In the 1950s, America planted crown vetch beside roads to control erosion; it now occurs in nearly every state and forms dense mats that crowd out native plants

Crown vetch was introduced to the United States for erosion control purposes. This plant spread rapidly across the country, becoming a widespread issue. Its ability to reproduce from fragments makes removal extremely difficult. Invasive crown vetch displaces native plants and alters natural habitats. Management of this once-beneficial plant now poses a significant environmental challenge.
