Missouri Invasive Plant Council (MoIP) - to identify and control invasive plants

Missouri’s Glaciated Plains Top Expanding Invasive Plants, 2021

Northern Missouri’s Glaciated Plains Region is threatened by many invasive plants. Because of their vigorous expansion, the plants pictured below are particularly important to identify and control. Learning how to identify and remove uncontrolled plants from your property is the first step in protecting the vitality of Missouri’s natural and agricultural lands.

The Missouri Invasive Plant Council’s (MoIP) 2021 List of Expanding Invasive Plants for this region draws data from MoIP’s invasive plant assessment. This assessment was compiled and reviewed by experienced field biologists in Missouri. In addition to identifying invasive plant abundance and assessing the severity of the plants’ impact on natural communities, biologists estimated how rapidly the species’ ranges will expand to form new occurrences throughout Missouri’s Glaciated Plains ecological region over the next 10 years. The results follow here.

Because of their vigorous expansion, the species listed on the 2021 Top Invasive Plants Expanding in Missouri’s Glaciated Plains region are particularly important to identify and control. See below for links to resources on how to identify and control each plant.

  • Invasive: An aggressive, non-native species whose presence causes or is likely to cause economic or environmental harm
  • Expanding: These plants are the biggest threat in relation to expansion, as they continue to spread at a higher rate

This assessment will be updated every several years based on additional and ongoing in-the-field observations and reviews.
