The FWS determined the range-wide listing was warranted because of habitat fragmentation, and the lack of a regulatory structure designed to protect habitat. Various “threats” to habitat were identified and discussed in the finding. As a result of the finding, the Bureau of Land Management (BLM), the U.S. Forest Service (USFS), the State of Utah and the other western states with sage-grouse habitat, have each initiated planning and other actions designed to mitigate the identified threats and protect important sagebrush habitats, develop adequate regulatory mechanisms, and thereby eliminate the need for a listing under the ESA. 2
Within Utah, Governor Herbert chartered a Working Group to develop recommendations for a statewide plan for the conservation of sage-grouse, while also providing for the continued economic health of the state.
The Working Group met in open, public meetings from late February to October of 2012. In addition to the recommendations of the Working Group, the Governor’s Office, through the Public Lands Policy Coordination Office, received comments and advice from other interested parties, including industry, environmental organizations and county commissioners.
