Current sage grouse distribution Historical sage grouse distribution County Stream Figure III-l. Current and historical distribution of sage grouse in Montana. Map provided by MFWP Information Services. Breeding Wallestad (1975) found strutting grounds or "leks," where breeding actually occurs, to be key activity areas within wintering-nesting complexes. Leks most often consist of clearings surrounded by sagebrush cover. Such areas may include natural clearings, old burns, or ground cleared by homesteaders. In Idaho, sage grouse used recent burns or manmade clearings as leks only in the absence of natural openings (Connelly et al. 1981). Wallestad and Schladweiler (1974) measured sagebrush at feeding and loafing sites of strutting cocks on the Yellow Water Triangle (YWT) in central Montana; 80 percent of these sites had a sagebrush canopy of 20-50 percent. Average sagebrush canopy overall was 32 percent (Eng and Schladweiler 1972). Slightly more than half of the total sagebrush plants measured at sites used by sage grouse occurred in the 6- tol2-in (15-30 cm) height class. Sage grouse invariably prefer sagebrush for nesting cover across their inhabited range (Patterson 1952, Klebenow 1969, Wallestad and Pyrah 1974, Sveum et al. 1998). Concealment was the basic requirement of nesting cover, and nest fate may be positively associated with tall grass cover and medium-height shrub cover collectively.
