Genus Elaeagnus (Elaeagnaceae) in the south of the Russian Far East

The spread of two species of oleaster – Elaeagnus angustifolia and E. multiflora, cultivated and wild in the south of the Far East of Russia, has been clarified. Their invasive potential is assessed. Only a single case of invasion of E. multiflora into natural plant communities in vicinity of the Nevelsk in southern Sakhalin has been identified. Previously, this species was known only in culture or as wild in places of former culture in the southwest of Sakhalin and Kunashir Island (southern Kuril Islands).
