Sage-grouse in Balance: Risks & rewards
Greater sage-grouse are vulnerable during the four weeks when eggs are in the nest and the days right after hatching. Females are focused on keeping eggs sheltered and warm, and only leave the nest once or twice a day for food and bio breaks.
If the canopy of sagebrush over the nesting site is not thick enough, a nest is at higher risk of being spotted from above or sniffed out at ground level by predators that are among the more than 350 other species native to sagebrush habitats.

In healthy habitat, sage-grouse can be shielded from predators like badgers, coyotes, golden eagles and other raptors. Ample native vegetation also guards against the heavy steps of elk, deer, pronghorn or livestock that may be in the area.
Things work differently when predators like foxes, skunks and ravens follow human activity into sagebrush areas they couldn't otherwise access. Roads, powerlines and other structures bring sage-grouse nests into the reach of these novel predators. Altered vegetation can also force hens to go farther from their nests to find something to eat, leaving eggs untended for longer periods of time.
Ravens keenly observe nesting hens' movements off their nests, which tend to happen at the same
times each day, to learn when eggs might be unguarded. | BLM-Oregon/Washington / Greg Shine
Stopping the decline of sage-grouse populations cannot be achieved solely by reducing or removing predators. The BLM manages wildlife habitat and does not have authority to undertake or require direct actions to control predators that live alongside sage-grouse on public lands.
Moreover, science shows that predator control measures are less effective than conserving sagebrush habitat and managing other uses of the land to avoid introducing novel predators.

Healthy habitat allows enough chicks to mature and stabilize population numbers without the need for predator control that would further disrupt the natural balance.
