Livestock grazing effects on sage-grouse

Research found that higher levels of grazing early in the growing season decline sage-grouse population trends, while similar levels of grazing later in the season correspond with increases. Grazing management actions can positively affect sage-grouse populations by increasing food resources and nesting cover.
