Around the Refuge

Invasives - an ongoing battle

Oriental Bittersweet

Oriental bittersweet, while it may be pretty, is choking off important vegetation and creating havoc in the Northeast. Originally grown as an ornamental, it has spread throughout the region where its aggressive growth can smother trees, shrubs and other vegetation. This leafy, deciduous, sprawling, twining vine climbs up and over woody plants and other supporting objects. Its dense foliage can shade out and eventually kill saplings and trees. Oriental bittersweet climbs over and smothers herbaceous plants on the ground as well as tall trees and shrubs. Its sprawling growth monopolizes light and water resources. In can twine tightly as it climbs, constricting and eventually girdling shrubs, tree limbs or entire trees as both continue to grow. Tangled mats of vines in trees can make them top-heavy and increase their susceptibility to wind and ice damage. Because Oriental bittersweet can hybridize with American bittersweet, in may someday threaten the genetic integrity of the native species. The refuge actively controls Oriental bittersweet to ensure our natural diversity and heritage, by aiding our native plants, trees, and shrubs. Reference:
