Numerous non-native plants have been introduced to Massachusetts in the United States and many of them have become invasive species. The Massachusetts Invasive Plant Advisory Group (MIPAG) is a voluntary collaborative that was established in 1995 to advise the Commonwealth of Massachusetts on invasive plant species. They have categorized invasive plants as "invasive," "likely invasive," and "potentially invasive." The following is a list of non-native invasive plant species established in Massachusetts.
An invasive plant in Massachusetts is a non-native species (including its subspecies, varieties, forms, synonyms, and cultivars) that establishes self-sustaining populations in native or minimally managed systems and causes ecological or economic harm by becoming dominant or disruptive.
A likely invasive plant in Massachusetts is a non-native species that has become naturalized but does not fully meet the criteria for designation as invasive.
A potentially invasive plant in Massachusetts is a non-native species which has not yet naturalized in the state, but is expected to become invasive in minimally managed habitats.
