Investigating distribution and treatments for effective mechanical and herbicide application for controlling oriental bittersweet (Celastrus orbiculatus Thunb.) vines in an Appalachian hardwood forest

This document discusses two exotic-invasive plant species related research studies that were conducted in an Appalachian hardwood forest in north central West Virginia. The first study characterizes the distribution of oriental bittersweet (Celastrus orbiculatus Thunb.) in a timber harvested area in north central West Virginia. Canopy profiles were used to create a visual picture of distribution of C. orbiculatus vines from the forest edge transition to the interior of the forest. In the second study, the efficacy of herbicides triclopyr and glyphosate were tested using basal bark, cut-stump, mechanical cut, and deer fencing to control C. orbiculatus
