Report on EDDMapSRussian Olive
Elaeagnus angustifolia
Overview
Russian olive is a small tree or large shrub from Eurasia that was widely planted for windbreaks and wildlife habitat. It is now illegal to sell in Utah. It invades riparian areas, displacing native cottonwood-willow communities and reducing wildlife habitat quality.
How to Identify
Small tree or large shrub 10-30 feet tall. Distinctive silver-gray, lance-shaped leaves. Small, fragrant yellow flowers. Olive-like fruits. Thorny branches. Shredding, gray-brown bark.
Control Methods
Cut-stump herbicide treatment is most effective. Mechanical removal for small trees. Do not plant or purchase. Report large infestations to your county weed superintendent.
Herbicide Recommendations
Triclopyr or imazapyr as cut-stump treatment. Apply immediately after cutting.
⚠️ Always read and follow pesticide label directions. Contact your county weed superintendent for site-specific recommendations. Permits may be required near water.
