U.S. Department of the Interior's Board of Land Appeals concerning the Gateway West project.

The U.S. Bureau of Land Management last month issued a formal decision approving a plan by Idaho Power and Rocky Mountain Power to build and operate 321 miles of 500-kilovolt transmission lines on public land in Idaho's Gooding, Elmore, Owyhee, Cassia and Twin Falls counties.

A proposed fuel break system in southwest Idaho, southeast Oregon and northern Nevada will limit the size of destructive rangeland wildfires and protect habitat for sage grouse, say officials with the U.S. Bureau of Land Management.

The agency on Tuesday released a plan called the Tri-State Fuel Break Project, which would create gaps in combustible vegetation along existing roads on public lands in the three states by reducing fuel next to the roads, using either machines or chemical treatments, and maintained with a long-term schedule.

A conservation group has filed a lawsuit contending the U.S. Forest Service is violating environmental laws by issuing grazing permits to central Idaho livestock growers with a long history of violating permit restrictions.

Western Watersheds Project in the lawsuit filed Wednesday says the Forest Service is issuing the permits knowing cattle grazers aren't following guidelines in the area that also includes the newly-formed White Clouds Wilderness.
