Russian olive is native to Europe. It is commonly used as an ornamental or windbreak tree. It can be extremely invasive in riparian areas, out-compete desirable native plants, and restrict access to waterways by livestock, wildlife, and people. It is not of major concern in Natrona County, but is found on creek banks and the North Platte River.
Chemical control is done by method of cut stump treatment. Cut stumps must be treated chemically or the tree will continue to reproduce by shoots! Contact your local weed and pest for specific recommendations.
