This is the gateway to information about invasive species and the efforts to address them in Minnesota. It includes information about the Minnesota Invasive Species Advisory Council (MISAC), rankings of invasive species threats to the state, how to identify and report invasive species sightings, informational products, invasive species regulations, contact information for programs and people who work on invasive species, as well as links to select species profiles, and links to other websites about invasive species.


The Minnesota Invasive Species Advisory Council (MISAC), a diverse group with a common interest in battling nonnative invasive species in Minnesota, was initiated in May 2001. The Council was formed in response to Presidential Executive Order 13112 on invasive species, the National Invasive Species Management Plan, and Minnesota Legislation that encouraged the state to plan and take action on invasive species. An Interagency Exotic Species Task Force, initially formed in 1990, preceded the current state invasive species council.

The council has about 85 members and representative organizations involved in various aspects of invasive species research, prevention, and management. 

The purpose of the Minnesota Invasive Species Advisory Council is to provide communication, coordination, and integration among member organizations to implement elements of the Minnesota Statewide Invasive Species Management Plan by:

  • Promoting communication and cooperation among organizations involved in invasive species issues.

  • Advocating for research and management for the species and pathways deemed greatest risk.

  • Coordinating outreach on invasive species (such as the MISAC calendar)

  • Recognizing outstanding and noteworthy work related to invasive species and encouraging such work through the Carol Mortensen Award.

  • Supporting state-wide and multi-state conferences related to invasive species issues.

  • Supporting trainings and field visits related to invasive species.

  • Maintaining the MISAC website to help the public locate invasive species resources.

These functions support, but do not supersede, the goals and responsibilities of member organizations.

The Departments of Agriculture and Natural Resources are responsible for coordinating the management of invasive species in the state. Department of Agriculture staff conduct surveys for invasive pests such as gypsy moth, emerald ash borer, Grecian foxglove, bark beetles, soybean rust, sudden oak death and chrysanthemum white rust disease and also oversee the state noxious weed and seed laws. The DNR is responsible for aquatic invasive species and vertebrate terrestrial invasive species such as zebra mussel, Eurasian water milfoil, flowering rush, curly-leaf pondweed, mute swans, invasive fish and purple loosestrife. See the summary of regulating authorities for various invasive species for more information.

Vision Statement

In Minnesota, the introduction and establishment of new terrestrial and aquatic invasive species are prevented, existing populations are contained, and the impacts of any remaining invasive species are minimized.

Mission Statement

To provide leadership to prevent the spread and reduce the harmful impacts of aquatic and terrestrial invasive species to Minnesota landscapes, economies, and the citizens of the State of Minnesota by promoting invasive species awareness, prevention, and management through research, education and regulation in cooperation with local, state, tribal, and federal partners.

Guiding Principles

The Minnesota Invasive Species Advisory Council (MISAC) supports invasive species prevention and management efforts that are proactive, science-based, stakeholder-sensitive and coordinated, have a statewide focus, and are adequately staffed and funded to achieve meaningful and measurable outcomes based on the following core principles:

  • Coordinated Cooperative Partnerships

  • Prevention First & Foremost

  • Early Detection & Rapid Response

  • Prioritized Management Strategies

  • Defined Measurable Outcomes

  • Critical Review & Adaption
