Coal mining has caused large-scale disturbance on over 1.5 million acres in Appalachia. Invasive, non-native autumn olive was historically planted on former coalfields and now impedes reclamation efforts. Studies conducted by Virginia Tech show that cutting and applying Garlon ® 4 Ultra (20% v/v with basal oil) resulted in less autumn olive regeneration than cutting alone. This treatment appears to provide greater assurance that established desirable trees will persist over the long term.
