A group of six environmental organizations have filed a lawsuit in Federal Court in Boise maintaining the US Sheep Experiment Station near Dubois, Idaho threatens the population of grizzly bears in the Greater Yellowstone Region. The Cottonwood Environmental Law Center was joined by five other groups in a lawsuit against the US Fish and Wildlife Service, the Department of Agriculture and the Agricultural Research Service saying the sheep station is too attractive for grizzly bears, which are diverted from their natural predation cycle to take advantage of free meals on sheep. The research center has been in that location since 1918 providing studies on sheep reproduction, genetics, growth and development, range management, and quality of meat and wool. Fish and Wildlife issued a biological opinion on Nov. 8, 2011, claiming that “the adverse effects were not likely to jeopardize the grizzly bear. However, the groups bringing the lawsuit claim that the Sheep Station never prepared an environmental assessment or impact statement as required under the National Environmental Policy Act. The lawsuit was prompted by the death of a collared grizzly bear they say took place on sheep station property last September.
