Rocker and hunter Ted Nugent plans to sue the Department of Natural Resources over its order declaring swine used at special hunting ranches to be an invasive species. Nugent, who owns the Sunrise Acres Ranch near Jackson, claims that the invasive species order was illegally issued and is being illegally enforced. Nugent cited a loss of business through immense stress and hardship because of the DNR’s public campaign to unlawfully enact and enforce the order. A hunting ranch in Negaunee has also filed a notice of intent to sue on the issue. The DNR will begin actively enforcing the order in April. The order is legally effective, but the department delayed enforcement to allow the facilities time to remove swine.
