A Notice of Final Action for the Maryland Invasive Plant Regulations was published in the Maryland Register on Friday, February 3. These regulations went into effect February 13. The updated regulations add a total of four new species to the Tier 1 and Tier 2 lists established by the original invasive plant regulations (April 2016). Weed risk assessments are ongoing, and additional plant species will be added to the lists through the regulatory process as they are completed and approved. These science-based assessments are the foundation for decisions regarding a plant’s invasive status in the state. Full assessment reports are available on the Maryland Invasive Plants Prevention and Control website.
