What is it about?
Almost all habitats used by greater sage-grouse are grazed by domestic livestock, and rotational grazing systems have been proposed as a way to increase compatibility between livestock grazing and greater sage-grouse. We studied nesting sage-grouse on >30 central Montana ranches to test whether rotational grazing systems and rest from grazing provided additional hiding cover or increased nest success rates. We observed only minor differences in hiding cover and found little evidence that rotational grazing systems or rest from grazing increased nest success relative to ranches using other types of grazing management.

Why is it important?
Grazing occurs on almost all lands occupied by greater sage-grouse, yet there have been very few studies linking grazing to sage-grouse behavior or demography. Therefore, most guidelines for managing grazing in sage-grouse habitat are based on indirect or circumstantial evidence. Our study tests a management practice commonly recommended to improve habitat quality and finds little evidence that it produces the intended benefits.
