Creator:: Doherty, Kevin E., Tack, Jason D., Evans, Jeffrey S., and Naugle, David E.
Abstract:: A major goal in greater sage-grouse (Centrocercus urophasianus, hereafter ‘sage-grouse’) conservation is to spend limited resources efficiently by conserving large and functioning populations. We used maximum count data from leks (n = 4,885) to delineate high abundance population centers that contain 25, 50, 75, and 100% of the known breeding...

Creator:: Sage Grouse Initiative
Abstract:: In the northeast part of sage grouse range, 70% of the best habitat is privately owned – and the single greatest threat in this region is cultivation of native sagebrush grazing lands. Scientists assessed lands in eastern Montana, the western Dakotas, and northeast Wyoming to evaluate potential impacts to sage...

Creator:: Sage Grouse Initiative
Abstract:: Research evaluating effects of livestock grazing on greater sage-grouse nest survival suggests that a variety of locally-appropriate range management strategies support grouse populations. A new Montana study comparing effects of specialized grazing systems on ranches enrolled in the NRCS-led Sage Grouse Initiative (SGI) to ranches not enrolled in SGI grazing...
