The first five weed risk assessments (WRAs) are complete. See the list on the right side of this page with links to the documents. The recommended rankings will be published in regulations that will be posted in draft form on this Website soon. (June 12, 2015)
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 Secretary of Agriculture on
regulating the sale of invasive plants, and preventing them from entering
Maryland or from spreading further in the state. Using a scientific weed risk
assessment protocol, IPAC will classify invasive plants as Tier 1 or Tier 2 and
recommend regulations to reduce the risk of invasive plants in Maryland. See list of IPAC Members
Initial regulations were promulgated in January of 2013. See the Maryland Regulation of Invasive Plants regulations here. The remaining regulations, including proposed Tier 1 and Tier 2 plant lists are expected to be ready in April of 2015. Draft regulations will be posted on this site for preliminary review and comment prior to submission of the final proposed regulations.
