Drones can spot invasive Oriental bittersweet vine
The Oriental bittersweet vine is known to smother and break trees. The destructive plant has damaged forested areas in southeastern Minnesota.
Researchers recently launched a drone from Red Wing to test the usefulness of unmanned aerial vehicles to spot invasive plants. The project is part of ongoing efforts to eradicate it. "One of the important things is to find it, so then we can go in and get rid of it," says Angela Gupta, Extension Educator in forestry. Drones can be deployed to areas such as bluffs and river valleys where the landscape is too challenging to search for Oriental bittersweet from the ground
A quadcopter drone, equipped with a camera to record the flight, completed a brief pre-programmed route before returning to land. This test will help determine which sensors to use, the impact of lighting conditions and how best to program the drone's flight pattern.
The research is a joint venture by the Minnesota Department of Agriculture, University of Minnesota Extension, Conservation Corps Minnesota and St. Croix River Association. It is funded through an Environment and Natural Resources Trust Fund grant.
