Cut-stump application of triclopyr provided 96% control of Russian olive the year following treatment.  Seeded native species did not have trouble establishing once adequate spring moisture occurred in the second growing season after Russian-olive removal, indicating that removal did not present substantial obstacles to successful revegetation. Follow-up control of Russian-olive is critical after initial treatment. [ READ FULL ABSTRACT. ]

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.

Integrating herbicides and revegetation to restore rangeland infested with spotted knapweed (Centaurea stoebe) and downy brome (Bromus tectorum)

(By Mangold et al. 2014) Some rangeland plant communities previously comprised of native grasses and forbs are now co-dominated by a complex of invasive forbs and annual grasses. Herbicide combinations were applied to control spotted knapweed (Centaurea stoebe) and downy brome (Bromus tectorum) followed by re-seeding with desirable grasses in western Montana.
