Many invasive species are prohibited or restricted by state or federal laws

  • Federal law prohibits the interstate transportation, delivery, receipt or sales of alligator grass, water chestnut plants or water hyacinth plants or their seeds. Review the law (18 U.S. Code §46).
  • Michigan laws regulate the possession and sale of certain plant species which are considered undesirable from agricultural as well as environmental viewpoints. See a list of prohibited, restricted and noxious weeds.
