Many riparian areas along the Yellowstone River and other rivers in the West have converted to dense Russian olive stands, reducing agricultural and ecological value of these lands. A study was initiated in 2010 along the Yellowstone River in Montana to determine if restoration was necessary following Russian olive removal, and then establish the effectiveness of four restoration strategies. Results of the study after four years indicate that herbaceous seeding with planted shrubs had the lowest cover of invasive annual grass. Native species are continuing to establish at the site, and seeded herbaceous species cover is continuing to increase over time.
