2021 Aquatic Invasive Species Control Grant Program

For control of curly-leaf pondweed, Eurasian watermilfoil and flowering rush

The 2021 application period for this program has ended. These grants will likely be offered again in 2022, with the application period likely opening in early 2022 (January or February). For questions, please contact the Aquatic Invasive Species Research & Grants Coordinator Jake Walsh at [email protected] or 651-724-2439.

Program Updates

Applications will not be reviewed on a first-come, first-served basis. Instead, all applications received within the 18-day application period will be randomly ordered and selected by this order until funds are spent. The grant program will likely run out of funds before all applications are reviewed for award offers.

We have updated our grant execution process to expedite grant execution (when all parties have signed the grant agreement and work can begin) by 2-3 weeks, allowing for more time to plan spring delineation surveys and treatments. Because this moves the signature from the authorized representative of the grantee organization to the application itself, we will not be able to accept applications from anyone other than the authorized representative of the grantee organization.

We have made several additional changes to the Control Grant Program compared to previous years. Important details about the 2021 Control Grants can be found in the Grant Request for Applications and Information document.


The Minnesota Department of Natural Resources (DNR) Invasive Species Program offers Aquatic Invasive Species Control Grants. These grants are intended to help fund the control of curly-leaf pondweed, Eurasian watermilfoil or flowering rush. This offer is an opportunity for local entities such as lake associations, watershed districts, cities and counties to receive state funding from the DNR for the control of these invasive aquatic plant species.

Funding is for reimbursement of expenses incurred while conducting local AIS control projects. Reimbursable expenses include the cost of the third-party delineation survey and the costs directly related to and solely for invasive plant control according to an Invasive Aquatic Plant Management (IAPM) Permit. As such, an IAPM Permit must be submitted in our online permitting system before submitting a grant application.

Funding Availability

An estimated $400,000 is available to fund grants for local AIS control projects. Award amounts will be determined by estimated project acreage during review by Invasive Species Program Staff. The maximum award amount may not exceed $5,000 (see Description of funding levels for projects with IAPM permits below). The state reserves the right to offer grant amounts that differ from the applicant’s request or the maximum award amount. Not all proposed projects will receive funding.

These grant funds can be used for projects that control Eurasian watermilfoil, curly-leaf pondweed or flowering rush using herbicides, mechanical control or a combination of both.

Grant awards will be limited to one control project grant per waterbody as defined by the waterbody’s unique eight-digit Lake ID number. In those applications for control projects that include control efforts for two or more target species that would require separate treatments, organizations can apply for a single grant that includes multiple IAPM permit applications. Project acreage will be summed across each species up to the maximum grant amount of $5,000. Applicants are encouraged to coordinate within their organization and with organizations with overlapping scope to ensure that one application is submitted per waterbody (eight-digit Lake ID number).

To receive funding for reimbursement of eligible costs under this grant program, you must:
1) be awarded a grant after completing the Invasive Aquatic Plant Management (IAPM) Permit and Control Grant applications,
2) arrange for a third-party delineation survey of the invasive plant to be controlled, and
3) complete and obtain an IAPM Permit for the work related to the control project.

Grantees must make all arrangements and pay all project expenses up front.

The DNR will reimburse grantees for eligible costs associated with the invasive species delineation and treatment up to the grant amount. Eligible costs include:

  • Delineation
  • Treatment or harvest by a contractor
  • Herbicide, if it is purchased separately
  • If harvesting is done by staff of the grantee, labor and other expenses related to maintaining and operating equipment

The purchase cost of durable equipment is not an eligible expense.

Please note the DNR cannot reimburse costs for work done before the grant agreement is signed by all parties or work that is found by the DNR to be unsatisfactory or performed in violation of federal, state or local law. In addition, while projects may be partially funded by external funding sources, a grantee may not receive reimbursement for costs that have already been reimbursed by another external funding source.

All work for executed grants must be completed by October 15, 2021.

How to Apply

This grant program will begin accepting applications at 12:00 a.m. (midnight) Friday, February 19, 2021. Applications received before this time will not be accepted. In order to provide grants in a timely manner, the final application deadline is 9:00 a.m. Monday, March 1, 2021.

