Invasive plants are really good at being bad. They’re hard to get rid of, and a new study finds that even if you rip them out, they can have lingering effects for years.
Dan Tekiela is an invasive plant ecologist at the University of Wyoming. He studied Japanese stiltgrass, and calls it one of the top three worst invasive plants in the eastern U.S.
Tekiela says they removed the plant from several sites. Three years later, things were worse.
“We found the disturbance of us removing that invader actually promoted other weedy and invasive species,” he says.
