Sagebrush restoration after wildfires has had limited success, and success likely varies considerably by method, site characteristics and interactions between them.� Our objective was to compare different sagebrush restoration methods (broadcast seeding, broadcast seeding and packing, planting sagebrush seedlings, seed pillows, and natural recovery) across elevation gradients ranging from 1219 to > 2134 m (4000 to 7000 ft).� We used 350 plots spread across approximately a million acres of sagebrush rangelands in Oregon that burned in two mega-fires in 2012.� All sagebrush restoration methods were seeded in the fall of 2013, and then repeated on adjacent plots in 2014 with the exception of sagebrush seedlings; sagebrush seedlings were planted in the spring of 2014 and 2015.� For Wyoming big sagebrush plots (elevation 4000 to 5000 ft), plots seeded in the fall on 2013 had on average < 0.01 sagebrush plants/m� for all restoration methods.� Plots seeded in the fall of 2014 had an average of 12.0 sagebrush plants/m� (natural recovery plots had 0.2 sagebrush plants/m�).� Precipitation was on average 4% less than the 30 year average between September 2013 and August 2014; however, between September 2014 and May 2015 precipitation was on average 36% greater than the 30 year average.� For mountain big sagebrush plots (elevation 5500 to 7000 ft), seeded plots were on average 4-fold greater than natural recovery plots (5.3 vs 1.2 plants/m�) for both seeded years.� Perennial bunchgrass competition with sagebrush seedlings may have influenced sagebrush densities particularly in higher elevation plots; mountain big sagebrush plots had on average 7.8 plants/m�, whereas Wyoming big sagebrush plot had on average 1.1 plants/m�.� Data is being further analyzed based on a suite of environmental characteristics with the expectation that this information will help land managers successfully restore sage-grouse habitat after wildfires by pairing restoration methods with site characteristics.