  1. Apply for a new or renew a previous Invasive Aquatic Plant Management (IAPM) permit through the MPARS website, even though your required delineation has not been done. There will be an option in the permit application to identify that your project is linked to a Control Grant Application, which will allow you to postpone submitting a survey until your delineation is completed. You will have to upload your delineation map after it is completed or the past year’s map after it is approved by your DNR Specialist (see Request for Applications document). Your permit request will be reviewed and your permit issued at that time.
  2. Download a PDF copy of your 2021 IAPM permit application. (See Saving Your IAPM Permit Application document.)
  3. Review and fill out the Grant Application with Assurances form. The Application must include the signature of the person with delegated authority to sign the grant contract for your organization agreeing to the terms of the grant program.
  4. Return the 2021 Control Grant Application PDF and the 2021 IAPM Permit PDF via email to:

Jake Walsh (Email: [email protected])
Minnesota Department of Natural Resources
Ecological and Water Resources, Box 25
500 Lafayette Rd, St. Paul, MN 55155

If you anticipate challenges with returning these documents via email, please email by 4:30 p.m. Wednesday, February 24.

When you sign the Application with Assurances, you certify that you have read the application and that you will comply with the approved application, the assurances here and in the Grant Award Notification (GAN) and all other applicable federal regulations, state statutes and local policies.

Grant Application with Assurances

Online Permitting System for IAPM Permit Application

Obtaining an Invasive Aquatic Plant Management Permit

An IAPM Permit application must be submitted through our online permitting system (MPARS) before you submit your grant application. If possible, create an account in advance, review the system, and submit your permit application before this grant program begins accepting applications. A copy of your permit application must be submitted with your grant application. See Saving Your IAPM Permit Application for more details on how to save your application as a PDF.

Data Practices

Please note that the day after the grant application deadline, the name and address of all applicants and the amounts requested become public. All other data are nonpublic until the Grant Award Notice is completed. After the application review process is completed, all data (except trade secret data) become public.

Review Award Processes

Grants received within the application period will be reviewed for completeness. Completed and on-time applications will then be randomly ordered for selection. DNR Invasive Species Specialists will review and adjust proposed project acreages in this order until funds are spent. The grant program will likely run out of funds before all applications that were received during the application period are funded.

Grant awards will be determined by permitted acreage associated with the IAPM permit. Grants will provide $1500 for treatments estimated to be 10 acres or less. For each project greater than 10 acres, the grant will provide $1500 for the first ten acres and $150 per acre for the remaining estimated project acres. In those applications for control projects for two or target species and separate treatments, project acreage will be summed across each species for determining the grant award offer. No grant will be more than $5,000 regardless of the number of estimated acres.

We have updated our grant award notice process, to expedite grant execution (when all parties have signed the grant agreement and work can begin) by 2-3 weeks, allowing for more time to plan spring delineation surveys and treatments. Please note the following relevant changes to the process:

  • The grantee will agree to the terms of the grant by signing the Grant Application with Assurances document, which contains the terms of the grant agreement and will be incorporated by reference into the Grant Award Notification.
  • Grants will be fully executed with the official, signed Grant Award Notification sent to 2021 grant recipients. This document will contain all of the remaining details (e.g., grant award amount, award period, and necessary funding and encumbrance information) as well as the necessary DNR signatures to complete the grant execution.
  • With the grant fully executed at this stage, Control Grant Project work can begin immediately with the official Grant Award Notification.

Clarifications may be necessary before execution of the award. Applicants recommended for an award must wait until they receive the signed Grant Award Notification (GAN), before providing any services and before incurring expenditures. Any expenses incurred prior to the full execution of the GAN are not reimbursable and are the responsibility of the applicant/grantee.

Work Plan Requirements

Delineation Survey

Grant funds are intended to support projects that have a delineation survey done in 2021, prior to treatment. Some delineation surveys done in the mid to late summer of 2020 may be adequate to define treatment areas for 2021. If you believe a delineation survey done in 2020 is adequate to establish treatment areas in 2021, please include it with your permit application. It will be reviewed when your permit application is reviewed. If it is acceptable, the requirement for a new survey will be waived.

  • The delineation map must be submitted to complete the IAPM permit application originally submitted with the grant application, and the grantee must receive an IAPM permit to conduct the treatment work in the Control Grant Project. 
  • The delineation survey cannot be done by the same company that does the treatment. It must be done by a qualified third party.
    • Qualified staff or volunteers from the Grantee organization can do the delineation, but it must be acceptable to DNR Specialists who will review the survey. You should confirm with your Regional DNR Specialist whether they would be willing to review and possibly accept a survey done by qualified staff or volunteers in your organization prior to conducting a survey in this way.
  • Grantees must pay all survey expenses up front and make all arrangements.
  • The DNR reserves the right to request a new delineation survey.
  • If the delineation survey results in no areas suitable for treatment, the DNR will reimburse the cost of the delineation, up to the grant amount.


The DNR will only reimburse the cost of treatments done under and according to an IAPM permit. Grantees must pay all treatment expenses up front and make all arrangements. Treatment expenses from the same contractor that did the delineation (i.e., violated the third-party requirement for the delineation survey mentioned above) will not be eligible for reimbursement.
