Sage Grouse Nest Locations in Relation to Leks

Abstract

We tested 2 predictions about the locations of nets of lek-forming species to evaluate a guideline developed to protect sage grouse (Centrocercus urophasianus) nesting habitat. Sage grouse (n=37) in southeastern Idaho did not attempt to nest midway between leks, as 1 hypothesis suggests. Neither was there evidence indicating that areas surrounding a lek are important for nesting, as a second hypothesis suggests. Because distribution of sage grouse nests was random with respect to lek location, nesting habitat protection based on either hypothesis affords no special protection for nests
