MI HB6556

Adds definition of "MISIN" (Midwest Invasive Species Information Network) to the Natural Resources and Environmental Protection Act and requires DNR and MDARD to review species listed by MISIN for prohibited or restricted species designation.

Establishes timeline for reviewing MISIN-listed species: departments must complete 25% of required reviews by June 1, 2024, with additional 25% by June 1 each subsequent year for three years; new MISIN listings must be reviewed within 90 days.

Requires relevant commission to list or determine not to list a species within 60 days after department completes its review.

Clarifies that department review of aquatic species must include those listed or delisted as injurious wildlife under federal Lacey Act and plants designated as noxious weeds under the federal Plant Protection Act, with 180-day review deadline following federal changes.

Updates cross-references in section 41303 to reflect renumbered subsections regarding conditions for harvesting and possessing naturalized aquatic restricted species.
