The U.S. Fish and Wildlife Service (FWS) is poised to propose a listing decision for the Greater Sage Grouse under the Endangered Species Act by 2015. Eleven states are host to habitat for the species, and the FWS has indicated its intent to make a single range-wide listing decision, rather than a state-specific determination. Federal, state, local, and private entities have become actively involved in activities to conserve GSG habitat in an effort...

Over the last 30 years declines in greater sage-grouse populations have occurred across much of their range. Breeding populations had declined by an estimated 17-47% since the mid 1970s, a trend that has paralleled significant changes in the sagebrush habitats essential for the species. The primary factors affecting this change in sagebrush habitats differ by region and state but include changes in fire regime, conversion to cropland and seeded grasslands,...

The Colorado Division of Wildlife (CDOW) proposes to conduct a study of the Parachute/Piceance/Roan (PPR) population of greater sage-grouse during 2007 and 2008. The PPR is one of several small, spatially fragmented populations of sage-grouse in Colorado. The CDOW is interested in working with energy companies and other land owners and managers in the PPR area to sustain the PPR grouse population and plan for future management actions. The objectives...
