This publication is part of a series that provides an overview of the presence of invasive plant species monitored on an extensive systematic network of plots measured by the Forest Inventory and Analysis (FIA) program of the U.S. Forest Service, Northern Research Station (NRS). Each research note features one of the invasive plants monitored on forested plots by NRS FIA in the 24 states of the Midwestern and Northeastern United States. Oriental bittersweet (Celastrus orbiculatus; also known as Asian bittersweet) is a woody vine that is native to China, Korea, and Japan that was introduced as an ornamental around 1860 (Kaufman and Kaufman 2007).
