Dr. Evelyn Beaury joins us for a look at the state of invasive plant species in the United States, which threats are greatest to the well-being of our native ecosystems, and how changing climates and land-use patterns can expedite the spread of invasive species.  From knotweed in the northeast U.S. to kudzu in the south and cheatgrass in the west, hear how these species can overwhelm native plants and habitats—and discover ways that each of us can make a difference to stop them.
