Abstract	During the 2016 greater sage-grouse breeding season, 1,908 aerial and ground lek surveys were conducted at 768 individual lek sites comprising 501 lek complexes. Surveys were conducted at 66.0% of known lek sites in the state, which was the greatest proportion of leks ever surveyed in Oregon. Survey effort during 2016 increased 33.5%, 13.1%, and 9.1% over survey effort in 2015, in terms of number of surveys conducted, number of leks surveyed, and number of complexes surveyed, respectively. Results from these surveys indicate the sage-grouse spring breeding population in Oregon increased by 14.0% between 2015 and 2016, to 22,218 individuals (± 1,662 individuals). Magnitude of population trend was variable across the state, however populations increased in all BLM Districts/Resource Areas analyzed (range: +5.3% in Prineville BLM District to + 26.5% in Lakeview BLM District), with the exception of the population in the Baker Resource area, which experienced an estimated 10.7% decline.
