Suppression program grants

Counties may apply for grants to fund their participation in the Department of Natural Resources gypsy moth suppression program if they have designated a coordinator. Tribal, federal and municipal lands are included in their county’s application; state lands (such as state parks) apply through their bureau.

The U.S. Forest Service sometimes provides cost-sharing. Up to 50 percent of the expenses directly related to the suppression program, aerial spray and administrative costs will be cost-shared based on the amount of money received from the U.S. Forest Service.

Eligible treatment areas must meet the following criteria:

  • be of at least 20 contiguous acres in a compact and regular shape;
  • have canopy coverage of 50 percent or more;
  • 50 percent or more of the canopy must be of the insect's preferred hosts listed in the Guide and Application Form for the DNR Gypsy Moth Suppression Program [PDF]; and
  • have the following minimum average number of egg masses per acre as estimated by survey methods described in the application materials and guide:
    • 500 egg masses per acre on residential or high use, public recreational land; and
    • 1000 egg masses per acre on rural land.

Applications are due from counties by the first Friday in December (a list of the documentation required for a complete application and the application form are provided in the Guide and Application Form for the DNR Gypsy Moth Suppression Program [PDF]). You can fill out the application form on-screen, print it and mail it to the address on the form.

Note: Sponsors receiving federal funds in their grant award must complete the Grant Partner Financial Data Report [PDF] (form 9300-230) and submit it with their Reimbursement Request [PDF] (form 2400-131a).

Expense worksheets are due July 15. Public notification response log sheets and payments for total cost of aerial spray are due April 1.
