Top Terrestrial Invasive Threats to Minnesota

  • Oriental bittersweet Celastrus orbiculatus
    Oriental bittersweet is a highly invasive vine that girdles trees and dominates the canopy, shading the under-story, and making it difficult for native plants to survive.

It is estimated that Minnesota's annual estimated loss due to the deleterious effects of terrestrial invasive species is $3 billion annually. This figure encompasses agricultural and natural resource pests, pathogens, and plants. The Minnesota Invasive Terrestrial Plants and Pests Center's sole focus on is cultivating promising lines of research to fund that will have a measureable impact in addressing these issues. 

The MITPPC has undertaken a strategic examination and prioritization of terrestrial invasives to help guide future research. The MITPPC recognizes, as well, the important role that our land manager partners and practicioners have in moving research into action. 

Additionally, the MITPPC convenes stakeholders on issues that cross both the agricultural and natural resource sectors. The Center's first endeavor, on the relationship between the soybean aphid and the decline of prairie butterflies, resulted in a recommendation to the MITPPC to develop and fund lines of research to test the hypothesis that the potentially harmful effect of soybean aphid insecticide drift has had a detrimental effect on prairie butterfly populations.
