Russian
Olive - Elaeagnus angustifolia L. -
was introduced into North America in the late
19th century, and subsequently escaped cultivation because its fruits
are relished by birds which disperse the seeds. Russian-olive is
considered to be an invasive species in many places in the United States
because it thrives on poor soil, has low seedling mortality rates,
matures in a few years, and outcompetes wild native vegetation. It often
invades river or stream banks where cottonwoods have died. |
