Autumn olive is a non-native invasive plant that is found in many areas of Ohio, predominately in eastern and southern counties. Originally introduced as an ornamental plant, it has been used for erosion control, windbreaks, and mine reclamation sites. Spread by birds, the plant has disturbed habitats and invaded pastures across Ohio resulting in reduced land for livestock grazing.
A team of OSU Extension professionals is conducting a research trial at the Eastern Agricultural Research Station (EARS) in Caldwell, OH. The EARS facility encompasses roughly 2,000 acres of pasture and woodlands. Much of the property, 1,325 acres, includes former and active coal mining. The purpose of the research trial is to evaluate various herbicide treatments in the control of Autumn olive.
