Impacts of this species 

Autumn olive out-competes and displaces native plants by creating a dense shade that hinders growth of native vegetation that need sunlight. They can produce up to 200,000 seeds in a year. These shrubs grow over a wide variety of habitats as their nitrogen-fixing roots nodules allow them to grow in harsh environments with unfavorable soils. They also grow quickly and with comparatively little resources, so they can take over in a short period of time. They germinate easily and even attempts at removing autumn olive may cause unwanted spreading.
