英文摘要	The Yakima Training Center (YTC) sage grouse population is one of only two remnant populations of sage grouse remaining in the state of Washington. Sage grouse are considered candidates for listing as a state threatened species. The purpose of the work was to identify sage grouse population characteristics, habitat preferences, and land areas used by sage grouse to assist YTC environmental management staff and military training personnel in both managing sage grouse and planning training activities. The ultimate objective is to protect sage grouse and sage grouse habitat without compromising military training objectives. The sage grouse population on the YTC is small but appears to have remained stable during the past few years. Two distinct subpopulations of grouse appear to exist, each occupying a distinct geographical region and using separate lek areas. Nesting and brooding hens select for long angle slopes and moderate elevations, which places the birds in preferred troop-training areas. The greatest potential impact of training activities on sage grouse seems to be related to habitat loss, although disturbance at leks during the breeding season also could have major impacts on breeding success. The creation of habitat maps for the YTC showing vegetation features most valued by sage grouse is recommended because it would provide habitat managers and military training planner`s with a means to protect grouse habitat while making training assignments. An analysis of sage grouse habitat quality, as impacted by training activity, would also assist habitat managers in making decisions regarding habitat restoration and protection.
