Aquatic Invasive Species



Many aquatic invasive species (AIS) are now present in Minnesota, most notably Eurasian watermilfoil, zebra mussels, and spiny water flea. A new nasty invader, starry stonewort, has recently appeared and others are on Minnesota’s doorstep. These invaders threaten the current and future recreational enjoyment of our state’s waters and the economic sustainability of many communities dependent on Minnesota’s $13 billion tourism industry, largely centered on water and its adjacent natural resources. Not only can AIS impede recreation, but they change the ecosystem balance, potentially forever.

The Initiative Foundation will award a total of $3.6 million to fund a limited number of pilot projects to prevent the introduction or spread of aquatic invasive species (AIS) into Minnesota waters and to assess the effectiveness of these strategies. Funding for this program was recommended by the Lessard-Sams Outdoor Heritage Council (LSOHC) and approved by the Minnesota Legislature through the Outdoor Heritage Fund, one of four funds established by the 2008 Minnesota Clean Water Land & Legacy constitutional amendment.

The program is intended to fund pilot projects anywhere in Minnesota that are legal, effective and financially sustainable methods of preventing the spread of invasive species through a range of education and outreach, inspection and decontamination, enforcement, containment and/or other methods that can be administered locally.

Request for Proposals Now Open

Round 5 funding for pilot projects is an open application with no deadlines. Applications will be reviewed as received and funded as approved. Initial review and opportunity for questions and clarification will occur with two weeks of submitting a letter of inquiry. Full review and a funding decision will occur within four weeks of submission of an invited full proposal. The first step for project review is the online submission of a letter of inquiry (see apply/Login tab).  

**Eligible applicants are encouraged to discuss their project ideas with Program Manager John Sumption before submitting letters of inquiry. Contact John by email or call (218) 368-8304.

Who Is Eligible To Apply?

Eligibility applies statewide for: 

  • Local units of government including joint powers organizations
  • Tribal governments
  • Registered 501(c)(3) nonprofit organizations

Priority will be given to local partnerships that demonstrate the administrative, financial and logistical capacity to effectively implement innovative AIS prevention strategies. Collaboration is encouraged between local governments, lake associations, tourism- and water-related businesses, sporting groups, resorts and other interested organizations.

What Types Of Projects Are Considered Innovative And Eligible?

This program will fund only innovative and comprehensive strategies that accomplish one or more of the following:

  • Reach new audiences
  • Serve new geographic areas
  • Employ existing AIS prevention technologies in new ways
  • Pilot emerging prevention strategies, including containment of current infestations
  • Employ locally enforced experimental regulations on targeted waters
  • Pilot innovative methods of funding, administration, or implementation

Examples of eligible projects include, but are not limited to:

  • Strategies to identify pathway risks and enhance or manage access to and from targeted waters to control AIS.
  • Inspection and decontamination of watercraft and other resource user equipment to limit the spread of AIS to and from targeted waters.
  • Unique and/or new education and outreach approaches to targeted audiences.
  • A cooperative strategy to enhance enforcement of existing AIS laws, enact experimental local regulations, pilot new AIS prevention technologies, test new treatment methods/approaches for containment, or to utilize existing AIS prevention technologies in new ways. 

Read about innovative pilot projects currently funded.  

What Activities Are Not Eligible?

This program cannot fund:

  • Existing AIS prevention programs and/or strategies commonly being employed throughout Minnesota.
  • Existing AIS control projects on infested lakes or rivers unless they are specifically intended to prevent AIS spread to targeted uninfested waters or have a new and innovative approach to treatment. 
  • User fee or tax reduction, replacement of existing revenue streams or other supplanting of government funding.

What Are The Matching Requirements?

The Lessard-Sams Outdoor Heritage Council (LSOHC) in December 2014 approved the following match requirement amendments:

  • Outdoor Heritage funds can pay up to 50 percent of the project costs.
  • A 20 percent local match is required. The local match can include in-kind services or materials and must include the cost of program evaluation. 
  • The remaining 30 percent can be from any source including other state funds with the exclusion of other Outdoor Heritage Fund projects. County AIS Prevention Aid is an eligible match source.

Please note: Capital costs or purchases are not eligible for state funding but may be used as a project-related matching expense.

What Is The Application Process?

Applicants must submit an online letter of inquiry that includes:

  • Sponsoring organization information
  • Description of the targeted waters, recreational pressures and risk of infestation
  • AIS threats of concern
  • Proposed innovative strategies and potential implementation partners
  • Administrative and financial capacity to administer the program
  • Availability of current AIS survey data
  • A summary of local AIS education, monitoring and prevention/control efforts to date

A review committee will score the inquiries and invite a select group to submit full proposals. Before submitting a letter of inquiry, eligible applicants are encouraged to discuss their project ideas with Program Manager John Sumption. Contact John by email or call (218) 368-8304.

Additional Program Information

Selected projects will be required to ...

  • Provide current baseline data on the presence or absence of AIS in the targeted waters. Non-Outdoor Heritage matching funds must be used to complete the assessment.
  • Provide long-term solutions that are based on best available science. Projects will have a two-year implementation window.
  • Establish and conduct a reporting and monitoring program using a customized evaluation plan that will be designed for each project. Non-Outdoor Heritage funds must be used for the evaluation. Monitoring will be required for three to five years.

Quick Facts About Minnesota Invasives


Zebra Mussel

What is it? A fingernail-sized mussel that attach to solid surfaces. A native of Eastern Europe brought to the Great Lakes in ship ballasts, zebra mussels have been here for more than 20 years.

What does it do? Their presence causes more algae and weed growth and kills native clams.

Eurasian Water Milfoil

What is it? Eurasian milfoil was accidentally introduced to North America from Europe. It reached Midwestern states between the 1950s and 1980s, mostly hitching a ride on boats.

What does it do? It's notorious for its ability to choke water resources.

Pondweed.jpgCurly-Leaf Pondweed

What is it? Curly-leaf was first noted in Minnesota about 1910. It probably was accidentally introduced when common carp were intentionally brought to Minnesota.

What does it do? Curly-leaf generally grows in 3-10 feet of water. Curly-leaf tolerates low water clarity and will readily invade disturbed areas.

Loosestrife.jpgPurple Loosestrife

What is it? Loosestrife was introduced in the 1800s. It was distributed as an ornamental and is now found in 40 states.

What does it do? Loosestrive invades marshes and lakeshores, replacing cattails and other wetland plants.
