Invasive Plants

In May 2007 the legislature passed and the Governor signed a resolve directing the Department of Agriculture to study invasive terrestrial plant species. The intention of this resolve was to develop a process with criteria for listing potentially invasive terrestrial plant species that could impact natural ecosystems in Maine. Plants evaluated using this system would be those that are commercially distributed and not necessarily weeds in the landscape. The Commissioner appointed a committee to study the issue and a report was presented to the legislature in February 2008. Invasive Plant Report (PDF) (DOC)

In 2011 a new rule was adopted outlining the criteria for listing invasive terrestrial plants. Invasive Terrestrial Plant Rule (DOC)
