• “…identified positive and negative impacts of livestock on sage grouse and habitat.”
• “Replicated field experiments are needed to determine widespread relative effects of grazing treatments…on sage grouse…”

Hypotheses
• 1) Rotational grazing results in increased grass height/cover and higher abundance of forbs.
• 2) Rotational grazing practices have higher sage-grouse nesting success, survival, and population vital rates.
