Oriental Bittersweet

Where is it Found: Oriental bittersweet has been reported to be invasive from Maine to North Carolina west to Wisconsin and Missour

    Where it came From:Oriental Bittersweet is an invasive, non-native vine that is native to China, Japan and Korea, Eastern  Asia

Accidental or Deliberate: Oriental Bittersweet was introduced into the United States in the 1860,s as an ornamental plant and it is still widely sold for landscaping despite its invasive qualities.

   What Harm has it Done: Oriental Bittersweet poses a significant threat to the native plant communicates.It grows rapidly and can shade out the vegetation that sport it. It girdles trees and shrubs cutting of the flow of water and nutrients. weakened trees,burdened with the weight of  massive woody  vine and leaves, are particularly vulnerable to damage from ice and windstorm. Oriental Bittersweet can spread from tree to tree in the forest canopy  When one tree falls or is cut down, attached trees may be pulled down, also.

    What can be done to Prevent further Spreading:  1.Prioritize high value sites where success can be achieved for treatment. 2. Choose appropriate control methods, given site conditions and available resources. 3. If using herbicide, be sure to read the product label before finalizing plans. Is there potential for harm to non-target species? Have you made adequate provisions to minimize damage? 4. Do these control methods require any permits (i.e. herbicide application in wetlands, prescribed burning)? 5. Prevent further spread; focus on mature plants, particularly plants in full sun with abundant fruit. 6. Eradicate smaller satellite pop

        What native species have been impacted: grows as a vine that smothers plants and uproots trees due to its weight.
