Invasive Species: Russian Olive
The Russian Olive Tree, Elaeagnus angustifolia,
is native to Western Asia. The exact date of
introduction to Idaho is not known, but is
estimated to be in the 1800s. Their bark is
silvery, but can be thorny. Leaves are light
green and oblong. In May and June, yellow
flowers are seen. Russian Olives were planted
by farmers as windbreaks along roads and
streams. This tree is resistant to harsh
conditions. It is able to thrive on little water
and in sandy soil. The seeds, distributed
by birds, are resilient. The Russian Olive
is said to have “escaped cultivation” and
become naturalized. It dominates streamside
ecology and has facilitated the rise of
other non-native species. It is considered a
noxious weed. Many believe the dominance
of the Russian Olive has contributed to the
disappearance of native species.
