Maryland Invasive Plants Prevention and Control

Invasive plants threaten native plant health and biodiversity in both agricultural and natural systems in Maryland. Many of these problematic plants are imported, bred, distributed, and promoted for sale in the landscape and nursery industries. Maryland's Invasive Plant Advisory Committee (IPAC) was established by legislative mandate in October 2011. The IPAC's primary responsibility is to advise the Maryland Secretary of Agriculture on regulating the sale of invasive plants and preventing them from entering Maryland or from spreading further into the state. 

On June 1, 2024, significant changes were made to the invasive plant law. As a result, the website is currently undergoing updates to reflect these changes. You can find more information about Senate Bill 915 regarding the invasive plant species regulation here.
