Russian Olive

About Russian Olive in Alberta

Russian Olive is an introduced Eurasian shrub or small tree historically planted in Alberta for shelterbelts, farmsteads, erosion control, difficult dry sites, and some urban landscapes, but it now carries clear invasive-risk caution. Alberta evidence supports both its older prairie utility and its ecological concern: it is flagged by Alberta invasive-plant sources and recorded as escaped from cultivation in southern Alberta at low density. For ARA, old shelterbelt or farmstead Russian olives may have planting-history value, but any heritage interpretation must also document invasion risk and avoid encouraging further spread.

Identification: Leaves are narrow and silvery, covered with scales that give the plant a gray-green to silver look. This silver foliage is one of the strongest distance and close-inspection traits, but it creates confusion with native wolf willow.

Alberta range and habitat: Russian olive is not native to Alberta. Alberta invasive-cost literature records it as escaped from cultivation in southern Alberta at low density, and invasive-plant sources flag riparian invasion risk.
