SciencePhoto: HT WorldRussian Olive Became Invasive in California and 16 Western States
Introduced in the early 1900s to North America for windbreaks and soil stability, Russian olive is native to Europe and Asia. It has become invasive in California and 16 other Western states, spreading along riverbanks and displacing native plants. Difficult to remove due to deep roots, early detection and removal before flowering is recommended by wildlife agencies.
