Russian Olive tree example
Russian Olive (Elaeagnus angustifolia)

Unique Features: A spiny shrub or tree that grows up to 40 feet tall. Russian olive trees are non-native to the United States. Many of the Russian olive trees in the Wells Project area were planted in the 1980s as habitat for wildlife. They produce an abundance of fruit that are eaten by many bird species. They also provide structure for bird nesting and roosting, important components in ecosystems with limited trees.

The Russian olive is now classified as a Class C weed by the Washington State Noxious Weed Control Board because it can crowd out important native riparian plant communities and can spread prolifically into areas where it is not desired.
