MI HB4857

Amends the Noxious Weeds Act to explicitly exclude milkweed (any species of genus Asclepias) from the definition of noxious weeds.

Prevents local governments from classifying milkweed as a noxious weed or common nuisance under their own authority.

Maintains the existing list of 11 designated noxious weeds including Canada thistle, dodders, mustards, wild carrot, bindweed, perennial sowthistle, hoary alyssum, giant hogweed, ragweed, poison ivy, and poison sumac.

Allows local governments to designate other plants as noxious weeds, but only if they are not milkweed.

Effective 91 days after final adjournment of the 2024 Regular Session; approved by the Governor on March 12, 2024.
