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. ]

The eventual replacement of native plains cottonwood (Populus deltoides) forests by Russian olive (Elaeagnus angustifolia) is a serious threat to biodiversity on floodplains in western North America. Low palatability of Russian olive saplings and trees, easily dispersed seed, and three-year seed viability give Russian olive a competitive advantage over native woody riparian plants.

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.

Phragmites australis (common reed) is a widely established invasive plant in wetlands and riparian areas. A three-year study was initiated in Nebraska to evaluate targeted cattle grazing, herbicide effects, and the nutritive value of this species. Results suggest that cattle will utilize Phragmites, and the cumulative effect of grazing has the potential to reduce P. australis populations. However, other methods would have to be used for greater control and site restoration. READ FULL PAPER.
The Pollinator Protection Initiative Task Force charged the Environmental Protection Agency to identify a process to evaluate the impact of pesticides on pollinators, develop plans to manage pollinators and enhance pollinator habitat. As a result, the National Association of State Departments of Agriculture began developing State Managed Pollinator Protection Plans (MP3).Read More
Spotted knapweed is a prohibited noxious weed that is primarily controlled with auxinic herbicides. A population collected from a managed rangeland in East Kootenay, BC, was highly resistant to both clopyralid and picloram, with R/S ratios of >25 600 and 28, respectively. This is the first report of resistance in spotted knapweed.Read More
