Maryland Invasive Plants Prevention and Control

Introduction

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.
