Peninsula State Park of Door County Combats Garlic Mustard

A member of The Wild Ones pulls garlic mustard below Sven’s Bluff in Peninsula State Park. Garlic mustard, an invasive species, crowds out native flowers and tree seedlings. While Peninsula State Park uses herbicide to combat garlic mustard at some sites, the fragile nature of the species below the bluff preclude herbicide use.
