Foragers & Hikers - Garlic Mustard Being Sprayed with Herbicide

❗️ Attention Foragers and Hikers ❗️ We are starting to apply herbicide in various parks to slow the spread of the invasive species, Garlic Mustard. Right now, please do NOT forage on your own. Contact ConservationVolunteers@polkcountyiowa.gov if you are looking for patches of garlic mustard that have not been sprayed, or sign up for one of our foraging events.
