Battling Invasive Plants In Lewis and Clark National Historical Park: The Video
Much has changed since Lewis and Clark took a hike across the western United States. Among those changes has been an infusion of non-native vegetation that threatens to overrun native vegetation. At Lewis and Clark National Historical Park, researchers are working to wipe out the intruders.
This video, produced by the North Coast and Cascades Science Learning Network, takes a look at this field work.
